Note: Location of drive belts for water pump, generator. power steering pump and air conditioning compressor varies according to the model - see Fig. 2.5, 2.6 and 2.7. The water pump and alternator or power steering pump are driven by a single belt, depending on the model.
Adjustment
1. First check the entire length of the belt, cleaning off any dirt. Replace the belt if there are cracks, tears or other damage.
2. To check the belt tension, apply a force of 98N in the places indicated in Fig. 2.5, 2.6 or 2.7 and accurately measure the belt deflection at this point.

3. If the measured deviation is greater than the specified limit, tighten the belt as described below until the deviation is reduced to the specified adjustment range. If a new belt is being installed, note that in some cases a higher tension is used for initial adjustment.
Alternator drive belt
4. To adjust the alternator drive belt, loosen both pivot bolts under the alternator, loosen the adjuster locking bolt, tighten (or loosen if necessary) regulator nut or bolt. After installation, tighten the bolts.
Power steering pump drive belt
5. To adjust the power steering pump drive belt, loosen the pivot bolt under the pump, loosen the adjuster lock bolt, tighten (or loosen if necessary) regulator nut (photo). Then tighten the bolts.

Air Conditioner Compressor Drive Belt
6. To adjust the air conditioning compressor drive belt, loosen the pulley lock nut, tighten (or loosen if necessary) adjuster bolt, which is located under the idler gear assembly. After adjustment, tighten the locknut with the tightening torque specified in the Specifications.
Removal and installation
Note: In some cases, it is necessary to first remove another drive belt before the required belt can be removed. For example, to remove the power steering pump drive belt, you must first remove the alternator belt (or air conditioning compressor).
7. To remove the alternator or power steering pump belt, loosen the alternator pivot bolt, loosen the adjuster retaining bolt, and unscrew the adjuster nut or bolt. Turn the generator or pump toward the engine and remove the belt from the pulleys.
8. To remove the air conditioning compressor drive belt, loosen the locknut and adjuster bolt, and remove the belt from the pulleys.
9. Installation is carried out in reverse order. Adjust the belt tension as described above.
