Question about 2005 Pontiac Grand Prix
System is air locked and runnig hot
You can take the radiator cap off when cold and let run till thermostat opens and air bubles through hole. This will cause you to loose some antifreeze but you refill it while car is running. You may have a tube on tope the intake manifold usually on the left/drivers side that can be loosened once car is warmed up. If you go the cap route and the antifreese continues to blow out after filling, you have a blown head gasket.
