Remove the cap from the coolant bottle and fill it all the way to the top. Then start the engine. Does the coolant shoot from the bottle?

Car running hot


Check fan relay and wire connections; if they are ok, and the fan work if you jump directly, could be the temperature sending unit, engine temperature sensor out of range or thermostat stuck. Stop the car, could overheating and damage other components and engine itself.

REPLACED RADIATOR NOW IT RUNS HOT....IS THERE A BLEEDER VALVE


Did you replace the thermostat at the same time?

Is the fan running? Put the a/c or defroster on, the fan should run.

Check for bad thermostat or installed incorrectly as well as the fan running (might have missed something with the wiring).

Hope this helps.

My Cadillac Deville, 2002 northstar is running hot........or the temp gage goes up and I have to stop driving..I have a new thermostat,relay switches for the fans,temp control sensor and a new coolant...


Check the fan to see if it is going on. On my 1997 Cadillac Deville Limousine I had to have the 2 fans, and 3 relays replaced, as well as the wiring contacts for the relays at an auto electric shop for about $700 last fall, but it has been running cool since then.

Cannot find overheating problem 1997 cadillac deville. we have installed new radiator, fans work fine, new water pump, new thermostat, catalyic converter, new hoses, and we cannot find any leaks. please...


These engines are know for leaking head gaskets. A good quick test for this is fill the coolant tank to the top with the cap off. Start the engine. If the the coolant blows out of the tank, you have a head gasket leak.

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.

It sounds like they didn't get the cooling system filled completely, there's an air bubble. I had a problem with a 2000 Oldsmobile overheating, it turned out to be the aftermarket thermostat. I bought a stat from GM the problem went away.
