Install chain tensioner cover and water pump cover.
1. Before installing, remove all traces of sealant from mating surface of water pump cover and chain tensioner cover using a scraper.
2. Apply a continuous bead of RTV Silicone Sealant or equivalent, to mating surface of chain tensioner cover and water pump cover. Refer to "RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS ".
Install water drain plug on water pump side of cylinder block. Refer to "CHANGING ENGINE COOLANT ".
Install idler pulley.
Idler pulley bolts: 28.4 N.m (2.9 kg-m, 21 ft-lb)
Installation of remaining components is in the reverse order of removal.

Refill engine coolant. Refer to "CHANGING 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.
