  If your Kubota Tractor engine is overheating, start by checking the engine oil and coolant levels and replenish if insufficient. Inspect the fan belt for damage or improper tension and replace or adjust as needed. Clean any dust or debris from the radiator net and fins. If the inside of the radiator or coolant flow route is corroded, clean or replace them. A defective radiator cap or damaged radiator hose should also be replaced. Avoid overload running by reducing the load. A defective head gasket should be replaced, and incorrect injection timing should be adjusted. Ensure you are using the specified fuel.
