Lincoln 2010 Navigator Automobile User Manual


 
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. Chemical-strength cleaners, or cleaning
chemicals, in combination with brush agitation to remove brake dust
and dirt, could wear away the clearcoat 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 Motorcraft Bug and Tar Remover
(ZC-42), 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.
Do not spray a hot engine with cold water to avoid cracking the
engine block or other engine components.
Spray Motorcraft Engine Shampoo and Degreaser (ZC-20) on all parts
that require cleaning and pressure rinse clean. In Canada, use
Motorcraft Engine Shampoo (CXC-66-A).
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.
