Why is my antifreeze being used up so quickly and i cant find a leak

Asked by Jan 10, 2014 at 12:50 PM about the 1999 Pontiac Grand Am 2 Dr SE Coupe

Question type: Maintenance & Repair

1 Answer


Have the cooling system pressure checked, you might have a loose hose connection that only blows off antifreeze when your car is moving. Antifreeze can also find its way into the crankcase via a failed water pump seal, head gasket, or several less common problems. In that case your oil will be foamy or light brown. Do the pressure test first.
