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.

This tensioner helps maintain the correct tension and routing of the accessory (serpentine) drive belt, which powers multiple engine-driven components such as the alternator, air conditioning compressor, and other auxiliary systems. By applying consistent force to the belt, the tensioner reduces slack, prevents belt slip, and supports smooth belt operation under varying engine loads and temperatures.

Application:
Accessory drive belt tensioner assembly - installed in the front engine accessory drive system to control belt tension and alignment.
Function:
• Applies and regulates tension to the accessory drive belt
• Maintains proper belt alignment over pulleys
• Reduces belt chatter and premature wear
• Helps ensure reliable operation of belt-driven accessories
A worn or weak belt tensioner can lead to belt slip, increased noise (squeal or chirp), uneven belt wear, and reduced accessory performance. Replacing a failing tensioner restores proper tension control and helps prolong the life of the belt and pulleys - improving reliability and reducing the risk of accessory drive failures.
Replace the tensioner if you notice:
• Squealing or chirping from the belt area
• Visible belt wear or fraying
• Belt slipping under load
• Rough or noisy pulley bearing movement
• During routine accessory belt or tensioner service intervals
