Poly-V belt
Removal
PROCEDURE
1. Loosen the water pump pulley mounting bolts.
2. Loosen the alternator support nuts.
3. Loosen the alternator mounting bolt and remove the poly-V belt.

4. Remove the water pump pulley mounting bolts.
Tightening Torque:
Generator pivot bolt (A): 20–25 N·m Generator bolt (B): 15–22 N·m Generator bracket mounting bolt: 20–28 N·m
Inspection
Inspect the following items and replace them if defective.
PROCEDURE
1. Inspect the poly-V belt surface for damage and cracks.
2. Inspect the poly-V belt surface for oil and grease.
3. Inspect the poly-V belt surface for uneven wear.

4. Inspect the pulley surface for cracks or damage.
Installation
PROCEDURE
1. Install the pump pulley and secure it with the bolts.

2. Install the pump pulley and secure it with the bolts.
Poly-V Belt Tension Inspection and Adjustment
PROCEDURE
1. Check the condition of the poly-V belt and its routing on the pulleys.
Check that the ribs of the poly-V belt are correctly seated in the pulley grooves.
If the poly-V belt makes abnormal noise during operation, check the belt for wear and damage, as well as the pulley contact surfaces.

2. Measure the alternator drive belt tension with a special tool. If the special tool is not available, check the belt tension by pressing on the belt with a force of 100 N (10 kg) at a point equidistant from the pulleys and measure the belt deflection.
Belt deflection for generator drive belt tension check:
New belt: 7.5–9.0 mm / 64–73 kg
Used belt: 9.0–10.4 mm / 39 kg
Check: 5.0–6.0 mm / 34–49 kg
Belt deflection for generator and power steering pump drive belt tension check:
New belt: 8 mm
Used belt: 6.0–7.0 mm
Belt deflection for generator and air conditioner drive belt tension check:
New belt: 6.0–9.0 mm
Used belt: 9.0–10.0 mm

A used belt is a belt that has run on the engine for more than 5 min.
Measuring tension with a special tool
PROCEDURE

1. When measuring the tension of the V-ribbed belt, the tool must not touch other engine components.
2. Adjust the deflection or tension of the power steering pump belt.
3. Tighten the adjusting bolt.
4. Turn the crankshaft several revolutions.

5. Check the belt tension and, if necessary, repeat the adjustment.
