Thread: '04 Grand prix GTP problem galore

Where are you in NH? I'm not the world's biggest expert on these things, but I know some stuff and maybe we could meet up somewhere

My mechanic said theres several factors, either a leaking intake manifold, junk thermostat an waterpump, or radiator. we just replaced a valve manifold due to leaking oil onto the headers. Would also like to add when the temp guage boosts up all the way to spiked, itll occasionally drop down to the bottom of the red zone, and then jump to the top again
