    Where would the fan clutch sensor be located on a 2007 pete 379 c15 engine 18 speed be located, fan clutch kicked in hasn't turned off? Also what is the normal temp oil/coolant when running truck with a load being carried not sitting idle?

    It's controlled by the ECM. You could have an A/C issue, the A/C overrides the fan. Other causes could be a problem in the override switch or wiring, fan hub itself leaking internally. Air releases your fan, so a lack of air, bad fan solenoid, or fan solenoid wiring could also cause it to stay on.

    That's all assuming that the engine is running cool enough not to need the fan on.
