Drive Belt: Service and Repair

Drive Belt Replacement

On-Vehicle Inspection




1. Inspect the V-ribbed belt for wear, cracks or other signs of damage.
If any of the following defects is found, replace the V-ribbed belt.

* The belt is cracked.
* The belt is worn out to the extent that wires are exposed.
* The belt has chunks missing from the ribbed grooves.





Note: Check by hand to confirm that the belt has not slipped out of the grooves on the bottom to the pulley. If it has slipped out, replace the V-ribbed belt. Install a new V-ribbed belt correctly.

2. Check that the belt fits properly in the ribbed grooves.




3. On vehicles equipped with air conditioning, check the belt deflection and tension in positions shown (1, 2).




4. On vehicles without air conditioning, check the belt deflection and tension in position shown (1).
5. If the belt deflection is not as specified, adjust it. Refer to Engine Mechanical Specifications (Specifications).

* When inspecting the belt deflection, apply 98 N (10 kgf) tensile force to it.
* After installing a new belt, run the engine for approximately 5 minutes and then re-adjust the tension to (new belt) specifications.
* Check the V-ribbed belt deflection and tension at the specified point.
* V-ribbed belt tension and deflection should be checked after 2 revolutions of the engine.
* V-ribbed belt tension and deflection should be checked at TDC crank angle and cold condition.
* When adjusting a belt, adjust its deflection and tension to the intermediate values of the specification.
* When reinstalling a belt which has been used for over 5 minutes, adjust its deflection and tension to the used belt specification.
* When using a belt tension gauge, confirm its accuracy by using a master gauge first.

Removal Procedure




1. Remove the engine cover. Refer to Engine Mount Replacement (Service and Repair).
2. Remove the engine under cover RH.
3. Remove the V-ribbed belt.

1. Loosen bolts (2, 4).
2. Loosen bolt (3) then remove the V-ribbed belt.

Installation Procedure




1. Install the V-ribbed belt

Caution: Refer to Fastener Caution (Fastener Caution).

2. Adjust the V-ribbed belt

1. Turn bolt 3 to adjust the tension of the V-ribbed belt.
2. Install bolts 2 and 4 and tighten.

* Bolt 2 to 19 Nm (14 lb ft).
* Bolt 4 to 43 Nm (32 lb ft).

3. Inspect the V-ribbed belt.
4. Install the engine under cover RH.
5. Install the engine cover. Refer to Engine Mount Replacement (Service and Repair).
