Got a new to me skid steer, has 5000 hrs on it, and runs like a top absolutely love it. Having an issue though that is troublesome, I'm finding that over about 30mins of running the water temp has creep all the way up to where it says its overheating on the gauge cluster. There is an indicator light that is for the water temp but it doesn't turn on when I experience this issue. I find that the temperature just a steadily creep's up until its in the red no matter how hard I run the machine. Im assuming this is a stuck thermostat, any other suggestions?
