Maintenance and care
Cleaning the engine
Engines are more efficient when
they are clean because grease and
dirt buildup act as insulators and
keep the engine warmer than
normal. Follow these guidelines to
clean your engine:
• 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.
• Cover the alternator 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.
