   Apply sealant (PN 08826-00100) to the water pump

WARNING

Parts must be assembled within 5 minutes of application. Otherwise the material must be removed and reapplied.

Water pump. Tighten the bolts to 14 ft. lbs. (20 Nm).

No. 2 oil cooler hose

Thermostat

Left camshaft timing pulley. Tighten the pulley bolt to 81 ft. lbs. (110 Nm).

1. Set the No. 1 cylinder to TDC of the compression stroke.
2. Connect the timing belt to the left camshaft timing pulley. Check that the installation mark on the timing belt is aligned with the end of the No. 1 timing belt cover, as follows:
   1. Using Variable Pin Wrench Set 09960-01000, slightly turn the left camshaft timing pulley clockwise. Align the installation mark on the timing belt with the timing mark of the camshaft timing pulley and hang the timing belt on the left camshaft timing pulley.
