Use a hoist or get assistance when lifting components

that weigh 23 kg (50 lb.) or more. Make sure all lifting

devices such as chains, hooks, or slings are in good

condition and are of the correct capacity. Make sure

bar when necessary. The lifting hooks MUST NOT be

side loaded. Failure to follow these warnings may

result in personal injury.

from the exhaust side of the engine).

Note: On WIA, bring the valve cover towards the radiator

to remove. On WG, it is necessary to remove the engine

cover (doghouse).
