BMW 2004 330i automatic. About a week ago I put "stop leak" in my radiator because I had a hairline fracture in my expansion tank. I just replaced my expansion tank and transmission thermosat and took it for a test drive and it ran hot, but the coolant wasn't hot at all. Any clue what the problem is?
have the same problem?
