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 E34.
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
Please advise. Many thanks!
