Are you implying by posting that long list of part numbers that if Uncle Levi replaces all the parts you listed that his tractors overheating problem will be FIXED??

I am not a mechanic, but have fixed my fair share of cars.
I once looked at a friends BMW, who changed the radiator, thermostat, water pump, flushed the waterways and it still overheated.

After a wee bit of investigation, I found the problem to be a faulty pressure relief cap. A pressure relief cap that does not discharge at the correct pressure will lead to overheating problems.

I have not seen you changing this part, but is certainly worth testing before digging too deep (if not too late!)

not a JD guru by any means, BUT - I once had a car that would overheat. Tried everything & finally, when I pulled the head, I found a piece of slag in the coolant passageway. It stayed put at low idle but would get pushed by the coolant & almost completely block the flow. I like the idea of a camera to inspect inside the block / cyl liner areas. Prayers for you, wife & family... Good luck with tractor.
