I have a 99 caddillac deville. The temp gauge on car keeps going up and up over 250 degrees. Its making the car spill radiator fluid constantly. The fan works. Could it be the thermomitor that is stu
Thermostat stuck as you say,or water pump is bad.
How do u test to see if the water pump is bad
Could a bad upper radiator hose cause the car to overheat
Yes if hose,s is drawing in or colaspsing,when hot,and you can test water pump by cranking car let it heat up,have radiator before you crank car,when thermostat opens, you should see the water circulating.
