ComponentINFOID:0000000005398110
Checking Drive BeltsINFOID:0000000005398111
WARNING:
Be sure to perform this step
when the engine is stopped.
NOTE:
On vehicles not equipped with A/C, there is an idler pulley in the position for the drive belt routing.
• Make sure that the indicator (notch on fixed side) of drive belt auto-tensioner is within the possible use
range.
NOTE:
• Check the drive belt auto-tensioner indication when the engine is cold.
• When new drive belt is installed, the indicator (notch on fixed side) should be within the range.
• Visually check entire drive belt for wear, damage or cracks.
• If the indicator (notch on fixed side) is out of t he possible use range or belt is damaged, replace drive belt.
Tension AdjustmentINFOID:0000000005398112
Belt tension is not necessary, as it is automatically adjusted by drive belt auto-tensioner.
Removal and InstallationINFOID:0000000005398113
REMOVAL
1. Remove fender protector (RH). Refer to EI-24, "Removal and Installation".
2. Hold the hexagonal part (A) of drive belt auto-tensioner (1) with a wrench securely. Then move the wrench handle in the direc-
tion of arrow (loosening direction of tensioner).
WARNING:
Never place hand in a location where pinching may occur if
the holding tool acci dentally comes off.
CAUTION:
Do not loosen the auto-tensione r pulley bolt. (Do not turn it
counterclockwise.) If turned counterclockwise, the com-
plete auto-tensioner must be replaced as a unit, including
pulley.
3. Insert a rod such as short-length screwdriver approximately 6 mm (0.24 in) in diameter into the hole (B) of t he retaining boss to fix drive belt auto-tensioner.
• Leave tensioner pulley arm locked until belt is installed again.
4. Remove drive belt.

1. Install drive belt.
CAUTION:
Confirm drive belt is completely set to pulleys.
2. Release drive belt auto-tensioner, and apply tension to drive belt. WARNING:
Never place hand in a location where pinching m ay occur if the holding tool accidentally comes
off.
CAUTION:
Make sure no engine oil, working fluid and engine coolant are adhe red to drive belt and each pul-
ley groove.
3. Turn crankshaft pulley clockwise several times to equalize tension between each pulley.
4. Confirm tension of drive belt at indicator (notch on fixed side) is within the possible use range. Refer to
EM-132, "
Checking Drive Belts".
5. Install fender protector (RH). Refer to EI-24, "
Removal and Installation".
