I had a similar (read: exact) problem. It was caused by the cooling fans not opearting. I spent $800 having a dealer sort it out. The problem was a broken ground wire between the relay box and the fans. You can troubleshoot them by jumping 12 vdc to the teminals on the fan housings. You'll have to disconnect the harness wires to do this. In the end, my cooling problem has been repaired and I do not know where they installed the wire. Temporarily, use your heater to cool the engine. Run it at max temp, max fan to cool things down. It's not the most comforfortable solution, but for temporary use it will keep your head from heat warping. Eric

I was having the same problem with my car. When you take the thermostat out it will automatically read cool. But I later found out that I had a leak in my radiator and had to replace it. Turned out that my heads are warped and was leaking oil into my water and into the radiator itself. Once i replaced the radiator its been fine.

Why does the thermostat keeps turning on and off?
Because that is its job! A thermostat is a device that measures the temperature of a given space or volume, and turns heating / cooling devices on and off accordingly. The thermostat in your house is designed to turn the heating off when the house is warm and turn it on when the house is cold. The thermostat in your car turns the radiator fan on when the oil / water temperature increases to a level that could be damaging to the engine (if you are stuck in traffic for example)
