The generator is a belt-driven component that is driven directly off of the crankshaft. Maintaining the proper tension on this belt is crucial to prevent excessive strain on the belt, as well as the generator's shafts and bearings. To check the tension of the belt, find the longest stretch and move it back and forth to gauge its slack; the distance should be about 13 mm.

The drive belts, commonly referred to as V-belts, are located at the front of the engine and are important for the car and its components to work well. These belts tend to fail over time and hence should be checked regularly and adjusted to prevent serious damage to the engine. The number of belts required depends on equipment installed such as the power steering pump, water pump, generator and air conditioning compressor. To check the belts, open the hood with the engine off and find them on the right side of the engine compartment. Look for cracks, separation, fraying, or glazing that make a belt shiny looking. Twist each belt from both sides to see if there is any wear on it. By pushing halfway between pulleys one can test each belt's tensioner. The amount of deflection should be ¾ inch for 7-11 inch pulley center distances and ½ inch for 12-16 inch pulley center distances. If needed an accessory that is driven by a belt can be repositioned on its bracket. A pry bar may be needed for leverage but caution must be exercised in order not to harm either component or part being pried against it.

The same belts driving both the generator and power steering pump (when equipped) also drive this water pump, which is additionally linked via an A/C compressor belt. The necessary process to follow in adjusting or replacing any of these belts is as stated below each respective component.

In case of the V6 engine, the air conditioning compressor is driven directly off of the crankshaft as a belt-driven component, and off of the water pump pulley in case of L4 engine. The belt must be tense enough to avoid twisting it excessively on its shafts and bearings. To identify the tension, disconnect the negative battery cable then find out which part of the belt can move most freely without resistance. This stretch should only move about f-in (13 mm). If it moves more than that, you need to adjust it by moving the compressor outwards from the engine through loosening up adjusting bolts for the compressor and mounting bolts. Tighten bolts and recheck adjustment. However, in case NC compressor drive belt is frayed or cracked, it should be replaced. In case equipped with one remove power steering drivebelt first from L4 engines then generator belt. Remove generator belt first from VG engines then power steering pump drivebelt if equipped. Loosen adjusting bolts for NC compressor then move towards engine until loose enough to remove from pulleys. Place a new belt over top of NC compressor, water pump, and crankshaft (V6) and adjust/ tighten accordingly. Finally reinstall generator and power steering pump belts/adjust/tighten them.

In V6 engines, the air conditioning compressor is driven directly off of the crankshaft.

The water pump is driven by the same belts that drive the generator and power steering pump (when equipped), and is also connected to the A/C compressor belt.

Drive belts, also known as V-belts, are located at the front of the engine.

To adjust or replace any of these belts, the procedure described under the appropriate accessory is used.

In V6 engines, the air conditioning compressor is driven directly off of the crankshaft.

Maintaining proper tension on the generator belt is crucial to prevent excessive strain on the belt, as well as the generator's shafts and bearings.

To adjust the generator belt, loosen the generator's adjusting and mounting bolts, move the generator away from the engine to adjust the belt, and then tighten the bolts.
