I have a 97 caddillac deville and it is overheating everytime i run it over 15 miles. I have changed the thermostat, the water pump, the water pump base gauskets and the radiator cup, and it is still overheating. what could be the problem? can i know what the average/normal temperature on my car is? is there any website/youtube video that could help me? thanks! :D
 
Make sure the thermostat was placed on correctly (spring pointed down). The replacement thermostat should be a minumum of 195 degree. Also make sure you burp the system (trapped air in the system). To burp the system, just raise the front end of the veh, The radiator cap should be the highest point of the cooling system. Remove the radiator cap and run the engine at idle. give it about 5-10 minutesand hopefully there were no air pockets in the system. Also check the catalytic converter. A plugged converter will raise the temperature as the engine heats up. Or just try another thermostat. Good Luck
