INSPECTION



See Figures 1, 2, 3, 4, 5 and 6

Inspect the belts for signs of glazing or cracking. A glazed belt will be perfectly smooth from slippage, while a good belt will have a slight texture of fabric visible. Cracks will usually start at the inner edge of the belt and run outward. All worn or damaged drive belts should be replaced immediately. It is best to replace all drive belts at one time, as a preventive maintenance measure, during this service operation.

ADJUSTMENT



Alternator

See Figures 7 and 8

To adjust the tension of the alternator drive belt, loosen the pivot and mounting bolts on the alternator. These bolts should be either 12mm or 14mm. Using a wooden hammer handle or a broomstick, or even your hand if you're strong enough, move the alternator one way or the other until the tension is within acceptable limits.


CAUTION
Never use a screwdriver or any other metal device such as a prybar, as a lever when adjusting the alternator belt tension!

Tighten the mounting bolts securely. If a new belt has been installed, always recheck the tension after a few hundred miles of driving.

Alternator belt tension on all other engines is adjusted by means of a tension adjusting bolt with is usually a 12mm or 14mm. Loosen the alternator pivot bolt and the locking bolt, then turn the tension adjusting bolt until proper tension is achieved.

Tighten the mounting bolts securely. If a new belt has been installed, always recheck the tension after a few hundred miles of driving.

Air Conditioning Compressor

See Figures 9 and 10

Tension on the air conditioning compressor belt is adjusted by means of an idler pulley. Loosen the lockbolt and then turn the adjusting bolt on the idler pulley until the desired tension is achieved. Retighten the idler pulley lockbolt. All of the bolts are either a 12mm or 14mm.

Tighten the lockbolt securely. If a new belt has been installed, always recheck the tension after a few hundred miles of driving.

Power Steering Pump

See Figure 11

On some models, tension on the power steering pump belt is adjusted by means of an idler pulley. Loosen the lockbolt and then turn the adjusting bolt on the idler pulley until the desired tension is achieved. Retighten the idler pulley lockbolt. All of these bolts are usually a 12mm or 14mm.

Tighten the lockbolt securely. If a new belt has been installed, always recheck the tension after a few hundred miles of driving.

Power steering pump belt tension on other models is adjusted by means of a tension adjusting bolt. Loosen the power steering pump pivot bolt and then turn the tension adjusting bolt until proper tension is achieved.

REMOVAL & INSTALLATION



See Figures 12, 13, 14, 15 and 16

If a belt must be replaced, the driven unit must be loosened and moved to its extreme loosest position, generally by moving it toward the center of the motor. After removing the old belt, check the pulleys for dirt or built-up material which could affect belt contact. Carefully install the new belt, remembering that it is new and unused - it may appear to be just a little too small to fit over the pulley flanges. Fit the belt over the largest pulley (usually the crankshaft pulley at the bottom center of the motor) first, then work on the smaller one(s). Gentle pressure in the direction of rotation is helpful. Some belts run around a third or idler pulley, which acts as an additional pivot in the belt's path. It may be possible to loosen the idler pulley as well as the main component, making your job much easier. Depending on which belt(s) you are changing, it may be necessary to loosen or remove other interfering belts to get at the one(s) you want.

When buying replacement belts, remember that the fit is critical according to the length of the belt, the width of the belt, the depth of the belt and the angle or profile of the V shape (always match up old belt with new belt if possible). The belt shape should exactly match the shape of the pulley; belts that are not an exact match can cause noise, slippage and premature failure.

After the new belt is installed, draw tension on it by moving the driven unit away from the motor and tighten its mounting bolts. This is sometimes a three- or four-handed job; you may find an assistant helpful. Make sure that all the bolts you loosened get retightened and that any other loosened belts also have the correct tension. A new belt can be expected to stretch a bit after installation so be prepared to re-adjust your new belt.

After installing a new belt, run the engine for about 5 minutes and then recheck the belt tension.
