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.
