Post four for this newbie; I promise no more for today after this.
Also, thank you all for the feedback on my other posts. To recap, I am
switching from polishing up 1980s Volvos to mid '90s BMWs and am
trying to learn all I can before I make the purchase of a '91-95 5er
I've heard BMW has something called a 'Pressurized Cooling System.' I
do not understand this term. I am familiar with cooling systems that
have a pressure sensitive radiator cap, like the old days, to let off
steam. My Volvos do not have radiator cap, instead the reservoir cap
is the same. I've tried searching this forum and Googling, but cannot
find an overview explaining the details of how the system works.
Why this post? I'm reading a bimmer forum (http://www.bimmer.info /
forum/showthread.php?t435&highlight=overheating) and this guy has a
heating problem in which his headgasket is about to be shot and white
smoke is about to come out of the pipes.
It has not YET. What if I am looking at a car that someone has, with a
similar problem, and they try and dump it before the obvious signs
appear. How do I test for this? Is there a good way to know if a car
is about to suffer some head gasket damage or failure?
Please advise. Many thanks!
