Gates K120911HD Serpentine Belt
This Gates serpentine belt is a heavy-duty replacement component for automotive engines. It fits vehicles requiring industry number K120911HD with an outside length of 91.75 inches and a top width of 1.65 inches. The belt is supplied new and features a green colour.
Replaces worn or cracked original belts
Install this belt when the factory drive belt shows signs of glazing, fraying, or excessive noise. The heavy-duty construction is suited for demanding accessory drives. It is not intended for applications specifying a different industry number, length, or width.
Practical limits of V-belt drive systems
V-belt drives transmit power through friction and require correct tension to prevent slip. Over-tensioning shortens bearing life in driven accessories. Belt stretch over time necessitates periodic inspection and re-tensioning. Extreme temperatures and oil contamination accelerate wear.

Questions about this item
What outside length and top width must the pulleys accommodate for this K120911HD belt?
The belt measures 91.75 inches in outside length and 1.65 inches in top width, so the pulley groove and centre distance must match those dimensions.
How is the Gates K120911HD serpentine belt installed and what step is often missed?
Route the belt around all driven accessories following the engine’s routing diagram, tension it with the automatic tensioner, then verify the ribs seat fully in every pulley groove — the seating check is the step most often skipped.
When should this heavy-duty V-belt be inspected or replaced?
Inspect for cracking, glazing or rib wear at every oil change; replace immediately if cracks reach the cord, ribs are missing, or the belt has been in service beyond the vehicle manufacturer’s recommended interval.
