Hello all,
I also need to get the leaky waterpump of my 2020 Bmw 320i 1.6lt with B48 gasoline engine.
Only concern is that I can not find any service that use vacuum pump to do the coolant fill process. They all say that they do it as drain , replace water pump and refill from both of expansion tanks while the air release screw is open and run the car.
The only thing I will be able to get done will be massaging all hoses while filling the coolant just before starting the engine.
However I do not know whether vacum pump method is essential or optional for my car and whether there is a risk to create air pockets and blow headgasket if it wont be possible to fill enough coolant at this specific b48 bmw engine?
Last year I have already changed coolant myself of both high temp and low temp circuits without using a vacuum pump. Instead I massaged hoses alot and it was successful but after running the car I had to add quite amount of coolant. However I now worry because removing waterpump will probably cause further loss of water. Or will it be the same if water pump is already connected to the lower radiator hose? I am not sure though.
Is there anyone who has done or get done waterpump 11518638026 replacement at this engine without that vacuum pump without blowing headgasket?
Look forward to read your responses.
Many thanks in advance.
