Remove dust and foreign material completely from backside of chain tensioner and from installation area of rear timing chain case.
Turn the crankshaft pulley approximately 20° clockwise so that the timing chain on the timing chain tensioner side is loose.
NOTE: When installing the timing chain tensioner, engine oil should be applied to the oil hole and tensioner.

Install water drain plug on water pump side of cylinder block.
Install idler pulley.
1. Idler pulley bolts : 25 - 31 N.m (2.5 - 3.2 kg-m, 18 - 23 ft-lb)
Installation of remaining components is in the reverse order of removal.

Refill 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.
