How do you replace Kubota thermostat?

To replace a Kubota thermostat, first, ensure the engine is cool and disconnect the battery. Remove the radiator cap and drain the coolant. Then, locate the thermostat housing, typically near the engine block, and remove the housing bolts. Take out the old thermostat, clean the surface, install the new thermostat with the spring side facing the engine, reassemble the housing, and refill the coolant before reconnecting the battery.
