I have a 1998 cadillac Seville delagance I've changed
waterpump, radiator, hoses, cap, and there's no water in
oil or oil in the radiator and still over heats
thermostat? or change to a different temp thermostat?
If you didn't over heat it and cook the head gaskets, Inspect for a bad radiator, loose fins, corroded areas etc. Check the coolant for combustion by products Hc, Co, etc... use a SIMPLE chemical test kit to confirm there is no damage from over heating. Regards
Is the a/c condenser free of bugs, dirt and other debris? Was the thermostat replaced? Is it losing coolant?
