•Do not allow paint sealant to come in contact with any non-body
(low-gloss black) colored trim, such as grained door handles, roof
racks, bumpers, side moldings, mirror housings or the windshield cowl
area. The paint sealant will “gray” or stain the parts over time.
PAINT CHIPS
Your authorized dealer has touch-up paint to match your vehicle’s color.
Take your color code (printed on a sticker in the driver’s door jamb) to
your authorized dealer to ensure you get the correct color.
•Remove particles such as bird droppings, tree sap, insect deposits, tar
spots, road salt and industrial fallout before repairing paint chips.
•Always read the instructions before using the products.
ALUMINUM WHEELS AND WHEEL COVERS
Aluminum wheels and wheel covers are coated with a clear coat paint
finish. In order to maintain their shine:
•Clean weekly with MotorcraftWheel and Tire Cleaner, which is
available from your authorized dealer. Heavy dirt and brake dust
accumulation may require agitation with a sponge. Rinse thoroughly
with a strong stream of water.
•
Never apply any cleaning chemical to hot or warm wheel rims or covers.
•Some automatic car washes may cause damage to the finish on your
wheel rims or covers. Industrial-strength (heavy-duty) cleaners, or
cleaning chemicals, in combination with brush agitation to remove
brake dust and dirt, could wear away the clear coat finish over time.
•Do not use hydrofluoric acid-based or high caustic-based wheel
cleaners, steel wool, fuels or strong household detergent.
•To remove tar and grease, use MotorcraftBug and Tar Remover ,
available from your authorized dealer.
ENGINE
Engines are more efficient when they are clean because grease and dirt
buildup keep the engine warmer than normal. When washing:
•
Take care when using a power washer to clean the engine. The
high-pressure fluid could penetrate the sealed parts and cause damage.
Note:To prevent damage to the engine control module, never
spray-wash it directly. Never spray any connector.
•Do not spray a hot engine with cold water to avoid cracking the
engine block or other engine components.
