SOUND LIKE COOLANT FANS HAS A FAULTY THERMO SWITCH LOCATED AT THE BOTTOM OF THE RADIATOR ON LEFT HAND SIDE.CHECK THE FUSES 8 IN THE ENGINE COMPARTMENT AND CHECK FUSE 16 IN THE PASSENGER COMPARTMENT FUSE BOX.WHEN ENGINE OVERHEATING IF BOTH COOLING FANS WORKING.OVERHEATING PROBLEM COULD BE BLOWN HEAD GASKET.CHECK ENGINE OIL LOOKS LIKE MILK HEAD GASKET LEAKING.SEE WHEN YOU DRIVING LOW AND HIGH SPEEDS THE COOLING FANS SUPPOSE TO BE RUNNING.IF THEY NOT RUNNING THAT IS YOUR OVER HEATING PROBLEM.
Thanks hotchevy1965. I'll check those things out. It is my lady's car so the first thing I checked was the oil to see if it was low or milky, not the case. I'll look into your advice and repost when I figure it out.
New thermo switch installed, same issues. Cooling fans work fine. There is no fuse box in the engine compartment, Fuse 8 is for a Telephone System (not installed) and Fuse 16 is for the AC clutch. Sorry HotChevy, your advice did not help resolve this issue.
I AM LOOKING AT IGNITION TIMING OFF AND FAULTY RADIATOR CAP.DO YOUR CAR OVER HEATING WHILE MOVING OR SETTING STILL..IF OVERHEATING MOVING FANS RUNNING YOUR ENGINE BLOCK AND RADIATOR NEED FLUSHING AT A RADIATOR SHOP.THEY NEED PRESSURIZE THE COOLANT SYSTEM AND LOOK FOR CRACK HEAD OR LEAKING HEAD GASKETS.
