I guess you can use any coolant that is compatible with the dex coolant. Many auto part stores carry their own brand and Prestone has been around a long time. I'm sure that these anti-freeze formulas are compatible with GM, Ford, Chrysler and any foreign car coolant. You should drain your old anti-freeze anyway and add new (50/50) antifreeze and water mix. You can check the % mixture for the climate where you live.
