Gates K120870HD Serpentine Belt

This Gates K120870HD serpentine belt is a heavy-duty automotive V-belt designed for engine accessory drives. It suits technicians and vehicle owners replacing a worn belt on compatible applications. The green belt carries industry number K120870HD for identification.

Replaces worn or cracked OE belts

Install this belt when the original equipment belt shows cracking, glazing or tension loss that causes squeal or slip. The heavy-duty construction resists heat and abrasion better than standard duty belts, making the upgrade worthwhile on high-mileage or severe-service engines. California Proposition 65 warnings apply to this product.

V-belt drive limitations

The 1.65 in. top width and 87.63 in. outside length fix the pulley groove geometry and centre distance this belt can serve. It cannot be used on serpentine systems requiring a different rib profile or length. Correct tension and alignment are essential to prevent premature wear.
