The drive belts, also known as V-belts, are located at the front of the engine and are crucial for the proper functioning of the car and its components. These belts are prone to failure over time and should be inspected and adjusted regularly to prevent significant engine damage. The number of belts used depends on the accessories installed, such as the generator alternator, A.I.R. smog pump, power steering pump, water pump, fan, and air conditioning compressor. To inspect the belts, open the hood with the engine off and check for cracks, separation, fraying, and glazing. Both sides of the belts should be examined, requiring the twisting of the belt to check the underside. The tension of each belt can be checked by pushing on it at a distance halfway between the pulleys. The deflection of the belt should be within a specific range based on the distance between the pulleys. If adjustment is necessary, the belt-driven accessory can be moved on its bracket. This adjustment involves loosening the strap and pivot bolts, moving the component away from or towards the engine to tighten or loosen the belt, and then tightening the bolts once the correct tension is achieved. It may be necessary to use a pry bar to gain leverage while adjusting the belt, but caution must be taken to avoid damaging the component or part being pried against.
