Engine Cooling problem
2001 Mitsubishi Montero 6 cyl All Wheel Drive Automatic 122000 miles
2001 montero starting over heating. I replaced the thermostat but got same result. I removed the thermostat and it quit running hot for a couple months. Now when I crank up and run it will register on the temp guage half way to just above half hot. The guage will sometimes bounce up to 3/4's and back to half. Whenever I stop with the engine running the temp doesn't rise or fall. Whenever I shut the engine off and turn the engine back on in 1 to 20 minutes the guage is pegged out hot. After it runs for approx 3 to 5 minutes the temp guage comes back down to half way.
I put another thermostat in and within 5 minutes of running it pegged out hot. I could here the water boiling and tell by the tightness in the hoses that it was very hot. I unscrewed the vent bolts above the therm and on the top hose side it released lots of pressure but no water. I was able to remove the radiator cap and it boiled over. When I removed the therm it was still open so it was working correctly.
have the same problem?
