DRIVE BELTSPFP:02117
Checking Drive BeltsEBS00KN7
WARNING:
Be sure to perform this step when the engine is stopped.

Make sure that the indicator (single line notch on fixed side) of drive belt auto-tensioner is within the pos-
sible use range (between three line notches on moving side).
NOTE:

Check the drive belt auto-tensioner indicator (single line notch on fixed side) when engine is cold.

When new drive belt is installed, the indicator (single line notch on fixed side) should be within the
range “A” in the figure.

Visually check entire belt for wear, damage or cracks.

If the indicator (single line notch on fixed side) is out of the possible use range or belt is damaged, replace
drive belt.
Tension AdjustmentEBS00KN8
Belt tensioning is not necessary, as it is automatically adjusted by drive belt auto-tensioner.
Removal and InstallationEBS00KN9
REMOVAL
1. Remove splash guard on RH undercover.
2. 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.
3. Insert a rod approximately 6 mm (0.24 in) in diameter such as
short-length screwdriver into the hole of the retaining boss to fix
drive belt auto-tensioner pulley.
4. Loosen drive belt from water pump pulley in sequence, and
remove it.
