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 AdjustmentNBS003HQ
Belt tensioning is not necessary, as it is automatically adjusted by auto tensioner.

REMOVAL
Alternator, Water Pump and A/C Compressor Belt
1. Remove air duct (inlet). Refer to EM-177, "AIR CLEANER AND AIR DUCT" .
2. 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.
