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
威
Engine Shampoo and Degreaser (ZC-20) on all
parts that require cleaning and pressure rinse clean. In Canada, use
Motorcraft
威
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 hot or running; water in the
running engine may cause internal damage.
•
Never wash or rinse any ignition coil, spark plug wire or spark plug
well, or the area in and around these locations.
PLASTIC (NON-PAINTED) EXTERIOR PARTS
Use only approved products to clean plastic parts. These products are
available from your authorized dealer.
•

威
