I'm having the same problem and it's driving me nuts! Now the car idles at 500rpm then dies. Whenever (cold or warmed up) I turn the key the temp gauge goes straight up to the top. I replaced the thermostat, water pump, temp cooling sensor, cooling temp gauge, upper & lower radiator hoses, & flushed the radiator. And this $#!+ still reads that it's overheating. What gives? I just dropped this motor in and already replaced the headgasket. No coolant is leaking into the block. Please someone help!

Try unplugging the coolant temp sensor and run the car. I dont know what else it could be. If its reading hot maybe you have air in the system. Try to also top it off. Run on hot at full blast and then top it off after that.

The sensor is located beside the upper water neck under the intake manifold. Mine was color coated (green for coolant). The sensor should cost around 22 w/tax. At least that's what I paid for it. If you do decide to replace it then you'll need a 19mm deep socket. Be sure to disconnect the negative batt terminal. I had to rip the sensor off the nut in order to loosen it properly. The 19mm does fit over the sensor on to the nut it's just that you can't get a sufficient grip and the socket just slips of increasing the chances of stripping it.

so when the Gauge reads High is there any coolant bubling in the coolant tank? if not then it might be your coolant sensor as mentioned above.. you might as well replace it.. its pretty cheap. i remember getting one for 30 bucks or something from napa

I forgot to mention. When my sensor went out the car went into a kind of safe mode. I couldn't put into gear. So that is one way of telling it's the sensor. It mentions something about the safe mode in the service manual.
