The drive belts, also known as V-belts, are located at the front of the engine and are crucial for the overall operation of the engine and accessories. These belts are prone to failure over time and should be inspected and adjusted periodically to prevent significant engine damage. The number of belts used depends on the accessories installed, such as the alternator, power steering pump, water pump, and air conditioning compressor. To inspect the belts, locate them at the front of the engine with the engine off. Check for cracks, separation, fraying, and glazing on both sides of each belt. Also, inspect the pulleys for nicks, cracks, distortion, and corrosion. The tension of each belt can be checked by pushing on it at a distance halfway between the pulleys. If adjustment is needed, it can be done by moving the belt-driven accessory on the bracket. Each component usually has an adjusting bolt and a pivot bolt that must be loosened to enable movement. After loosening the bolts, move the component away from or toward the engine to tighten or loosen the belt, respectively. Use caution when using a pry bar to move the accessory. To replace a belt, follow the same adjustment procedures but slip the old belt off the pulley and remove it. It is recommended to replace all belts at the same time. When purchasing new belts, bring the old ones for a direct comparison in length, width, and design.
