Accessory Drive Belt Kit (Serpentine Belt Kit)
This kit includes everything needed to replace the primary wear components of your accessory drive system. Each kit comes complete with a new serpentine belt, drive belt tensioner shock, tensioner pulley, two idler pulleys, and all required hardware.

The accessory drive belt—commonly known as a serpentine belt—delivers power from the engine’s crankshaft to essential components such as the alternator, water pump, power steering pump, and air conditioning compressor. It drives these systems through a network of pulleys synchronized by the belt’s rotation.

Regular inspection of the belt is important. Look for cracking, fraying, glazing, or other signs of wear. Most manufacturers recommend replacing the belt every 50,000 to 100,000 miles. Proper belt tension is equally critical, so it’s advisable to inspect the belt tensioner and idler pulleys any time the belt is serviced.

Symptoms of Accessory Drive Belt Kit Failure

• Wear and Tear: Cracking, glazing, or fraying can cause the belt to slip. 
•   Pulley Misalignment: Misaligned pulleys lead to uneven wear and unwanted noise. 
•   Improper Tension: Too much or too little tension can result in belt slip or premature component failure. 
•   Contamination: Oil, coolant, or debris can weaken the belt material. 
•   Excessive Noise: A squealing sound, especially at start-up, often indicates belt or tensioner issues.
