I have a 96 honda passport with a 3.2L V6. The temperature gauge maxes out at the hottest point just after about a minute of running. This is after sitting over night. I have replaced the waterpump, timing belt, thermostat, flushed the radiator, and replaced the coolant. Yesterday I took the thermostat out and ran the engine and still the gauge maxes out after about a minute or two. The darn temperature sensor is between the engine and the firewall and very had to get to. Does anyone know what the problem could be? Air pockets, bad sensor, bad ground ???

I would suspect a bad sensor, cause it should at least take a minute or two for a cold engine to warm up. How about inserting a thermometer into the radiator through the cap opening and measure the temperature? I guess that the thermostat might remain close with no water circulating in the radiator within the first few minutes.

Thanks for the response. I ran the engine for twenty minutes without the thermostat, then opened the cap and the coolant was warm to the touch. So I know the coolant is circulating.
