Maintenance and care
Never apply any cleaning chemical to hot or warm wheel rims or covers.
Clean wheel rims and covers with Detail Wash (ZC-3–A), which is
available from your authorized Ford, Lincoln or Mercury dealer. Spray
cleaner on cool wheel rims or covers and allow to set for 2–5 minutes.
Agitate the area with a sponge and rinse off with plenty of water.
Use Extra Strength Tar and Road Oil Removal (B7A-19520–AA),
available from your authorized Ford, Lincoln or Mercury dealer, in order
to remove tar and grease from wheel rims and covers.
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 self-serve power washer (1000 psi 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 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.
