THIS SOUNDS CRAZY BUT, ON SOME OF THE OLD SCHOOL CARS, THEY HAVE A CLUCH FAN.. AND IF ITS BAD, THE CAR WILL OVERHEAT WHEN DRIVING AND COOL DOWN AT IDLE.. I DONT THINK THE CADY HAS A CLUTCH FAN, BUT I BET ITS IN THE FAN.. GOOD LUCK KEITH..

Engine over heats Replaced water pump and thermostat and 2 bottom water hoses


Check your oil for any traces of water. The oil may be foamy or milky in color. The culprit may be a blown head gasket that over heats the coolant.

What is the correct temp on a 1998 Cadillac DE ville my cadillac is not should me the correct temp in my gate and is overheating.


Before you do anything, have the engine teperature checked out using an accurate thermometer or thermocouple. Gauges are not always reliable and at best are only ever an approximate indicator. If the engine is actually overheating, check your thermostat first. Next check if the top radiator hose is hot and the bottom hose cold. If this is the case, your radiator may require flushing. The bottom hose should be cooler that the top, but not cold.

Why does my cadillac 1998 deville keep overheating?


Overheating can be numerous things: Fans not working, water pump, thermostat, overflow cap, and the list keeps going. When the engine is running and heats ups, feel the heat of the top hose, if the hose isn't hot, the thermostat is most likely stuck open and needs replaced. If it is hot we know you have circulation. The cap on the expansion tank may be defective, if it can't hold the pressure of the water, it will release at the overflow cap if the cap is bad. Also check the coolant level.

FIRST OF ALL ADD COOLANT TO RADIATOR ITS LOW.THATS WHY CAR IS OVERHEATING CHECK FOR LEAKING HOSES OR RADIATOR. ALSO YOU NEED TO ADD OIL TO BRING OIL LEVEL TO CORRECT LEVEL.HAVE THE ALTERNATOR REPLACE.BECAUSE ITS NOT CHARGING CAR BATTERY.CAUSING THE CAR NOT TO START.
