Removing the thermostat can actually make an overheating problem worse. I would check the radiator fan.
Take your thermostat out and put everything back together, run your car without a thermostat... If your car no longer overheats, replace your thermostat.
water pump
check your fluids it is probably low on antifreeze and if it still does it change your thermostat that should fix the problem
check your radiator. is it clean or does it need to be replaced? a simple cleaning cured my problem.
check the weep hole on the bottum of the power steering pump.. if it is leaking the pump could be the problem..
Change the thermostat. lol. Simple but the water pump wont work if the thermostat is stuck closed. Good luck. Kyle
My guess is the head gasket, have same problem. Nightmare
It could be the thermostat. Open up the radiator cap when it is hot and see if the water is flowing in the radiator. If it is not then it may be a thermostat.
did you try replaceing the thermostat or radiator or even check the hoses
check the heater core stopped up radiator
Most likely it is a bad thermostat. The switch on the radiator fan could also have failed.
check you water (coolant) level, make sure thermostat is working, radiator leaks, sensor problem
