Cleaning Cleaning the engine Engines are more efficient when they are clean because grease and dirt buildup keep the engine warmer than normal. When washing: • The engine must be cool to the touch before spraying with water. • Never spray a hot engine with cold water, as damage to the engine block or engine components may occur. • Use caution when using a selfĆserve power washer (1000psi maximum pressure) to clean the engine, as the highĆpressure fluid could penetrate the sealed parts and cause damage. • Never apply anything to any exposed belts in the engine compartment, including the belt dressing. For general cleaning of the engine and engine compartment, spray Engine Shampoo and Degreaser (FYAZĆ19A536ĆA) on all parts that require cleaning and pressure rinse the area with cool water. Never wash or rinse the engine while it is running; water in the running engine may cause internal damage. 256
