Open the drain cocks on the engine block andradiator (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 scalinginside the radiator, use a commercial scale re-mover and flush the cooling system thor-oughly before adding fresh coolant.Use a pre-mixed 50/50 solution of antifreeze (ethyl-ene glycol) and distilled water to refill the coolingsystem.IMPORTANT: The solution of antifreeze and watermust be thoroughly pre-mixed before putting it in theengine. Adding pure antifreeze into the radiator maycause damage to the engine from overheating.IMPORTANT: Maintain proper coolant level in theradiator and coolant recovery tank.
