I recently bought a 2019 057 with 300hrs on it. Very good condition. We have used it a number of times and it has worked flawlessly. Today it started to get hot doing light work. Let it idle and it cools down but not all the way.
Rad is clean, belt is good. Fan is pulling lots of air through rad. Plenty of good green antifreeze. I am thinking the thermostat is stuck closed. Expansion tank was pretty full, rad is very full and didnt seem to have much pressure when I removed the cap (I had a big towel over it and slowly opened it when hot and nothing. No steam or gurgling. Motor did seem pretty warm, so I think the gauge is right.
I am thinking either cap or thermostat. First kubota motor I have ever had an issue with. It looks like I can get to the thermostat through an access panel in the cab. Anyone ever have an issue like this? Guess I need to get a service manual too! Thanks.
