John Deere 5425 Overheating Under Load

[mark.cash1964]

I have a John Deere 5425 with cab. I can run the tractor all day under load without the AC on and no overheating issues at all. I can turn that AC on and I can start watching that temp gauge slowly go up until I have to turn it off. The temp will return to normal. I have made sure that the radiator and AC condenser are cleared every time I go to the field. What am I missing is the fan system inadequate? Is there aftermarket improvements I can do to the cooling system. It doesn't stop me getting finished what I am doing but at that point an open bay would be cooler than me under glass. TIA

Did you get this issue fixed? My tractor is doing the same thing!

Not really, I purchased a better air wand to clean out the condenser and radiator. But as you know there is really limited access to the back of that radiator. I actually saw an aftermarket radiator fan that you could reduce directions and blow out the radiator but it was pricey.
