Special belt constructions eliminate belt noise, reduce tension loss and solve problem drive applications.
Last 50%-60% longer than value line belts.
Extra heavy-duty construction resists cracking and wear.
Precision ground to assure optimum belt-to-pulley fit.
Special formation process for precise dimensional control.
Reinforced with stretch-resistant, thermally active polyester tensile members.

You should check the serpentine belt at every oil change for cracks and chunks missing out of it and general wear. If you see these, it is time to replace the belt.

While the belt is off for replacement, give the belt tensioner pulley a spin and listen for bearing noises. A squealing belt can be a sign that the belt tensioner is failing and causing belt misalignment.
