How to vent/bleed coolant system on BMW E60/E61 

Thank you for your comment. Glad it was helpful.

@@EliteBimmers Basically you are simply doing this to remove air after changing with fresh coolant?

@@nature10879 Yes, you are correct.

😃 appreciate your kind words!

I believe only when you flush the system. Also, if your car overheats after you add coolant you need to bleed it.

Спасибо!

No, just tu it approximately 12 minutes. It should be sufficient.

I’m not 100% sure about the engine temperature. I did it on cold engines. I think it shouldn’t be a problem if engine is warm. This method is just to siphon air from the system. You may need to add coolant if it is complete.

I hope you did by now. But mine wil get stuck on the bottom some times.

Not sure about D models.

Hello, it is possible that your battery is not strong enough. Try connecting your car to a charger. Hope it will work for you.

It is not expensive to replace. I bought not OEM one and it works great. Two years no issues.

I understand your question. It might leak when pressure will start building up.

Да, но обязательно обе крутилки температуры на максимум тепло, и сам вентилятор на минимум - на первый сетинг. И затем нажать педаль газа на 10 секунд.

@@EliteBimmers делаю так ноль реакции у помпы

@@andreipuk7818 Сложно так сказать. А если так долить, греется?

@@EliteBimmers я думал помпа купил поставили и началось греть хотел таким способом как у тебя проверить её но не получается думаю уже может быть сама помпа брак

Сожалею. Знаю лично какой это геморрой менять эту дрянь.

Without driving the car, does it get warm/overheating warnings to come on?

@@EliteBimmers yes after a while the water starts to overflow while trying to do the bleed. New water pump and thermostat

Not sure what is going on :( Sorry, you have problems with this. This week I worked on a car where this process lasted only 5 minutes and the car would go to sleep. New battery and stuff. We ran it several times and it doesn't overheat. BMW diagnostic software showed everything is fine. On these cars, it can be a nightmare to perform such a simple thing :(

@@EliteBimmers just found out it was the auxiliary water pump not the one on the motor smh after waisting money. Thanks for the response

Yes, instruction was only for ELECTRIC water pump. For those E60 owners with mechanical water pump including myself, we are out of luck. No instruction at all online :(

With mechanical: park up to hill,( higher-better ) with nose ( engine ) up! Open tank,start the car,put heating to max/fan to min,and wait till coolant go down,add a bit of coolant if need,press gas pedal from time to time… in aprox 1hr the job is done.

@@letmetrade6804 I love you

Cold car sir.

No, it doesn’t

Hello! Thank you for your comment! I talked to several BMW owners from Northern Europe and seems that 520D is a solid choice for this part of the world. Sweden gets a LOT more snow than the place where I live now. My car is all-wheel drive, xDive, and it handles great on snowy and wet roads. If you can, get an xDrivr car too, unless it’s not possible, good winter tires should be sufficient. I owned a couple of rear-wheel-drive BMWs and drove in the snow without problems.

@@EliteBimmers thanks 🙏🙏🙏👌👌👌

@@EliteBimmers people said the timing chain can go of in the 520D or 520i but i didn't feel anything in my 520d that I buy it.

I would say it’s similar to all E60/E90 models.

Is it ?

I’m not sure exactly which pump it’s using.

It's venting inside the reservoir tank. There's a small hose inside, if you open the cap during venting, the flow or bubbling can be seen. If the car has extra coolant, it would just drain outside. Most likely you would need to add more, and will not see overflow.

is the same for e63 645ci , too ?

Remember its venting AIR from the coolant, so may not see anything but may hear bubbles

😀

I’m not sure.

Можно на русском тоже)

Сложно сказать, этот метод не контролирует скорость прокачки. Может быть не хватает напряжения на помпу? Или сама помпа накрывается. На этих моделях электрическая помпа наверное самое слабое место. Я прокачивал этим способом много раз и понял что здесь главное время (около 12 минут), чем дольше тем лучше.

Bad water pump

That’s a very good question. I’m not sure, but I would guess you don’t have to because iDrive would say that when you get a warning about adding a coolant.

The car that’s on the video has an electric coolant pump. But I learned that mechanical pumps (belt-driven ones) use the same venting method because those cars have electrical auxiliary pumps. Learned this a month ago.

@@EliteBimmers I was thinking that 😂 thanks for verifying

Maybe the battery is not charged/too low?

Without bleeding the car can have air in the system, and with the air trapped inside it can overheat.

@@EliteBimmers thanks bro

This one is N54.

@@EliteBimmers I went today with my bmw e60 520d N47 engine to change coolant and they didnt vent the system ,they sad it will vent by herself and they let her runming for about 10 minutes ,it seems the engine is working at normal temp by now 🤔,that’s why i was asking about engine code ,probably n47 is different when it comes about venting 👌

Thank you for your comment! Yeah, looks like all of these engines have different guides for this :)

@@EliteBimmers Thanks too ,I will try the buttons combinations with the gas pedal to see if anything will happen 👌

Does your car overheat?

EliteBimmers yes. Mine overheats

Giovanni Ramirez It could be few things. I would start by checking if your coolant pump is working and if your battery is strong enough to handle 12 minutes or so of the venting process. Good luck
