Lately my car has been running hot and I can't seem to figure out why. Does anyone know the standard procedure for testing the coolant system? I ran a search and found conflicting procedures. Also talked to a rotary specialist shop in my area, and their procedure seems to differ from what I have read on the forum and whats stated in my manual. Right now I have the pressure tester hooked up to the AST with about 18 psi and it's been holding for the past hour steady.

 

well that seems ok then, youve probably got an airlock.
