FORD 2004 - Manual (Page 302)

• 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.
• Cover the highlighted areas to prevent water damage when cleaning
the engine.
