1999 Pontiac Grand Am GT 3.4L Heater Core
Hello Put a new intake gasket in about two weeks ago. The owner says no heat from the heater at idle. I have bled the system a number of times. When you increase the RPM to 1500 you have lots of heat. But when you let it sit and idle you will lose all the heat...
