Jeron,
I purchased the book and did the full water pump / tstat / hoses / belts replacement this weekend. Although everything went well, I am now realizing what you mentioned earlier which is that the bleeding is the trickiest part. The book goes over it very lightly and the forums are full of "Here is what I do" and "Here is what Bob does", none of which really explains how this strange e36 bleeding system works.
After having filled the system with the bleed screw open and engine cold, I realized that if I then ran the car around town for a bit, coolant would leak past the reservoir cap. As if pressure from a hot engine made the coolant bubble out. After the engine cooled down, I opened the bleed screw and heard a good deal of air coming out. But curiously, as the air came out, the coolant level in the reservoir went up dramatically, almost to the top of the reservoir. This is very strange because I would think that if I let the air out of the system that would get replaced by coolant and, if anything, the coolant level should drop and not increase ... What is going on there?
I have noticed that you recommend doing the bleeding with the engine hot. I will have to try that tonight.
Thank you for any help,
Bo
