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.
• 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.
PLASTIC (NON-PAINTED) EXTERIOR PARTS
Use only approved products to clean plastic parts. These products are
available from your authorized dealer.
• For routine cleaning, use Motorcraft Detail Wash (ZC-3–A).
• If tar or grease spots are present, use Motorcraft Bug and Tar
Remover (ZC-42).
• For plastic headlamp lenses, use Motorcraft Ultra Clear Spray Glass
Cleaner (ZC-23).
