Gates 2/9690PB Accessory Drive Belt - Fan and Alternator

Gates High Capacity Joined V-Belt 2/9690PB

The Gates 2/9690PB High Capacity Joined V-Belt is built for heavy-duty accessory drive systems that see high vibration and demanding belt-set operation. Its joined construction helps the belts run as a single unit for steadier tracking and more even load distribution.

For service work on vehicles that need a stable accessory drive belt, this Gates PowerBand design supports consistent pulley engagement and secure strand fit. It is a practical choice for applications where belt stability matters, including select Ford F-150 and Chevrolet Silverado accessory drive setups.

• Permanent tie band joins multiple V-belts into one unit
• Notched construction for improved flexibility
• EPDM belt material for durable accessory drive performance
• Polyester cord material for strength and dimensional stability
• HC50 section with 36-degree angle
• Top width per strand: 0.5 in. (13 mm)

• Outside circumference: 69.99 in. (1778 mm)

Product Details

Gates PowerBand belts are engineered for problematic, high-vibration accessory drive systems that require matched belt sets. The joined-band construction keeps the strands aligned so the belt set behaves as one piece, helping maintain stable operation across pulley grooves. The 2/9690PB part number is also referenced in service and interchange listings for related applications, including DENSO Auto Parts 5376.

This accessory drive belt is a fitment-focused replacement for vehicles that call for an HC50 joined V-belt profile. When servicing Ford F-150 or Chevrolet Silverado belt-drive systems, confirm the belt section, length, and pulley requirements against the original specification before installation.

What It Helps Address

• Belt flutter in high-vibration accessory drive systems
• Uneven load sharing between matched belt strands
• Tracking issues caused by separated or mismatched belts
• Noise from worn or unstable V-belt operation
• Loss of accessory drive consistency from aging belt material

Installation Notes and Tips

Inspect pulley grooves, tensioner condition, and alignment before installing the new belt. Verify the HC50 section, 69.11-inch effective length, and 36-degree angle match the original belt specification for the vehicle. After installation, recheck belt tracking and accessory drive operation during initial run-in.
