my guess is the thermostat if you just replaced the thermostat then it might be an air pocket in the cooling system solved by taking the cap off the overflow tank squeezing the radiator hose going to the thermostat housing until the water pressure opens the hose in your hand this forces your thermostat open. if you decide to replace the thermostat yourself do the same as above to make sure all air is out of your cooling system.

Low of coolant, defective water pump, clogged radiator interior or exterior, cooling fans not working, thermostat installed up side down, or you may have bought a bad, new, thermostat. It happens. Also running 100% water will cause it to overheat. Run a 50/50 mix.

You can remove the thermostat, but you son't want to. That will cause the computer to think that the car has never heated up properly and make it run as if it needs to heat up. This will affect fuel economy, power, and longetivity of the engine. You will be better off fixing your cooling system wherever the problem is. DO NOT REMOVE THERMOSTAT!!!!!!!!!!! the Computer will run in Limp Home Mode forever until its replaced, really bad economy,Worse Performace,will run the cooling fan constantly.

I don't have a thermostat in my car will this cause the head gasket to blow?

No, The thermostat just causes the cooling water to get to operating temperature faster. It restricts coolant flow to the radiator until it opens. However, if you replaced the coolant with plain water when this was removed, that could have caused the problem. Plain tap water in an engine, especially one with an aluminum block, may cause a chemical reaction and cause internal damage. Antifreeze helps to prevent this and provides lubrication to the water pump.
