CLEAN ENGINE
1. Cap or plug all openings on engine. If electrical
components (starting motor, alternator, etc...) are not
removed prior to cleaning, cover with plastic and tape
securely to prevent moisture from entering.
2. Steam-clean engine thoroughly.
IMPORTANT: Never steam-clean or pour cold water
