My car is overheating, replace thermostat, head gasket, and still overheating what can it be?

Blown head gasket/warped head due to overheating.

Blocked cooling system most likely a stuck thermostat. The coolant is not circulation therefore not getting to heater core. Replace thermostat and it should be fixed

Head gasket blows easily and will continue overheating.

If you overheated your Contour, you have also probably blew the head gasket AND warped the head but hopefully Not.

The Thermostat is removed by removing the 3 bolts on the housing. Install the Pill DOWN.

Recommend that you replace it with a "FAILSAFE" thermostat and I do hope you did not do any damage to the engine

Sounds like your coolant is not circulating. Replace the thermostat.

CHECK COOLANT LEVEL FIRST BUT IT SOUND LIKE FAULTY THERMOSTAT OR LEAKING HEAD WILL ALSO CAUSE OVERHEATING WHILE DRIVING.I WOULD REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP FIRST.THAT WAY YOU KNOW IF HEAD GASKET LEAKING.CHECK ENGINE OIL IF IT LOOKS LIKE MILK SHAKE HEAD GASKET BLOWN.

If you are going to the expense of replacing the head gasket, it would be false economy not to also replace the thermostat at the same time.
Particularly if you are attempting to solve a overheating problem.

I would go with slowcalafl. It is either air, or a cracked head bad head gasket. Remove the radiator cap when cool. Start up the car and watch for bubble emerging from the coolant. If it continues to bubble, you have a bad head or head gasket. If not, look for improper timing as another possibility.

Its not impossible for there to be a bad head gasket or leaking. But I agree with you the over heating will be there during driving as well. I would change the fan clutch and replace the thermostat, if the thermostat that was replaced wasn't an oem/delaer thermostat, I would change it. From prior experience with these type of vehicle the most likely cause of overheating thermostat and fan clutch. Aftermarket thermostat just aren't good for this vehicle I have proved it a few times for myself. Take my advise and change the thermostat with an oem one and the fan clutch with an oem. Good Luck. Get in contact with me if you need more help.

Multiple causes for overheating. Start with thermostat.

I had an overheating problem in my Subaru that ended up being a head gasket (I replaced thermostat and radiator, but these did not help). It turned out that the head gasekt leak was allowing air into water passages that prevented water circulation in the engine.
