I hear gurgling in the system after the engine is shut off (not including the sound of coolant dumping itself in the expansion tank)...is that a symptom of air in the system? If so, how does one go about removing air in an M104?
Also, a couple of times when things got hot enough to purge coolant out of the expansion tank, the upper hoses were collapsed when the engine cooled down. I had to relieve pressure by opening the cap. This doesn't look normal either...
