Checking Drive BeltsABS006I7
WARNING:
Be sure to perform when engine is stopped.

Remove air duct (inlet) when inspecting drive belt for alternator, water pump and A/C compressor.

Remove front engine undercover with power tool when inspecting power steering oil pump belt.

Make sure that indicator (single line notch) of each auto tensioner is within the allowable working range
(between three line notches).
NOTE:

Check auto tensioner indication when engine is cold.

When new drive belt is installed, the range should be “A”.

The indicator notch is located on the moving side of auto tensioner for alternator, water pump and A/C
compressor belt, while it is found on the fixed side for power steering oil pump belt.

Visually check entire belt for wear, damage or cracks.

If the indicator is out of allowable working range or belt is damaged, replace belt.
Tension AdjustmentABS006I8
Belt tensioning is not necessary, as it is automatically adjusted by auto tensioner.
Removal and InstallationABS006I9
REMOVAL
Alternator, Water Pump and A/C Compressor Belt
1. Remove air duct (inlet). Refer to EM-172, "AIR CLEANER AND AIR DUCT" .
2. Front engine undercover with power tool.
3. With box wrench, and while securely holding the hexagonal part
in pulley center of auto tensioner, move wrench handle in the
direction of arrow (loosening direction of tensioner).
CAUTION:
Avoid placing hand in a location where pinching may occur
if the holding tool accidentally comes off.
4. Under the above condition, insert a metal bar of approximately 6
mm (0.24 in) in diameter (hexagonal bar wrench shown as
example in the figure) through the holding boss to lock auto ten-
sioner pulley arm.

Leave auto tensioner pulley arm locked until belt is installed
again.
