I own a 2006 GC SXT with 70K miles. I recently started notice fluid loss(oil and coolant). After filling these fluids with recommended brands, I am now beginning to notice coolant spots on driveway. Coolant drops are present under center of engine. My guess is that the rear headgasket is leaking. There is no coolant in the oil and the van runs fine. Is my guess fair or is there some other problem?

 

Welcome to DF
Pressure ck the cooling system and find the leak. It may or may not be a head gasket. Maybe a water pump.

 

ya pressure test it, could be something as stupid as the hoses to the heater core leaking at a clamp.
wont know till its tested
