Engine Cooling System
Radiator Screen and Cooling Fins
To prevent the engine from overheating and possible engine damage, clean grass clippings, chaff, and dirt from the fine mesh radiator intake screen daily. In certain mowing conditions (dry grass, leaves, tree “cotton”, etc.), it may be necessary to check and clean the screen several times during use to prevent engine overheating.
1.Lift to remove the screen. To clean the screen, wash with soapy water or blow out with com- pressed air.
2.Inspect the radiator cooling fins for material lodged in this area which would restrict cooling airflow. Use pressurized air or water to clean.
DO NOT use any tool, like a screwdriver or knife, to clean material out of the fins as this may damage the cooling fins. DO NOT use cold water on a hot radiator.
NOTE: Directing pressurized air or water from the fan side of the radiator outward is recom- mended to dislodge material packed on the out- side of the cooling fins. DO NOT use cold water on a hot radiator.
WARNING
Radiator and engine parts can become extremely hot during operation. Wear gloves and avoid touching hot parts while cleaning the radiator screen and cleaning debris away from the engine and cooling system.
Flushing Radiator and Changing Coolant
Change engine coolant every year. Drain the coolant from the engine and radiator:
1.Remove the radiator cap.
2.Open the drain cocks on the engine block and radiator (see the Kubota Owner's Manual for lo- cation of the drain cocks). Also, drain the cool- ant recovery tank.
3.If there is any indication of deposits or scaling inside the radiator, use a commercial scale re- mover and flush the cooling system thor- oughly before adding fresh coolant.
Use a
IMPORTANT: The solution of antifreeze and water must be thoroughly
IMPORTANT: Maintain proper coolant level in the radiator and coolant recovery tank. The coolant level should be maintained between FULL and LOW marks on the coolant recovery tank. Recheck the coolant level after the first time the engine has been operated after filling the coolant system (it would be normal to add a little coolant after initial operation).
