Is there still a possibility that I have air trapped in the heads?
The car runs really cool (180) on the highway, but sitting at an idle it acts like there maybe air around the temp sensor because the fans cycle off and on rapidly, as well as the mechanical gage temps go up rapidly. If I keep the RPMS at 1500 or so, then the temps stay down.
Is there something that I should do to be sure that there is no air trapped in the engine somewhere?
Also, are most people still running the warmed water thru the intake air inlet ( can't think of the proper name), or are they bypassing it too?
Thanks, Tom
