3. Press the drive belt up from the smaller circumference pulley into the groove of the larger circumference pulley, and rotate the crankshaft pulley clockwise.

CAUTION:

• To prevent damaging the drive belt, do not stop rotation of the crankshaft pulley while pressing the drive belt up from the height difference of the water pump pulley to the groove of the pulley.

4. After drive belt installation, rotate the crankshaft pulley clockwise approx. halfway and verify that the water pump drive belt is installed correctly.

• If the rib of the drive belt and the groove of the pulley are not aligned, remove the drive belt and re-install it.
