Another mechanical thing that can cause overheating is a sticking thermostat. Is it original (i.e. 24 years old)?

If you have an IR gun you can confirm actual overheating VS sensor issue.

You reset the fault on the grey box that is above the fan.

Chris,

Which power unit do you have? Isuzu or Kubota as location will be different.

Chris,

On ours the probe is rite beside the thermostat housing on the top of the head.  Yours may be different as I have seen them on the head between the cylinders on the back side of the engine also.

2 years ago I had the same issue and found my radiator in the remote location , it sits in front of the left front wheel in the side door where you pull the latch to open your generator door in the front! The radiator was completely plugged with dirt and the material from the deteriorating insulation in the generator compartment. Removed it and cleaned it by running water through the tubes and fins on the outside, had it pressure tested for leaks and replaced it. Been fine eversince.
