What kind of antifreez for a 03 grand am gt?

Answer 1

it is called dex cool it is made just for newer gm vehicles. If you don't know what coolant you need you should have a shop change it for you. that is not an insult. if not done right you could get air in the lines and blow your moter a head gasket or a few others. the engine and heater core sit higher than the radiator and you will get a air bubble even if you bleed it out with the bleeder screw. you would need to park on a hill or jack the front of the car to do it right. my friend learned the hard way. don't believe me ask any mechanic that knows what he is doing.
