● Refill engine coolant. Refer to CO-11, "REFILLING ENGINE COOLANT" .
● After starting engine, let idle for three minutes, then rev engine up to 3,000 rpm under no load to purge
air from the high-pressure chamber of the chain tensioner. The engine may produce a rattling noise.
This indicates that air still remains in the chamber and is not a matter of concern.
