Make sure that the purge line is clean and the system will purge itself. If the purge line is clear and you still hear air the heater core and the engine is overheating, the "air" is being introduced to the system. Most likely by a bad HG. Might be time for a block test.
Agreed but I never said the car is overheating it runs hotter than normal like the one notch past half and as soon as I bring the rpms up higher the temp will return right back to its half way mark
