Default Engine running hot?

My 3.0 is running hot, but only when sitting still. I have checked the fan and the thermostat and neither of those were the problem?

Default Re: Engine running hot?

The only thing different about moving and not moving is air flow through the radiator and water pump RPM.

1) The fan clutch is dead. It will never stop so just because the fan is turning doesn't mean its working right.

2) The water pump impeller blades are starting to go and idle RPM isn't moving enough water.
