To check the belt tension, apply 110 N (25 lb) of force midway between the pulleys. Correctly adjusted belts will deflect 14 to 20 mm (1/2 to 3/4 inch).
In order to adjust the alternator belt, loosen bracket bolt (1) and mounting bolt (3) on the alternator bracket.
To achieve the correct adjustment, move the alternator inward or move the alternator outward, as required.
If necessary, use a pry bar in the square hole (2) in the alternator bracket.
Tighten mounting bolt (3) and bracket bolt (1) .
If new belts are installed, check the belt and adjustment again after 30 minutes of engine operation at the rated speed.
Check the position of the fan shroud. Adjust the position of the fan shroud so that the fan will not rub against the shroud. Maintain a 9.4 mm (0.38 inch) clearance between the fan and the shroud.
Close the engine compartment.
