To change the thermostat on a Case 70XT skid steer, first, ensure the engine is cool and disconnect the battery for safety. Locate the thermostat housing, typically found where the upper radiator hose connects to the engine. Remove the housing by unscrewing the bolts, take out the old thermostat, and replace it with a new one, ensuring the correct positioning. Finally, reassemble the housing, reconnect the battery, and fill the cooling system with the appropriate coolant.
