HI, new to me Rhino that started overheating last time I took it out. Was running for about 30min before the light came one, It wasn't steaming or boiling over or running rough at all, but the light was on. I drove through a few semi deep water pools and the light went out. Radiator was clean, coolant is clean and full. Anything known issues I should address? Thermostat, coolant change, water pump? The light did not come back on on the way back so the water dunk did cool it off enough for the 20min ride back home so the issue doesn't seem to be anything major.
