INSTALLATION
1. Hook the auxiliary drive belt onto all of the pulleys except for the water pump pulley. Hook the drive belt onto water pump pulley last.

CAUTION: Confirm belts are completely set on the pulleys.

2. Release tensioner, and apply tensions to belt.

CAUTION:

*Avoid placing hand in a location where pinching may occur if the holding tool accidentally comes off.
*Do not loosen the auto-tensioner pulley bolt. (Don't turn it counterclockwise. If turned counterclockwise, the complete auto-tensioner must be replaced as a unit, including pulley.

3. Turn crankshaft pulley clockwise several times to equalize tension between each pulley.
4. Confirm tensions of belt at indicator is within the allowable use range.

This is a tricky one as the clearence between the pulleys and the frame are tight. The easiest way to get a little room is to take off the passanger front wheel and remove the plastic cover that covers the oil filter area. Now work the belt from the top and bottom this will make it a bit easier.
