My daughter called me today and said she took the car to a mechanic and he thinks it's the head gasket.....HUH??? Motor
oil looks clean, no gray/white smoke from exhaust, no external leak and reservour level holding okay.
One thing I didn't check was if the radiator fins were clogged preventing an air flow. I'll check that tonight.
Thanks guys.
