George you deserve more recognition for your content. As a novice your tutorials make it easy to carry out work on my n52 and I've saved thousands because of it. Keep going mate

[@GeorgeAusters]

Much appreciated mate!

[@GuyWitaGun]

I need this for the n20 man😅

[@z4funkdreamer986]

The correct procedure as published by BMW is fill the reservoir until coolant runs out the bleed screw, then fully close the screw and reservoir cap, then run the water pump. So you must have your cap on absolutely not cap off It will work but is not the optimal procedure for the n52 Problem in the futur could be 2e83 code that means the pump run dry and will fail quickly This kind of electric pump have sensible impellers and hates air bubble that is why many people have failed pump few time after installation

[@mahhbad5448]

I had a stroke Tryna read this fam

[@wilowilo9462]

🤔 I don’t see any problems cap off that is why you fill the system first before you activate the electric pump

[@hamwoollard2651]

Great video man. Everything I've needed to know for my 130i, I've always found on your channel. Your content is easy to understand, and really easy to see what you're actually doing.

[@GeorgeAusters]

Glad to help!

[@martinpowell3855]

Dude you had the chocks in front of the wheels when they should been behind them LOL.

[@kingly71]

George liked it so you're prob right, but you could definitely have been wrong. It's hard to tell what the slope of that driveway is... probably slopes down to road (in which case you're right), but if the slope is away from the street then the chocks would be correctly placed. Unless a car is just gonna go rolling uphill.

newer coolant systems like the b45 b58 n20 have split cooling systems. These systems have totally separate cooling high temp and low temp and you have to use a cooling evacuation tool

Some tecnicians connects an air pump with preassure gauge and pump air into coolant sytem and waiting for preassure loose &.another testing way for blown head gasket is a chemical kit if thee is some exthaus gas into water coolant chemical's color is going to yellow that means your head gasket is blown.Do you have this kind of test kits in England?may it can help you to determine blown head gasket before removing it

[@joestinchcomb8630]

George Nice Work but you might want to make sure people understand not to attempt to drain with system pressurized. You don't want to accidentally give multiple people a trip to the emergency room from 3rd degree burns. Maybe I missed your m]ention for precaution, but it would be worth repeating.

[@marktolner2922]

I always enjoy your detailed videos - especially the anal ones like this! Thanks. Just a word of caution though and that is that anti-freeze also increases the boiling point of the coolant quite significantly and so if you run on pure or nearly pure water of any kind then your cooling system will experience a higher pressure if the usual operating temperature is more than 100 degrees C, which is the case for many BMW's (not necessarily yours though). I learnt this to my cost in my 2005 760li because even in my advanced years I had no idea of this property of anti-freeze used in cars.

Cheers Mark!

Thanks for another thorough and well thought out video, George! Great tips!! Fairly irrelevant question, if the sound padding on the inside of the bonnet (or whatever it is) is flogged, is it okay to just remove it? I noticed this car doesn't have it. Will heat affect the bonnet/paint, etc?

[@GeorgeAusters]

Fine to remove it, it's just sound deadening really

Very good video George. My name is Mo and I am a fan of yours and a subscriber from Mauritania north Africa. I have a 2010 BMW 535i f10 which has around 156.000 km on it. It only recently started making this rattling noise when accelerating. I watched the video where you change the bearing and the guibo on the center support but at the end of it you say your car still makes that noise. My question is: did you find the real source of the problem ?

a lot of people do not know that all bmw engines have a drain plug on the engine, the most of the time at the right side , on M57 its between the engine and exhaust

[@GeorgeAusters]

Not all do. The N52 doesn’t👍🏻

Yes, the N52 has a coolant drain plug on the passenger side along piston #2 channel about half way down the block. New Alu crush washer needed.

Hello George Austers! Your videos are very good and of great help to those who are professional or not. I want to record my thanks to your noble person. Now let's get to the topic of your video. On my BMW M5 E60 LCI 530i - (N52B30A) 2008/9 I had to change it due to the time of use. It was still the original (Tubo flexível culassa/termóstato - 11537544638). At the moment there was no substitute and import would take time. What did I do? I took a connection and blue PPR tube (Random Polypropylene Copolymer), which is used in compressed air systems and made it similar to the original. I'm using it even today, and the original that arrived I left it as a reserve. It was very good and met the characteristics of use. It's been in use for over 6 months now. Big hug from Brazil.

[@GeorgeAusters]

Thanks buddy, appreciate it!

Thanks George I’ve just bought a used Bmw e90 which appears to have orange coolant in. Will be changing ASAP. What’s the damage? 🤨

Hi George, Hope all is well mate. Ive bought an E88 Convertable and ive noticed that it has pink coolent. The question is do i need to be worried or is ok just to run the car as is. Your thoughts would be greatly appreciated, cheers.

I've opened it up and there's an O Ring but it's not a common size and BMW don't sell it (just the entire hose assembly).

Untill the air came from the bleeder screw..... I told him to bleed through the steps you mentioned but..... He just..... I dont know..... But he is a experienced guy and only works on German cars...... After the coolant change minimum 64 km ran.... Seems fine..... After that i opened and checked the tank and it is fulll..... Dont know wht happns❤❤

Did you use hot tap water to keep flushing through with hot engine ?

Nope just room temperature👍🏻

[@07szim]

Never Tap or Spring water. Distilled water is the best and only thing should be used.

[@GeorgeAusters]

Distilled or deionised is even better, I used deionised

[@onecookieboy]

I disagree with warming the engine to operating temp then draining it and filling with cold water and running it again and again until the water is clear. Several reasons, 1) not very safe, 2) thermal shock, the engine block retains heat and them you add cold water, bad. 3) the water pump relies on the coolant to lubricate the seals and impeller so no coolant=no lubricant=reduced life of pump, 4) you were very lucky not to get a massive airlock in the system which could have lead to head gasket failure or worse. Don't change your coolant this way.

[@seanpaul3050]

I agree. This method is just wrong on many levels. Can’t be bothered to go through all the reasons why.

[@GeorgeAusters]

I've used this method for years - never ever had an issue. When you're filling with cold water, you're filling the radiator - not the engine

[@onecookieboy]

@@GeorgeAusters I have owned an E91 with the N52 engine for 4 years now, and that is not how to change the coolant, the best way to drain the cooling system is to remove the hoses from the water pump, that almost completely drains the cooling system, I measured how much I got out, just under 9 litres, so a bit fiddly but not as risky. When you drain the radiator you are most likely draining the cylinder head as well given that the thermostat is down by the water pump so the chances of getting a big airlock in the head are high. I would say that you were lucky that you didn't damage the engine.

[@JosePalacio12]

@@onecookieboy so just remove hoses from water pump and thats it?? I had to replace my radiator so all that is removed how would you suggest i move foward for no airlock since you are saying to just remove hoses?? Im curious bc i dont want to ruin car.

[@onecookieboy]

@@JosePalacio12 Put everything together and fill as much as possible at the header tank. The E9x cars have an electric water pump and thermostat that has a bleed function. This is how it works. Put heater on full hot and adjust the heater fan to its lowest speed, have the ignition in the run position but don't start the engine, hold accelerator pedal fully down for 10 seconds and release, this starts the bleeding sequence, you should hear the pump running and there will be gurgling noises and the pump will stop and start a few times. After that, top off to the correct level, job done.

mate the color of the coolant doesnt matter lol red, green, blue or transparent it's all the same. It's just different depending of the brand.
