CLEANING THE ENGINE
Engines are more efficient when they are clean because grease and dirt
buildup keep the engine warmer than normal. When washing:
²The engine must be cool to the touch before spraying with water.
²Never spray a hot engine with cold water, as damage to the
engine block or engine components may occur.
²Use caution when using a self-serve power washer (1000psi maximum
pressure) to clean the engine, as the high-pressure fluid could
penetrate the sealed parts and cause damage.
²Never apply anything to any exposed belts in the engine
compartment, including belt dressing.
For general cleaning of the engine and engine compartment, spray
Engine Shampoo and Degreaser (F4AZ-19A536±A) on all parts that
require cleaning and pressure rinse the area with cool water.
²Cover the highlighted areas to prevent water damage when cleaning
the engine.
²Never wash or rinse the engine while it is running; water in the
running engine may cause internal damage.
