  Water pump bolts 9.6 N.m (0.98 kg-m, 85 in-lb)
Remove dust and foreign material completely from back side 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.

Tighten idler pulley bolts.
Idler pulley bolts : 34.8 N.m (3.5 kg-m, 26 ft-lb)
Installation of the remaining components is in the reverse order of removal.
- Refill engine coolant. Refer to "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.
