I have a 1998 chevy lumina we put a new radiator and thermostat in it and we have to keep bleeding it to have heat why do we have to keep bleefing it?
try changing your overflow tank cap and make sure your not losing any antifreeze and if you are check your oil level those cars are bad for intake gaskets and they leak antifreeze straight into your bottom end... but also silly i know but just to be sure... you put the thermostat in the right way right?
