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.
