INSTALLATION
1. With box wrench, and while securely holding the hexagonal part
in center of drive belt auto-tensioner pulley, move the wrench
handle in the direction of arrow (loosening direction of ten-
sioner).
CAUTION:

Avoid placing hand in a location where pinching may
occur if the holding tool accidentally comes off.

Do not loosen the hexagonal part in center of drive belt
auto-tensioner pulley (Do not turn it counterclockwise). If
turned counterclockwise, the complete drive belt auto-
tensioner must be replaced as a unit, including the pul-
ley.
2. Insert a rod approximately 6 mm (0.24 in) in diameter such as short-length screwdriver into the hole of
retaining boss to fix drive belt auto-tensioner pulley.
3. Hook drive belt onto all pulleys except for water pump, and then onto water pump pulley finally.
CAUTION:

Confirm belt is completely set to pulleys.

Check for engine oil, working fluid and engine coolant are not adhered to drive belt and each
pulley groove.
4. Release drive belt auto-tensioner, and apply tension to drive belt.
5. Turn crankshaft pulley clockwise several times to equalize tension between each pulley.
6. Confirm tension of drive belt at indicator (notch on fixed side) is within the possible use range. Refer to
EM-14, "
Checking Drive Belts" .
Removal and Installation of Drive Belt Auto-TensionerBBS0058V
CAUTION:
The complete drive belt auto-tensioner must be replaced as a unit, including the pulley.
REMOVAL
1. Remove splash guard (RH).
2. Remove drive belt. Refer to EM-14, "
