These belts are prone to failure due to aging and other factors and hence require frequent inspections and adjustments to avoid causing serious damage to the engine. The number of belts installed depends on the accessories such as the generator, smog pump, power steering pump, water pump, fan, and air conditioning compressor. Determine if you need to replace by examining these elements: cracks, separation or fraying is visible on both sides of the belt. Exert pressure on the middle part between pulleys and observe deflection in order to verify whether it is tight enough or not. Adjustment can be done by shifting the accessory driven by belt along its bracket while loosening adjustment or strap bolt and pivot bolt. Some items may need to be moved closer or farther from the engine when adjusting these belts. Take extreme caution when using a pry bar for leverage so as not to damage either component or the part against which it is being pried.

Drive belts or V- belts positioned at the front of the engine are useful in the operation of the car and more to its subparts. Owing to the function as well as material of construction of these belts, they wear out with time and ought to be checked periodically for potential breakdown and Signs of wear, in an effort to prevent major failure of the engine. The number of belts depends on the accessories that are fitted to a car, and these may include the generator, A.I.A. smog pump, power steering pump, water pump, fan belt, and air conditioning compressor; a single belt may drive several accessories depending on the location of the pulleys. To inspect the belts, turn off the engine and open the hood and check for deep cracks, cuts, curting, glazing and more over else twist the belts to check on the inner side. Tension is measured by pressing of the belt halfway between the pulleys; belt from 7 to 11 inches should deflect ¾ inch while the belt from 12 to 16 inches should deflect ½ inch. If adjustment is required, the belt-driven accessory may be moved to its bracket utilising the adjustment & pivot bolts. On releasing pull the component in such a manner that either the belt will tighten or loosen and keep it in fixed position to find out the tension exerted. When the correct tension is reached on both gauges the bolts will be secured and the tension checked before final tightening. Adjustment may require the use of pry bar from where leverage is required while exercising a lot of care since this is likely to result to damage of the component or even the surface against which it is placed.
