I have a Bobcat S250 skid loader that is throwing a warning code of 8-21 after about a half hour after its been running. The code says Coolant temp out of range high. I dont know how big of a deal it is too keep running it after it comes on usually try to get it parked as quick as possible after it comes on. Changed the air filter and cleaned the radiator (wasnt very dirty) Cant figure out exactly what to do to fix the problem tho. The engine temp has stayed in the same range as when I first got it so makes me think that it could just be a sensor going bad. Anyone have any advice on what to try next?
