Once the engine warms up and the thermostat opens shouldn't the level in the expansion tank drop??
Using the newspaper test does the fan slow down gradually means the clutch is OK??
I've got a 91 318is and just flushed the system? As I run it wth cap off I never see the coolant level drop. I don't see any airbubbles so I think their all out of the system. Temp goes to 3/4 mark now.......
