Check the engine oil. If you pull the dipstick and it has white goop on it the head gasket is blown or the intake manifold is leaking. The heater core may be leaking as well. Does the windshield fog over on the inside or do you smell a sweet smell inside of the vehicle? If so the heater core is leaking. Hope that helps! Jim
