I have a leak in hose #1 cooling system pipe to water valve. Is it necessary to drain the system to replace hose #642221388930? Thanks
The p/n does not work, BMW p/n is 11 digit, that is 12 digit. I assume you are talking about a hose in this area http://www.realoem.com/bmw/enUS/show...diagId=64_0146 you will loose some fluid when you replace that hose, just add some coolant after the repair.

My typing is not so good! Yes that is it. But when the fog cleared the # was 64211388930 on the hose itself was from engine cooling diagram #16. http://www.realoem.com/bmw/enUS/show...diagId=11_0785. not 64211384763 on the valve diagram. I don't know what happened to the font? lol
Good to hear I won't lose much fluid. I have Prestone fluid which is okay for aluminum radiators, which I am assuming is fine with a 50/50 mix of distilled water?

no need to buy one, be inventive, a grip plier with some flat metal strip on each side so that it is not too sharp. Or something like this https://www.amazon.com/TEKTON-39180-.../dp/B000NY4UDQ
50:50 is fine
