Cleaning • Never spray a hot engine with cold water, as damage to the engine block or engine components may occur. • Use 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. • 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 (F4AZ-19A536-A) on all parts that require cleaning and pressure rinse the area with cool water. • Cover the highlighted areas to prevent water damage when cleaning the engine. • Never wash or rinse the engine while it is running; water in the running engine may cause internal damage. WASHING NON-PAINTED PLASTIC EXTERIOR PARTS Use Detail Wash (ZC-3-A) for routine cleaning. If tar or grease spots are present, clean with Extra Strength Tar and Road Oil Removal (B7A-19520-AA). Use only approved products to clean plastic parts. These products are available from your authorized Ford, Lincoln or Mercury dealer. WASHING THE EXTERIOR LAMPS In order to avoid scratching the plastic lamps, do not use dry paper towels, non-approved chemical solvents or abrasive cleaners. 212
