Why does it cost so much to repair the head gasket on my vehicle? I just had a brand new thermostat as well as a brand new water pump put on the car initially the problem was the ECT engine coolant temperature sensor could this be the reason why the car over heats i don't belive its the head gasket
Why is the repair cost so much? on 1996 Cadillac DeVille

It's a 4.6 I assume? If you do not flush the cooling system at least once a year you invite this problem. 4.6 V-8's have a inherrant problem with blown head gaskets. I have used BLUE DEVIL coolant sealant on 3 caddy's with a 4.6 & have had great succes in stopping the overheat condition. Contact me at email@example.com.
