  9. Installation of the remaining components is in the reverse order of removal.
    • After installation refill engine coolant and check for leaks. Refer to "CHANGING ENGINE COOLANT " and "SYSTEM INSPECTION ".
      CAUTION: Do not spill coolant in the engine compartment. Use a shop cloth to absorb 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.
