Cleaning the 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 with cold water to
avoid cracking the engine block
or other engine components.
• 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.
