DexCool. However, if you completely flush the entire coolant system clean, you can use whatever you want. GM recommends, and will only warranty the engine, DexCool as the coolant.

DexCool is only a few bucks more per gallon, and your car only hold about 2 gallons total. I just flushed my car and used Havoline brand DexCool. Just make sure whatever brand you buy, it say DexCool on it. And make sure that you either premix it to be 50/50 coolant/water, or buy the premixed stuff. Like I said, you'll need about 2 gallons of mixed 50/50 if you flushed the engine out.

MY 2004 PONTIAC GRAND PRIX GT IS OVERHEATING I FLUSHED IT NEW COOLENT AND NEW THERMASTAT AND IS STILL OVERHEATING WHAT SHOULD I DO?


Run water over the radiator while it is still running and see if the temprature goes down. Likely your radiator is stuffed up. A rod out done by a radiator shop will save a lot of money.
