Anyone have a diy to change the coolant in an e39 (2002) 530i or a link to one? I dont think its been changed yet since my father has owned the car... thanks!
It's supposed to be done at least every two or three years. There have been many DIY writeups on many of the BMW forums. Here are a few. Just use their Search function. http://bimmer.roadfly.org/bmw/forums http://www.bimmerfest.com/ http://www.bimmerboard.com/ http://forums.bimmerforums.com/ It's a relatively simple process but it must be done correctly or air gets trapped in the system and overheating problems occur.
