leaking head gasket
I flushed the coolant system and replaced the thermostat and radiator, idled it and it was fine.... Until I drove it and got up to 60 and it started to spike in temp. Tried the "Cadillac Pills" and nothing. Seems that it's a leaking head gasket that puts combustion gases into the coolant system creating steam and air pockets and over heats it. So my last ditch effort will be to flush the system and add the Blue Devil gasket sealant to try and repair it otherwise it's going to be tearing the head(s) off and replacing the head gasket and head bolts and checking the head surface.
