Product Details

The Gates High Capacity V-Belt line is engineered for accessory drives that see frequent heat cycling and sustained load. This belt’s variable notched design helps it conform to pulleys more effectively as operating temperature changes, which supports consistent drive performance and quieter operation. The Gates 7665 is a direct-fit style accessory drive belt for the listed Dodge Monaco configurations and is also cross-referenced to Bosch 15665 and Dorman - HELP 13665 for the same application.

Use this belt when servicing the accessory drive system on a 1975-1976 Dodge Monaco, including alternator and air conditioning setups or alternator-only configurations with a Leece Neville alternator. The Gates 7665 is specified around the HC41 section and 67.3-inch outside circumference, making it important to verify pulley routing and belt length before installation.

Common Issues This Belt Can Address

• Squealing from a worn or glazed accessory drive belt
• Belt slippage under engine load or heat
• Cracking, fraying, or hardening of the existing V-belt
• Reduced accessory drive performance from incorrect belt length
• Noise from a belt that no longer tracks properly on the pulleys

Installation Notes

Confirm the belt routing, pulley alignment, and required outside circumference before installation. This belt is listed for 1975-1976 Dodge Monaco models with Leece Neville alternator applications, including alternator and air conditioning configurations and alternator-only configurations. Inspect pulleys and tensioning components for wear, then set belt tension to the vehicle manufacturer’s specification after installation.
