Re: 2004 grand am gt air in cooling system

Only one way it can get air, it has a leak somewhere......

3.4L? Usual places are lower intake gaskets(look in engine depressions on top of block under the throttle body, for coolant collecting....w/p weep hole.....heater core.....radiator.....hoses(radiator/heater core)......bad radiator cap or reservoir cap......head/head gasket......

If I were checking for a head gasket leak, I would be doing a leak down test, rather than a compression test.....
