Repairing paint chips
Minor scratches or paint damage from road debris
may be repaired with the Ultra Touch Prep and
Finishing Kit (#F7AZ-19K507–BA), touch-up paint
(#ALBZ-19500–XXXXA), or aerosol paint spray
(#ALAZ-19500–XXXXA) from the Ford Car Care
Chemicals line. Please note that the part numbers
(shown as XXXX above) will vary with your vehicle's
specific coloring. Observe the application
instructions on the products.
Remove particles such as bird droppings, tree sap,
insect remains, tar spots, road salt and industrial
fallout immediately.
Cleaning the wheels
Wash with the same detergent as the body of your
vehicle. Do not use acid-based or alcohol-based
wheel cleaners, steel wool, fuel or strong detergents.
Never use abrasives that will damage the finish of
special wheel surfaces. Use a tar remover to remove
grease and tar.
The brushes used in some automatic car washes may
damage the finish on your wheels. Before going to a
car wash, find out if the brushes are abrasive.
Cleaning the engine
In order to identify your vehicle's engine, refer to
Identifying components in the engine
compartment in the Maintenance and Care chapter.
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.
Do not spray with cold water to avoid cracking
the engine block or other engine components.
