my montero has recently develpoed a temperature spike where the gauge will move to hot right away but will slowly creep back down, the first time it did it I was at a stop light, so as I pulled over when I started to drive it creeped down I thought it might be the fan clutch, it continued to do it as I drove, I knew the thermostat was going out so I changed it continued to do it.
its not as sporadic as it was but its still does it. I am not losing coolant Ive replaced the temp, sensor and the gauge sensor.
I hear no noise from the waterpump. it seems to be operating correctly, Ive flushed the system, and the fan clutch seems to be operating correctly. I tested it with a rolled up news paper when it was at operating temperatureand it continued to run.
am I missing something?
oh when it overheated one time I immediatley shut off the engine, and started it back up within 30 seconds,
the temperature went to operating temperature within 30 second this leads me to beleive its really not overheating????????

i think yuve missed the Pajero/Motero/Shogun section
