BMW NBT, NBT-ENTRY, NBT2 EVO, ENTRYNAV1, ENTRYNAV2 REPAIR SERVICE AND DETAILED INFO

BMW F10, F01, F02, F25, F07, F30, F32, F36, F15, F16,F80 F82 AND OTHERS. YEARS 2012-2016.

OK, sorry we didn’t have time to update our site lately due to very busy CCC/CIC repairs, seriously we barely can keep up with it, even though we don’t need that many repairs, but since we offer these services, it would not have been right to go on 6 months vacation and let everyone be pissed with their faulty units, yes, imagine we are the only one small company, who can repair these complex units and code them on the bench to match your VIN, so you don’t have to see any dealers!

THIS IS HOW UNITS LOOK LIKE: NBT NBT- EVO NBT-ENTRY

Anyways back to the main topic NBT- Next Big Thing, this is how BMW decided with the new name for new generation navigation system in 2013. Yes its really new and compared to CIC unit is a huge breakthrough everywhere: software, hardware, storage, security etc etc.

NBT WAS UPDATED TO NBT2 EVO IN 2016, BASICALLY BMW UPDATES NAVI UNITS EVERY 3 YEARS. NBT2 SUPPORTS APPLE CARPLAY AND HAS BETTER HARDWARE INCLUDING EXTRA RAM 4GB.

So lets talk about main NBT features:

Now we have 2 computer systems in one: QNX (Linux) Jacinto CPU running all code for communication between your car and HU NBT unit +INTEL X86 CPU and NVIDIA running multimedia (CIC unit had only one 700MHZ risk CPU running everything). This is how we are getting very quick smooth HD graphics independent from QNX JACINTO CPU. So basically there are 2 laptops in one unit communication with each other using QNET high speed network!
NBT now contains Bluetooth and WiFi modules inside, all you need is ATM telephone module!!! remember in older units everything was separate on the MOST bus, which was cumbersome and finding faulty unit was a hassle! Now you only have TOP HIFI logic7 amp sitting on the MOST bus, and only if your car was equipped with logic 7 amplifier, so troubleshooting is much easier now and in case of amp failure you get “NO WARNING TONES” message, telling you MOST bus has issues.
NBT comes with 300$ 200GB TOSHIBA endurostar automotive HDD and they go bad. HDD is now locked to NBT unit individually, meaning you can not read HDD or replace it without HDD security installed. YES it is not easy like it was used to be with CIC units where HDD would fit from any CIC unit. So they sort of protected personal data and at the same time made it really hard just to replace HDD, so they want you you replace entire HU NBT if HDD failed.
NBT is much better built unit, than CIC unit and finally it comes with good cooling system and has vent holes for better ventilation. All in all its very nice inside with highest quality!!! Please don’t think it doesn’t cost much to produce these units for HK BMW. I’m sure they spent 100+ millions on development alone, and parts are very expensive too, so I roughly I would say it costs at least 600-700$ to build this unit for Harman Kardon. Yes its very complex and the most complicated unit in your car, YES THE MOST COMPLICATED UNIT in your car, all other nits are quite simple vs HU NBT, for example DME or engine module has only one CPU controlling injectors and tons of different sensors, but its not even close to complexity of your NBT unit
NBT contains FSC codes for NAVI, MAPS, VOICE APPS and they are VIN coded, so if you think of buying a cheap unit from junk yard, think twice: you will get a unit which will not work in your car properly-lots of functions and options will not match your car (unless you got lucky and donor car had same options like yours). For example PDC, cameras and so on might not work, but its not the worst part, the worst part you will not be able to use navigation or voice control or sat radio or BMW apps. YOU NEED TO CODE YOUR NBT UNIT AND UPLOAD CORRECT FSC CODES (ISSUED BY BMW SERVER) IN ORDER TO RESTORE FULLY FUNCTIONAL NBT UNIT. WHEN WE REPAIR NBT NITS WE UPLOAD ALL CODES AND EVEN TURN OF BMW APPS CODE IF REQUESTED AND CODE IT TO YOUR VIN (WE BUILT SPECIAL APP TO AUTOMATICALLY EMULATE YOUR CAR ON THE BENCH PRETTY MUCH)
NBT DOES NOT SUPPORT SSD DRIVES UNLIKE NBT 2 EVO. BE CAREFUL NBT EVO HAS COMPNENT PROTECTION MODE, MEANING IT WILL DISABLE OR BRICK YOUR NBT EVO YUNIT IF YOU CONNECTED USED NBT UNIT TO YOUR CAR WITH DIFFERENT VIN. YOU CAN ONLY CONNECT IT WITH EMULATOR TO PREVENT IT, WE CAN PROPERLY UNLOCK IF IT HAPPENED! NON EVO DOES NOT HAVE COMPONENT PROTECTION SO YOU CAN CONNECT ANY UNIT, IT WONT WORK BUT AT LEAST IT WONT BRICK IT.
All in all nbt unit is very nice complicated masterpiece from HK BMW, AND YOU ASKED FOR IT!!! WE ALL WANT HIGHLY SOPHISTICATED TOYS IN YOUR CARS, OTHERWISE YOU CAN NOT COMPETE WITH OTHERS, SO DON’T BE SURPRISED WHEN DEALER ASKS 2500$ TO REPLACE YOUR UNIT!!!!!

NBT-ENTRY WITH 6” SCREEN UNITS WITHOUT NAVI OPTION 609

NBT-ENTRY 2012-2016 WAS INSTALLED IN CARS WITHOUT NAVI 609 OPTION
ITS SIMILAR ARCHITECTURE BUT HAS ONLY ONE CPU RUNNING QNX
THEY DO FAIL, AND 99% ITS STUCK BMW LOGO REBOOTING
UNITS MUST BE CODED WITH FSC UPLOADED
WE DO REPAIR THEM AS WELL

NOW LETS TALK ABOUT NBT, NBT EVO, NBT ENTRY REPAIRS AND MAIN SYMPTOMS!

NBT ENTRY SINGLE DIN 2012-2015, they usually fail like this:

-BMW LOGO stays on the screen

NBT ENTRY UNIT FAILED, BMW LOGO STUCK AND REBOOTING…

-rebooting and other abnormalities

cheapest price online is $1400 and you will have to program it to your VIN, which is not very easy, while after repair it contains all you fsc data (sat radio) and coding already, so our $585 is pretty low…. so if you buy used or new, you will lose Satellite radio and other things, remember they all look the same, but part number matters: some support rear camera, some don’t, some support fiber optics, some don’t. So the best option is our inexpensive repair with 1 year WARRANTY!

BMW E65 E66 Rolls Phantom REMOTE START DIY INSTRUCTIONS

4 Replies

We are happy to introduce our first custom designed unique remote start module. I think everyone knows what remote start is and why you need it (of course you can survive without it), but here are few reasons:

Engine warm up: Did you know why BMW shows warm up line on your tachometer and they don’t want you to rev engine (DME is coded to reduce RPM before it warms up) to avoid bearings failure due to poor lubrication???? it is always good to warm up your engine and transmission before driving especially in cold weather. All moving parts of your engine will benefit from better warmer oil temps. Engine oil has much better lubrication specs when warmed up. Some mechanics will tell you its OK to drive right away, but its not true and people have no idea how oil works, no wonder why commercial trucks and cabs can get up to 1mln miles or more out of the engine. The worst wear and tear happens on the first cold start. Every cold start~ roughly 5000mls engine life and even more for diesel engine due to higher compression ratio.
Interior warm up or cool down in hot or cold weather, it will also defrost your windows and mirrors quick, so you don’t have to wait and put yourself in danger due to poor visibility etc. With extra module you can even schedule starts every day and check status of your engine and shock sensors. Most convenient feature in hot climate areas. Imagine you parked your car in Miami or Houston 110F +40C weather and how nice it is to enjoy cooled down interior and your leather seat is not frying hot anymore. Will also prevent leather wear and tear if you keep interior ventilated in the summer. You can schedule remote starts every hour or so. Imagine how much leather interior costs in 760li or Rolls Royce Phantom?

If you drive short distances it will recharge your battery at least for extra 15-20 mins.

Here We will describe how to install remote start module on any BMW e65/66/RR. Some people say it might be very complex, in fact its very easy and if you can replace a light bulb in your car, you can install this module yourself. This module was custom designed&built by us, so you will not find any solution anywhere else at least yet and its quite inexpensive, only 350$ shipped. Some people ask why is it so expensive? Well it depends what to call expensive: remote start HONDA CIVIC OR SUCH will cost you 300-400$ installed and you will have extra bulky remote and its not high tech by any means and installation is 100 times more complex (YOU NEED TO CONNECT BRAKE SWITCH, DOOR SWITCHES, ETC AND ITS ALL MECHANICAL CONNECTIONS) than our module AND NOT SAFE, BECAUSE IT OPERATES HIGH CURRENT RELAYS AND IF INSTALLATION DONE UNPROFESSIONALLY YOU MIGHT BURN YOUR CAR, UNLIKE OUR MODULE IS FULLY INTEGRATED INTO ALL BMW MODULES AND IT DOES NOT OPERATE ANY HIGH CURRENT RELAYS OR SUCH, YOU CAN SEE HOW THIN OUR WIRES ARE, AND OUR MODULE COMMUNICATES USING 8 BIT MICROPROCESSOR AND FULLY PROGRAMMABLE AND TALKS TO CAS AND IHKA MODULE THE WAY BMW DESIGNED AND YOU DO NOT NEED TO BUY EXTRA REMOTE AND HIDE IT IN THE CAR (REDNECK REMOTE START SOLUTION). SO OUR REMOTE START CAN BE CALLED FACTORY REMOTE START MODULE, SINCE IT WORKS ON TOP OF THE CAS MODULE. AND ITS VERY VERY SMALL AND CAN BE HIDDEN VERY EASY NEAR CAS MODULE.

Tools needed:

Torx T25 screwdriver
Some sharp pick tool or scalpel
***BMW NCS &INPA installed on your laptop with OBD DCAN cable
Pair of good hands:)

*** We will provide free coding if you don’t have equipment or experience, plus we can code extra options if needed (open windows from remote, LED replacement coding so no errors on the dash, fold mirrors from remote)

Installation process can be divided in 2 easy steps:

INSTALLATION & CODING/PROGRAMMMING

INSTALLATION ONLY 6 WIRES (4 posi taps and 2 insert contacts):

Disconnect negative wire from your battery as a precaution, though its not necessary
Remove plastic panel on top of the climate control module, it simply pops out. Use some flat plastic panel remover tool or credit card. Unscrew (1) 4 T25 screws holding central vent. Gently Push central vent out of the panel, Disconnect central vent sensor connectors. Check pictures:

Remove CAS and IHKA connectors. Check pictures:

Remove actual pin connectors from the housings. Use some sharp pick tool or scalpel or knife to release tabs on each connector. Each connector has special direction lock so you can’t install them wrong and has numbers on it. Check pictures:

Find appropriate wires from remote start module connector and connect them according to this diagram. I recommend installing POSI TAPS connectors further away from housings, so you can close it easy. Just move down factory isolation tape for some extra space. You need to insert 2 contacts female pins and tap 4 wires into existing wires. Please make sure you follow this diagram (click to enlarge):

Once all wires connected properly, please connect actual remote start module. If everything was done correctly, you should see emergency blinker flashing 3 times. It will only do it once, after you connected the module. This means everything was connected properly and module can talk to your CAS module, this is very important step. You cannot proceed if you didn’t see flashing. To confirm, you can disconnect it again and connect it, so you see the confirmation flashing again. Now Emergency blinker will be used to program your keys and features.
*** Blue wire from remote start module can be used to add additional remote start module to extend the range or it can be used with GSM module, so you can start it from anywhere in the world where cellular network is present. By default its programmed to start the vehicle once +12V is present on this wire. You can install Viper car alarm with SMARTSTART module, this way you can start it anywhere with cellular network. This is additional feature and not supported in all countires.

CODING&PROGRAMMING (we can code it remotely if you don’t have equipment)

Assuming everything was installed correctly in the first step, we need to code CAS module to accept commands from our remote start module. This very important, because it will not accept anything from our module otherwise.

If battery replacement was never registered, you should register it using INPA or ISTA. It might not start the engine if battery is weak or not registered

Add $539 and code CAS and IHKA modules, for American and Canada market you need to change FA code as well. Note: if you have WEBASTO heater and you would like to also start your heater remotely, please add $536 option as well. Last number of the FA code should be changed from 3 to 1.Example FA code with added $539 option and changed last digit from 3 to 1: E65_#0906&U6SW%0475$1CA$229$248$252$255$2EA$2VB$302$316$319$322$323$330$358$403$415$416$423$430$431$438$441$442$451$453$456$464$470$488$494$496$508$521$524$534$539$609$620$645$655$672$677$691$697$760$845$850$853$925$992$9AA*HL81-LEDE

Now after you coded CAS and IHKA modules with NCS Expert, our remote start module can talk to CAS and IHKA, so you have to program remote start module to your CAS, by using this technique shown on the video or use diagram below. Door locks MUST respond accordingly just like on the video. If you didn’t see this confirmation, it means you didn’t count pauses, or CAS hasn’t been coded with $539 option and last number hasn’t been changed. You can not proceed if you didn’t see module pairing confirmation with door locks and eergency blinker!

Now after remote start module has been paired successfully with your CAS module, we need to store our factory remote keys in the remote start module memory. It supports up to 6 remotes. Please follow the video to pair your factory remotes with the module. If you didn’t see this confirmation, it means you didn’t count pauses between pressing buttons, or CAS hasn’t been coded with $539 option and last number hasn’t been changed. You can not proceed if you didn’t see module pairing confirmation with door locks and emergency blinker!

If all steps went through successfully and assuming factory remote works good and alarm beeps once after you lock it , you should be able to start your vehicle by pressing lock button on your remote 3 times and stop the engine by pressing it 2 times. By pressing lock button 5 times you can start WEBASTO aux heater if your car equipped with it. Every second press of the lock button will be confirmed by turn signal blinkers, so you know it accepted your commands.

Congratulations, everything was done properly. If you have doubts you can code it, we can always help remotely and send you the equipment, plus you will get free full diagnostic (300$ at the dealer by the way). 300$ deposit will be refunded upon receiving the equipment. Do not hesitate and contact us by email or call (415)323-3412.

Conditions it will not start the engine:

it didn’t beep once, after you locked your vehicle. Possible reasons: Hood open or hood switch faulty (you can disconnect it, this way your car thinks it is always locked), any door open or trunk.
Low fuel level in the fuel tank. Less than 60mls range or 100km. Make sure fuel level sensor is working correctly
Battery is weak or not registered

This remote start is very sophisticated and incorporates all safety features built into the CAS from factory:

Will not let anyone drive it without remote key. If you don;t have comfort access you will need to insert the key in order to switch gear selector. Otherwise it will not let you select gears or rev the engine.
It will turn off itself after 15 minutes, if no one opened the car.
Automatically sets up 72F temperature with AC to cool down or heat up interior.
Will not let anyone with remote key operate any controls inside the vehicle, otherwise it will shut off everything.

BMW THERMOSTAT PROBLEM AND SOLUTION. THE MOST IMPORTANT THING ON THIS SITE!!

23 Replies

THIS POST AFFECTS ABSOLUTELY ALL BMW GASOLINE ENGINES AFTER 1995! M54, M62, M62TU, N62, N63, N52, N47, N63TU AND OTHERS, OR WHY IT IS A VERY GOOD IDEA TO LOWER RUNNING TEMPS!

Why I called it BMW THERMOSTAT PROBLEM? What is wrong with that simple part in BMW?? It looks like a well made thermostat and lasts for a while. Obviously nothing wrong with thermostat quality, in fact its a very good quality part made by BEHR.

So here is the thing. Since 1996 BMW introduced 105C MAP DME controlled thermostat for V8 and 97C for Inline 6 cylinders, which can be controlled by DME when needed.

So here is what it is, Nothing crazy here- just a heater, so DME can heat it up and open it earlier than thermostat is calibrated. Lets say it can open it at 95C versus 105C mechanical specs.

Sounds like a cool idea:

-Run your engine hotter in the city or low engine loads 105-110C to get better mpg and less emissions with REDUCED POWER OUTPUT, because they think you don’t need it in the city, so to save mpg. May be a good innovative idea.

-run it cool on the highway 90-98C to get full POWER OUTPUT.

BUT HERE IS A DOWNSIDE, OR A SMART BMW MOVE??:

You cannot raise the temperature to 110C without raising coolant pressure (otherwise it will start boiling), So they installed 200 (2.0 BAR) radiator cap. So imagine in the city your cooling system is under serious pressure. Compare it to Toyota 1.0-1.3 BAR max! But they run 87-90C simple conventional thermostats, without any innovations like DME controlled THERMOSTAT, and most Toyotas don’t have any serious issues at least 7-10 years, unlike BMW where you get cooling system failures all the time! Exploded, cracked coolant tanks, hoses, gaskets and other cooling system parts. Any tiny leak will lower cooling system pressure and you will get micro boiling, where OEM 105C thermostat can not open due to that micro boiling and you can experience ALWAYS COLD LOWER HOSE SYMPTOM I’M SORRY BUT IT WASN’T THE CASE FOR 1970-1995 BMW ENGINES WHERE THEY USED 85-95 TSTATS.
Your engine runs at 105-115C will raise oil temperatures to up o 120-130C which is a lot, though they say synthetic oils can easily withstand it. They forgot to tell you all rubber parts don’t like this temperature at all, and rubber becomes dry or even plastic very early: VALVE SEALS, VALVE COVER GASKETS, VALVE COVERS GET WARPED VERY EARLY, ALL RUBBER GASKETS IN THE ENGINE (OIL PAN GASKETS, ALTERNATOR BRACKET GASKETS, SPARK PLUG PIPE GASKETS, VAUUM PUMP GASKETS, VANOS SEALS AND OTHERS). There is a mechanic’s favorite joke: -IF BMW DOESN’T LEAK ANY OIL, IT MEANS THERE IS NO OIL LEFT!!!!! I’M SORRY BUT IT WASN’T THE CASE FOR 1970-1990 BMW ENGINES , WHERE ENGINES WERE THE MOST RELIABLE! NOW IN 2016 YOU CAN BUY 5YEAR OLD BMW AND START REPLACING ALL GASKETS. DO YOU KNOW HOW MUCH IT COSTS? VALVE SEALS ON V8 MIGHT COST YOU 3000-8000$ EASY! That’s why you can get 5 year old V8 BMW for “cheap”. THERE IS NO CHEAP USED BMW:) IF YOU GOT IT CHEAP, IT MEANS THEY GOT RID OF IT NOT TO DEAL WITH REPAIRS. ALSO OIL LEAKS WIL LDESTROY YOUR SUSPENSION VERY QUICK!
High running temperatures 110+ will get you small detonation, but since BMW has knock sensors, you will not hear it, because DME will retard timing in milliseconds, so everything sounds ok, but engine power is reduced! Try to drive your car in the morning when cold and compare it to traffic city driving when hot. If you Have turbocharged engine you will notice a huge difference, because high temps will affect inter cooler cooling as well.
High running temps can affect cylinder walls cooling unevenly, causing piston rings to lose flexibility and therefore its function, they also call it frozen piston rings (loss of compression, high oil consumption). Thus you might get high oil consumption even on low miles vehicles, but BMW will tell you it is ok AND WITHIN SPECS to have 1QT/1000MIES! N63, M54, N52 ARE THE WINNERS HERE:) OTHERS CAN BE FIXED WITH NEW VALVE SEALS.
TRANSMISSION: Since transmission has no separate cooler and connected directly to engine radiator, it also run hotter then it supposed to, and if you have always cold lower hose symptom, I can tell your tranny runs way too hot and way over 82C specs, sometimes I see 115-120C temps, running with these high temps will destroy any transmission internals pretty quick. Even 82C is somewhat high, but still okay. best temps 70-80C for this tranny.
In M62B44TU, M62b44 we see lots of issues with chain rail guides broken after 100k-150k, but we do not see this problem on M62B44 E31, where they run conventional 95C thermostat, BUT THE ENGINE IS 100% the same, and this exactly the same engine lasts at least 2x times longer compared to the one with 105C MAP thermostat (E39/E38/E53/RANGE ROVER HSE), needles to say their cooling system lasts 20 years easily. You can ask e31 owners about their experience and how often they replace chain rail guides and compare it to all other running 105C tstat in all other BMW models except E31 of course. My e31 1994 with M60 running 85C tstat had original cooling system, when i bought it in 2012! All parts were original (coolant tank, tstat, water pump, hoses), it had infamous NIKASIL problem (cylinder walls cororoded), but other things were in perfect shape after 20 years and 150kmls! WHICH MEANS BMW QUALITY IS SUPERIOR TO OTHER BRANDS IN SAME CONDITIONS, BUT PHYSICALLY THEY CAN NOT WITHSTAND THESE HIGH TEMPERATURES AND PRESSURE.

So as you can see BMW innovative thermostat design might sound innovative, but personally I believe it is done to SHORTEN ENGINE AND TRANSMISSION LIFE, SO YOU BUY A NEW CAR EVERY 3-5 YEARS. THATS THE REASON 10 YEAR OLD BMW V8 COSTS LESS THAN TOYOTA CAMRY SAME YEARS AND MILES!

SO TO SOLVE THIS PROBLEM WE CAME OUT WITH INNOVATIVE SOLUTION TO RECALIBRATE ORIGINAL THERMOSTATS AND LET IT OPEN AT 87-90C, VS 105-110C, ITS ALMOST 20C DIFFERENCE AND IT IS HUGE DIFFERENCE, BECAUSE THIS WAY WE CAN REDUCE COOLING PRESSURE TO 1.0-1.3 MAX JUST LIKE ALL NORMAL JAPANESE CARS. ALL RUBBER GASKETS WILL LAST AT LEAST 2X LONGER, BECAUSE AT 110 RUBBER DRIES OUT VERY QUICK. ABSOLUTELY NO ERRORS AND YOU WILL FEEL THAT YOUR CAR RUNS STRONGER IN THE CITY, AND GAS MILEAGE IS ALMOST THE SAME OR EVEN BETTER VS OEM TSTAT. AFTER TESTING IT FOR 4 YEARS I CAN TELL, IT DOES NOT CAUSE ANY PROBLEMS TO THE ENGINE, BECAUSE EVEN WITH OEM TSTAT YOUR CAR RUNS 90-93 ON THE HIGHWAY! WE HAVE 85-95C THERMOSTATS FOR ALMOST ALL BMW ENGINES STARTING FROM 1995.

I UNDERSTAND, LOTS OF YOU WILL SAY BMW ENGINEERS DESIGNED IT, AND WHO ARE YOU TO SAY THAT? WELL, I HAVE MECHANICAL ENGINEER DEGREE AND OUR PROFESSOR ALWAYS TOLD US, THAT 90-95C IS THE BEST RUNNING TEMPS FOR THE ENGINES, EVERYTHING HIGHER GETS YOU DETONATION RISKS AND NOT MAKE MUCH SENSE TO GET A LITTLE BETTER MPG…

HOW ELSE TO EXPLAIN HIGH ENGINE RATE FAILURE IN BMW COMPARED TO SIMPLE TOYOTAS AND HONDAS?? EVEN KIA IS WAY MORE RELIABLE THAN MODERN BMW, THEY ALL RUN 82-87C TSTATS WITHOUT ANY INNOVATIONS. MERCEDES ALSO RUNS IT COOL 90-95 MAX, THEY HAVE OTHER ISSUES, BUT COOLING SYSTEM IS RELIABLE AND NOBODY REPLACES VALVE SEAL GUIDES AFTER 40-60K MILES ON THEM, NORMAL ENGINE CAN EASILY LAST 200KMLS ON ORIGINAL VALVE SEALS, AND SAME PARTS SUPPLIERS USED FOR BOTH BRANDS BY THE WAY.

ALL BMW M ENGINES RUN LOWER TEMP 79C THERMOSTATS, AND THESE ENGINES ARE INNOVATIVE FOR SURE AND THEY LAST MUCH LONGER AND KEEP THEIR VALUE :

S54 RUNS 79C
S62 RUNS 79C
S85 RUNS 79C P/N:1153783615
ALL DIESEL ENGINES BMW RUNS AT 88C AND THEY EASILY LAST UP TO 500k MILES WITHOUT ANY LEAKS OR FROZEN PISTON RINGS (THEY HAVE EGR PROBLEM (which can be deleted) BUT ITS NOT RELATED TO OUR TOPIC)

SO APPARENTLY THERE IS NOTHING WRONG TO RUN THESE ENGINES COOLER, JUST LIKE ALL OTHER NORMAL CARS DO. AS YOU UNDERSTAND BMW EVOLVED A LOT SINCE 1995 AND USED BMW CARS DEPRECIATED CRAZY SINCE THEN, ONLY BECAUSE OF RELIABILITY ISSUES. COULD BE COINCIDENCE??? I DON’T THINK SO, I KNOW TONS OF PEOPLE WHO DUMPED THEIR CARS FOR NOTHING, BECAUSE OF THE REPAIRS. IMAGINE NEW 7″ COSTS 100K AND 10 YEARS LATER YOU CAN GET IT FOR 10K OR LESS ALMOST CAMRY PRICE! SOMEONE SAID BECAUSE BMW USES LOW QUALITY RUBBER GASKETS, IT NOT TRUE, THEY USE TOP NOTCH QUALITY CONTROL.

I HIGHLY DOUBT BMW CAME UP WITH THIS 105c TSTAT JUST TO SAVE MAY BE 1-2% MPG, HOW COME OTHER CARS DON’ T DO IT???? IT IS MUCH EASIER TO SELL LOWER MPG CAR, RIGHT??

ANYWAYS, IT IS UP TO YOU TO BELIEVE IT OR NOT, BUT SIMPLY TYPE “BMW LEAKING OIL OR COOLANT N62, N63” IN GOOGLE AND THINGS WILL LOOK VERY DIFFERENT FROM OTHER CARS MAINTENANCE.

INTERESTING STORY:

One friend of mine bought 750li 2007 with 103k in okay condition with ONLY check engine light on, so when i inspected it, i was pleasantly surprised:

engine had zero leaks from valve covers and valve seals were in okay shape!!!! at these miles it is almost 100% valve seals are gone and valve covers leak along with upper timing covers and other things!! so no oil leaks
cooling system had ZERO new parts installed, everything was in okay shape, all hoses original and no issues at all. even coolant tank had no cracks, which is very rare. so all components lasted 100k!!! and still lasting
THE ONLY CHECK ENGINE LIGHT INDICATED JAMMED THERMOSTAT, WHICH IS NORMAL BECAUSE THEY DON’T LAST FOREVER. SO PREVIOUS OWNER WAS CHEAP AND NEVER TOOK IT TO BMW AFTER WARRANTY EXPIRED!!! BUT THIS JAMMED OPEN THERMOSTAT (FIRST OCCURRED AT 50KMLS) LET HIS CAR RUN AT 80-90c MAX, BECAUSE IT WAS NEVER 100% CLOSED DUE TO WEAR AND TEAR, SO THIS IS WHAT SAVED HIS CAR FROM EXPENSIVE REPAIRS. ABSOLUTELY ZERO NEW PARTS WERE INSTALLED ON THIS ENGINE AND ZERO LEAKS ANYWHERE! CAR RAN PERFECT!

SO HE REPLACED THERMOSTAT AND NO MORE ERRORS, BUT IN 3 MONTHS HIS VALVE COVERS STARTED LEAKING BADLY….. 5 MORE MONTHS LATER HE GOT INFAMOUS ALTERNATOR BRACKET LEAK (800$+)

THAT’S WHY WE DESIGNED THE WAY TO RE CALIBRATE ORIGINAL THERMOSTATS TO RUN AT 90-95C. NO ERRORS WERE THROWN, ENGINE RUNS PERFECT SINCE 2013 AND NO NEW LEAKS.

WE CAN RE CALIBRATE ANY BMW AND OTHER BRANDS THERMOSTATS, YOU CAN EMAIL US WITH YOUR QUESTIONS.

NEW ORIGINAL RE CALIBRATED THERMOSTAT FOR N62, N63 WILL COST YOU ONLY 199$ (FAST&FREE SHIPPING INCLUDED), WHICH IS THE BEST UPDATE FOR YOUR HOT RUNNING ENGINE. SOON IT WILL BE POSTED ON EBAY, SO IF YOU FELL MORE COMFORTABLE YOU CAN BUY IT FROM THERE, BUT ITS A LITTLE EXTRA DUE TO EBAY FEES. ALSO WE RECOMMEND INSTALLING NEW HEATER VALVE EVERY 5-7 YEARS (standard symptom-no cabin heat or one side is hot and another is barely hot, also it might cause overheating as well, because you cannot bleed the air if tat heater is partially clogged). If everything is good and no leaks i recommend replacing: thermostat, heater valve, radiator cap. With this 90C thermostat you can easily install 140 (1,4 BAR) cap from diesel engines, because pressure is reduced due to reduced boiling point, which is a good idea, since you do not need to build high pressure anymore, though with 90C thermostat it will rarely get to that point even with stock 200 cap. All bmw diesel engines run 140 (1,4 BAR) caps, same thing with old M20 engines, they run similar temp 75-80C TSTATS or even lower. As you know those old engines could last 500kmls easy, isn’t it interesting coincidence: the lower tstat is, the more reliable engine is? You can try our thermostat, and if you are not happy you can return it for a full refund. In most cases people respond with better torque and throttle response after installing our thermostats. Obviously you noticed your BMW runs better before 100C and becomes weaker after 100C.

BMW F01/F02/F07/F25 AMPT70 AMPH1 AMPTLR13 LOGIC 7 AMPLIFIER REPAIR 2007-2019

6 Replies

$550 Any BMW fiber optic amplifier 2002-2019 except B&O amplifier.

In this article we are going to describe another next generation LOGIC 7 amplifier, which can be found on lots of BMW vehicles: F01/F02/F07/F04/E71/e70/e64/e64 and others, usually it says on it : AMPT70 (E70/E92/E63/E64) or AMPH07LR02 (F01/02 type)

Even though they have lots of different part numbers, but in reality this is the same amplifier, the only difference is coding, so based on the type of vehicle, this amplifier is coded to support different speaker setups and crossover settings. THIS IS HOW IT LOOKS LIKE:

This amplifier works the same way as first generation logic 7 amps was:

Head unit or CIC sends digital sound data over fibre optic network called MOST, then amplifier receives it, converts to analogue signal and powers up 9 channels in your car and you can hear high end quality sound without any noise or very low noise compared to standard analogue amps.

This amplifier compared to previous LOGIC 7 generation has lots of advantages:

CLASS D
MORE POWER OUTPUT 600W
BETTER QUALITY BUILT BY LEAR
NEWER MORE RELIABLE CHIPS USED
SOUND QUALITY IS MUCH HIGHER
LESS POWER CONSUMPTION
LESS HEAT PRODUCED

Main problems with this amplifier:

NO SOUND AT ALL, SUDDEN LOSS OF SOUND
CRACKLING SPEAKERS
NO COMMUNICATION WITH THE AMP
LOW VOLUME AND WEAK POWER
NO DOOR CHIMES, NO SOUNDS AT ALL

SO GOOD NEWS WE CAN REPAIR THESE AMPLIFIERS WITH A GREAT SUCCESS. Basically if your amp looks like the one on the pictures, we can fix it. These amps you’ll find in these BMW models:X5, x6, z4, m3, f01, f02, e92, e64, e63 and may be others. Part number is not very important, because we repair them all as long as they look similar to the pictures here. On older BMW it was called individual amplifier, so higher level than just logic 7 options, usually found on top vehicles, like M3, M5, X5M, M6 and others.

Standard symptoms:

-no sound at all

-crackling speakers or sub woofers

-no communication

-other audio issues

After repair you don’t need any coding, it will be plug and play.

Frequently Asked Questions:

1. HOW DOES IT WORK?

-SIMPLE. YOU REMOVE YOUR AMPLIFIER AND SEND (FITS REALLY WELL INTO USPS FLAT RATE PRIORITY BOX 12$) IT TO US AT THE ADDRESS BELOW. IT TAKES 1-2 DAYS PLUS SHIPPING 2-3 DAYS MAX. Also write down transaction 550$ PayPal or ebay id on the amplifier, so we know all details and where to send it back.

2. HOW DO I KNOW IF MY AMP IS BAD?

-BASED ON SYMPTOMS AND DIAGNOSTICS. USUALLY NO SOUND MEANS AMP FAILED OR IF SPEAKERS DON’T SOUND RIGHT. IF WE GET YOUR AMP AND IT APPEARS ITS IN GOOD SHAPE WE ONLY CHARGE 50$ DIAGNOSTICS FEE.

3. DO YOU TEST THEM?

-YES WE STRESS TEST ALL THE AMPS PRIOR TO SENDING BACK

4.WILL IT LAST?

-YES IT SHOULD LAST SIMILAR TO BRAND NEW AMP, BECAUSE WE INSTALL ORIGINAL OEM PARTS. CHECK OUR REVIEWS, WE REPAIRED 1800+ AMPS SINCE 2011.

Also we install more powerful power chips, so it can sustain higher current ratings.

5. I HAVE DIFFERENT SYMPTOMS, CAN I CALL?

-IF YOU DIDN’T FIND ANSWERS HERE, CALL OR EMAIL HERE

415-323-3412

6. How does the warranty work??

-simple. If something happens to the amp, but without physical damage or water damage, you can send it back, all we need to know is eBay or PayPal transaction id, this is how we know all the info: when warranty starts, model of the amp and serial number and what has been done to it.

7. Is it safe for my car?

-absolutely. We install oem parts, so there is no difference made to the amp internals.

8. Is it legitimate business?

-yes it is, we’ve been around since 2009 fixing amps. You are fully protected by PayPal and eBay policy. Which means you can always get your money back if something didn’t work out. So far we repaired 1900+ amps, we work with dealers all over the world but mostly within USA.

9. Why is it so much to repair it?

-well, this amp is fully digital and has nothing to do with old school amps you can buy new for 100$. Parts are expensive and we use expensive equipment to work on them, plus we provide 1 year warranty, which costs us a lot as well. In some cases amps come water damaged, which makes repair way more complex or not repairable!!

NOTE: additional fee might apply in abnormal cases like water damage or burnt pcb

10. Why would I pay 550$ if I can find used amp for 300-400$??

– well, for a few good reasons:

A) we install new oem parts which usually go bad on these amps with years, so it should last longer than used amp more likely it’ll last like brand new one.

B) this amplifier has your car VIN number coded. so you will not need any coding, because you will get your amplifier back which was coded to your car from factory. Coding is not that simple, so buying used amp will not be plug and play. Bmw dealer will not program used amp or any other used part to your car, only new parts will be installed and coded at the dealer, which means it might cost you up to 2000$ to install a new amp correctly. In our case you DON’T NEED TO SEE ANYBODY, which means you will spend only 550$ period.

BMW ENGINE LAG PROBLEM

2 Replies

BMW N62 GAS PEDAL ENGINE LAG!

On BMW N62, N63 and other engines especially e65, e66, e60, e63, e64 series most likely you might experience some gas pedal lag delay or uneven power delivery at lows. It feels like you press on it and engine barely revs from lows or it revs, but you have to press it harder to feel it. Assuming engine and tranny do not have any problems and all other components run as they should, I mean no vacuum leaks, all sensors read correct values etc, but still it feels like gas pedal is slow at lows, usually in the city driving. Funny part BMW will tell you its normal lag because of drive by wire nowadays standard, though there was no delay on m62tu engines with similar drive by wire gas pedal back in 1999. Lots of people buy some magic gas pedal boosters 200-300$, but they should understand, that this booster simply sends 2x signal to DME (engine brain),so it basically feels like you press 2x harder. This method (if you call it a method) is not a good one for a few reasons:

-it will make your car less smoother or some say it fells jerky

-not safe, you can easily rear end someone in the city

-premature transmission wear and tear

-overall more stressful for the engine and tranny

-higher gas consumption

-overpriced 200$+

So we have been looking for a solution for a while and looks like we found it!!!

and its all original BMW OEM. You simply need to replace your gas pedal assembly with the newest one they sell at the dealers or online, but make sure they sell you the newer design, because newer pedal assembly is way better and has newer chip built in, also it has newer pedal design, so it wont get sticky if dirt or water gets there. You will be really surprised, that the lag will be gone and bmw will perform like it should without any lag from lows and overall will make it fell much smoother. Look at these pics:

newer part number is: 35426859999

you will find this pedal installed on the newest BMW F series

you can get it form the dealer or online, just make sure they sell you newer design only, because lots of sellers still have old pedals in stock.

newer gas pedal design:

older gas pedal design:

It is very easy to remove it, just remove plastic cap, unscrew the metal screw 2, and then disconnect a connector. Install a new one and done! you can reset engine adaptations, but not very necessarily, it will work as is.

Basically BMW updated gas pedal design for that reason, but of course they didn’t recall it, so they know this problem really well, otherwise why they completely redesigned it??

This modification will work on any BMW with similar part numbers.

BMW E65, E66, E60, E63, E90, E92, E93, E64, E87, E53, E70 AUX PORT MOD MODIFICATION

2 Replies

Yes, it is very annoying, that BMW decided not to install aux port by default in our vehicles before 2007. In this post let’s find out what you need to get for AUX port in your bimmer.

E65 BMW 750I, 750LI, 760LI, 745I, 745LI, 730I, 730D ETC.

If your car is pre 2007, and you don’t have aux port in your idrive and neither you have aux port in your glove box- you are not in very good shape. To say the least its the hardest bmw body type if you decided you need aux port! Why? Because ask unit cd player and pretty much all multimedia modules in this car are digital, and there is no analogue signals anymore, and aux port signal is analogue, so common sense tells you need to convert it to digital bmw e65 signal in order to get sound from your sound system, doesn’t sound easy at all to say the least.

So here are the options:

BMW E65 FACTORY OEM AUX PORT INSTALLATION. DO NOT EVEN THINK OF BUYING BMW OEM AUX CORD JUST BECAUSE SOMEONE SAID ITS SO SIMPLE: BUY THE CORD 5-75$ CONNECT OT THE BACK OF YOUR ASK UNIT AND DONE??? REALLY? YES, CORD WILL FIT IN THERE AND THAT’S IT HERE- YOU WILL NOT GET ANYTHING WORKING APART FROM THAT GOOD SIDE YOU HAVE USELESS AUX PORT IN YOUR CAR. WELL, HERE IS WHAT YOU NEED:
1. IF YOUR CAR IS PREFACE LIFTED 2002-2005 BMW 745I, 745LI, 760LI, 730I, 730D, THEN YOU NEED NEWER TYPE MMI SCREEN FROM 2006-2008 MODELS PLUS NEWER 2007-2008 ASK UNIT CD PLAYER. AND AFTER THAT YOU HAVE TO CODE BOTH TO YOUR CAR USING NCS EXPERT BMW PROGRAM TO ENABLE AUX INPUT IN MMI SCREEN (IF SCREEN CAME FROM 2006 CAR) AND CODE ASK UNIT TO WORK WITH YOUR TUNER AND OTHER MODULES. WHY? BECAUSE EVERY CAR HAS DIFFERENT OPTIONS AND FOR EXAMPLE RADIO TUNER WILL NOT WORK WITH NEWER ASK UNIT IF NOT REPROGRAMMED OR RECODED, ALSO SOME CARS WERE EQUIPPED WITH L7 TOP HIFI SYSTEM VS STANDARD HIFI SYSTEM, THAT’S WHY THOSE MODULES HAVE TO BE CODED. AND ONLY AFTER ALL THESE PROCEDURES YOU CAN BUY AUX BMW CORD AND IT WILL WORK! ALSO YOU WILL NEED FACELIFTED WOODEN TRIM, BC YOUR ORIGINAL WILL NOT FIT ANYMORE.
2. IF YOUR CAR IS FACELIFTED 2006 BMW 750I, 750LI, 760LI, 740D, YOU ARE IN BETTER POSITION. YOU WILL ONLY NEED NEWER ASK UNIT 2007+, BC EVEN THOUGH THEY LOOK THE SAME, HARDWARE INSIDE IS SLIGHTLY DIFFERENT AND ONLY LATER 2006 (WEEK 30 AND UP)+ MODELS WILL WORK WITH AUX UNIT AND CODING MMI SCREEN TO ACCEPT AUX INPUT, THEN YOU WILL GET AUX IN THE MENU AND EASY WAY TO CHECK IF ASK UNIT SUPPORTS AUX IS TO SEE IF IT RETURNS AUX LEVEL AFTER YOU CHOSE AUX IN THE MENU. OLDER ASK UNITS WILL NOT RETURN THAT LEVEL SUB MENU.

2. NON OEM AUX PORT CAN ONLY BE INSTALLED VIA RADIO TUNER MODULE, YOU WILL GET CLEAR SOUND, AND IT WILL OVERRIDE ANY RADIO STATION. VERY SIMPLE, YOU PLUG YOUR PHONE AND YOU WILL GET CD QUALITY SOUND. IT WILL ONLY WORK IF YOU DON’T HAVE HD RADIO MODULE. WILL WORK WITH ANY E65 2002-2008. THIS IS TOTALLY DIFFERENT COMPARED TO LOW QUALITY RADIO TRANSMITTERS MODS. IT HAS NOTHING TO DO WITH FM/AM, IT WILL OVERRIDE SOUND SOURCE. WORKS VERY GOOD WITH APPLE DEVICES. IF YOU NEED HELP WITH AUXILIARY PORT INSTALLATION YOU CAN EMAIL FOR DETAILS.

ALL OTHER SERIES ARE MUCH EASIER. E60, E90, E63, E64, E92, E93, E87, E53, E70 WILL ONLY NEED AUX PORT ENABLED VIA NCS CODING AND BUYING A CABLE.

This amplifier is different than E65 Logic7 amplifier, it runs different software and cannot be installed on either. This amplifier has 9 channels vs E65 with only 5 channels. This amplifier controls all the speakers on the car, so if it goes bad you will not hear any sound in any speaker.
But not always amplifier is the problem, in some cases other modules go bad, interrupting MOST network and you will not hear any sound even with working amplifier. So here i will explain how to diagnose if it is the amplifier or something else went wrong.

This amplifier has a diagnostic LED, which will show lots of things you most likely don’t know about. Here you can see where it is located. So look at that LED, turn on the radio and look at it:

basically:
blinking yellow -check or bypass sat tuner or Bluetooth tel module
no yellow– amp is bad
steady yellow but no sound or bad sound- amp is bad

1. Steady yellow means its getting input fiber optic signal from the head unit (CCC or CIC) and output signal travels to the head unit correctly through other units , so you should hear the sound in most cases, but rarely it also could be some software glitch with CCC, when you don’t get sound with working amp. Try CCC reset.
2. Blinking yellow means AMPLIFIER IS WORKING and getting input signal from the head unit, but output signal is somewhere lost due to the next bad unit in the loop. So you just need to find a bad unit and either bypass it or replace it with a working one. Most common units to fail are: Sirius satellite unit, Bluetooth telephone unit

No Yellow LED, but you can see blinknig red LED deep inside most likely means 3 things:
1. amp is bad
2. no power getting to the amp check last 2 thick wires red and brown 12V should be present always, otherwise check fuses in the trunk.
3. No fiber optic input getting into the amp from head unit, but in this case you should see a red LED on for 15-20secs, this means amp is waiting for a signal and if no signal present it will go to sleep mode. Easy to check, you should see a blinking red LED in the CAR CONNECTOR with the amp fiber optic connector disconnected. If its blinking it means head unit is sending signal to the amp and amp CPU has to accept it and send the output signal back to other units and head unit eventually. Rarely, But if no red led present in the connector it means no signal is coming from the head unit due to either bad head unit or some fiber optic wire damage. If you remove head unit and you see a red light blinking, you should see the same blinking at the amp connector.

So basically you should get steady yellow LED at the amp, which will indicate the network is working, bypass not working modules and if amp is good you will get sound back to your car!

These amps are much better design compared to E65 design, but they still go bad due to following reasons:

Water damage especially on convertibles 6 series, almost always we see this problem: It happens when water drainage pipes get clogged up with dirt and thanks to smart design all water leaks onto the amp and other units. Please always clean those pipes with compressed air and some soap. On 3 series we see rear taillight bolts getting loose and therefore it leaks water inside.
Actual CPU failure or other things go bad inside the amp. We can help in this case, but can not guarantee 100% success, usually we see 60-70% success rate vs 90% e65. Good thing these amps are quite cheap on Ebay or junk yards, or new from the dealer 1200$.

HOW TO BYPASS NON WORKING MODULE??? EASY! GET THIS P/N FROM ANY BMW DEALER 61136917541, YOU CAN GET IT ONLINE FROM ECS TUNNING ECS TUNNING FIBRE OPTIC JUMPER. YOU HAVE TO REMOVE INNER PART WITH SOME FLAT SCREWDRIVER OR A KNIFE, YOU CAN ALSO USE ZIP TIE IF YOU PLAN TO

ALL BMW M54, M52, M60, M62, M62tu, M56, N62, N62B48tu and others!! Engine Overheating? No its not a head gasket problem!

6 Replies

Ok, i decided to create this post because i see lots of bimmers running hot or even overheating. You would say nothing new here, right? Well believe it or not lots of mechanics or shops trying to resolve this problem with no luck and in the end as a final solution they offer head gasket repair, which won’t fix anything.

So here are the main standard problems, applies to any water cooled engine:

Radiator cap not sealing well or valve inside is not working anymore causing boiling in your cooling system due to pressure loss. Solution? replace radiator cap every 5 years even if its good.
Any coolant leak will create pressure loss and introduce air in the system. Make sure there is no leaks. Use Pressure tester.
Thermostat if bad, it stays open on these engines, and you usually get error code P0128 if heater inside burned or you get thermostat jammed error code. usually tstat lasts 70-100k easily.
Water pump impeller can slip or even fall apart or bearing might seize causing total failure. Good thing these engines head gaskets are very strong and can sustain serious overheating.
REPLACE TEMP SENSORS EVERY 70KMLS, THEY DO GO BAD AND SOMETIMES SHOW LOWER TEMPS THEN IT IS, ESPECIALLY WATER PUMP TEMP SENSOR, LOWER SENSOR IS KNOWN FOR O-RING LEAK, APPLIES TO ANY BIMMER.
Main engine fan (electric) is bad or fan clutch not working anymore, though even with a bad fan clutch and fully working cooling system you will not get overheating, unless you are in Dubai traffic:) AC fan is very effective even with a bad fan clutch. Since 2004 BMW uses only electric fan for both AC and engine, so if it goes bad, you will get overheating.

So, i was not going to create simple overheating article you can find anywhere, right? Its gotta be unique on this site! Here we go:

So what to do if there is no leaks and all hoses are new, gaskets etc, pressure tester confirmed no pressure loss, but engine still runs hot overheating transmission as well??? Did you know running hot will destroy all rubber gaskets and other rubber parts? Why? Because engine temps are not consistent like it was designed! Ok, here is something nobody cares about when trying to fix overheating issues:

NORMAL TEMPS FOR 6cyl=94-98 max

NORMAL TEMPS FOR 8cyl=103-108 max

TO CHECK RUNNING TEMPS YOU NEED TO OPEN HIDDEN MENU:

1) hold reset odometer button until you see the menu

2) go to 19 unlock menu (press button once) and enter (hold the button to enter) the sum of your last 5 vin numbers:

ex: last vin 23657, so sum=2+3+6+5+7=23

3) now go back to menu 7 and hold the button until you see running temps, if you don’t, it means you enter unlock code wrong:

here is a picture of running temps with RECALIBRATED 87C thermostat, these are actually really good temperatures for this and other V8 engines! It will keep your cooling system healthy and will prolong the life of all rubber gasket seals including valve seals. Moreover it will reduce detonation so you’ll get extra power in the city driving! Imagine lowering cooling pressure from 200 to 120??? 200 is what your tire pressure is. It is a big deal, all rubber gaskets run under serious stress and we see tons of exploded hoses, coolant tanks and other expensive leaks like:

wheep hole 2000$ if you install oem pipe

rear cover plate (Tranny needs to be removed)

valley pan (intake removal needed)

Soon we will offer these cooler temp tstats.

HEATER CONTROL VALVE! THIS VALVE DOES NOT LAST! RUBBER SEALS INSIDE BECOME BRITTLE, CLOGGING UP THE COOLANT CHANNELS GOING TO THE HEATER CORE! RESULT IS OBVIOUS=YOU CANNOT BLEED THE AIR OUT OF HEATER CORE=OVERHEATING! THIS ENGINE HAS SELF BLEEDING COOLANT SYSTEM, BUT IT WILL NOT WORK IF THIS VALVE IS CLOGGED.

HERE IS DISASSEMBLED HEATER VALVE FROM 2006 750LI with 98kmls. As you can see rubber seals are cracked and not flexible anymore, BUT if you have working auxillary water pump, you still get okay heat cabin, but system has air pocket, since you need very good flow when bleeding coolant system.

HERE IS THE MAIN PROBLEM: YOU SHOULD SEE A NICE RUBBER SEAL AROUND THE VALVE, BUT ITS ALL BROKEN AND THE WORST PART IT CLOGGED RIGHT CHANNEL COMPLETELY:

SO GOOD RECOMMENDATION IS TO REPLACE IT EVERY 5-7 YEARS AND START EVERY COOLANT SYSTEM PROBLEM FROM THIS VALVE REPLACEMENT. IF THIS VALVE IS GOOD YOU CAN DRIVE YOUR CAR EVEN WITH LEAKING COOLANT (I KNOW ITS NOT A GOOD IDEA), BUT YOU WILL NOT GET OVERHEATING ISSUES IF YOU KEEP ADDING COOLANT, BECAUSE ENGINE WILL BLEED ITSELF ALL THE TIME IF HEATER CORE HAS NO AIR POCKETS. REMEMBER COOLANT SYSTEM IS THE MOST IMPORTANT SYSTEM IN YOUR CAR!

SO UNTIL YOU SEE OIL IN THE COOLING SYSTEM, OR COOLANT IN THE OIL OR EXHAUST SMELL FROM COOLANT TANK, DO NOT BELIEVE IN THE HEAD GASKET FAILURE. WHEN HEAD GASKET IS BAD, YOU WILL KNOW IT FOR SURE:) V8, IS VERY STRONG ENGINE AND ITS NOT EASY TO DESTROY HEAD GASKET BY JUST OVERHEATING, DOESN’T APPLY TO STRAIGHT 6 THOUGH….
