Product Information

An accessory drive belt, also referred to as a serpentine belt, functions by transferring power from the engine crankshaft to various accessories like the alternator, water pump, power steering pump, and air conditioning compressor. Essentially driving these rotating assembles through a series of pulleys with the belt's rotation. It is important to check the belt for cracks, fraying, or excessive wear during routine maintenance, keeping in mind most manufacturers recommend replacing the accessory drive belt at specified mileage intervals, typically between 50,000 and 100,000 miles. Proper tensioning of the belt is also crucial, so while servicing or inspecting an accessory drive belt, it is important to also inspect the belt tensioner and supporting idler pulleys.

• Wear and tear: Over time, the belt can become cracked, frayed, or glazed, causing it to slip on the pulleys.
• Misalignment: If pulleys are not properly aligned, the belt can rub against them unevenly, causing wear and noise.
• Tension issues: Incorrect belt tension can lead to slipping or excessive strain on the belt and its components.
• Contamination: Engine oil, coolant, or debris can degrade the belt material
• Excessive Noise: Squealing noise, especially when starting the engine
