Key Features

• 0.47-inch belt top width for proper pulley contact and tracking
• 32.10-inch belt length for specified accessory drive applications
• EPDM compound for high heat and abrasion resistance
• High-strength fiber reinforcement helps control elongation
• Precision sidewalls and top width meet or exceed SAE J636 standards
• Built for traction, quiet operation, and long service life

Product Details

Continental Automotive V-Belt part number 15321 is engineered for accessory drive systems where accurate belt dimensions matter. The EPDM construction resists heat and wear, while the reinforced design helps maintain belt stability under load. This makes the 15321 a practical replacement for vehicles that use a traditional V-belt layout, including applications on BMW 318i and 318is power steering systems, as well as Ford, Isuzu, Mazda, and Chevrolet accessory drives. This part cross-references Dayco 15315 for the same application.

Compatible With select applications such as Fits 1991-1993 BMW 318i, Power Steering; Fits 1991-1993 BMW 318is, Power Steering; Fits 1986-1991 Mazda RX-7, Alternator; Fits 1991-1997 Isuzu Rodeo, Air Pump; and Fits 1983-1987 Nissan Sentra, Alternator, w/o AC. It also appears in accessory drive setups for Ford E-350 Econoline, Chevrolet Cavalier, and Volkswagen Quantum models. If you are replacing a worn Continental 15321 belt on a BMW M3 or Mazda RX-7, verify pulley routing and belt length before installation.

Common Uses

• Restoring alternator drive performance when the old belt is cracked, glazed, or stretched
• Correcting squeal caused by belt slip on power steering or air pump drives
• Replacing a belt that no longer maintains proper tension
• Addressing accessory charging or cooling issues tied to belt wear
• Replacing a worn V-belt on select BMW, Ford, Isuzu, Mazda, and Chevrolet applications

Installation Notes

Confirm the belt top width, length, and pulley routing against the vehicle’s accessory drive layout before installation. Inspect pulleys, tensioners, and accessory brackets for wear or misalignment, since these conditions can shorten belt life. After installation, run the engine and verify tracking, tension, and quiet operation across the full accessory drive path.

Quality Assurance

Continental uses EPDM compounds and fiber reinforcement to support heat resistance, abrasion resistance, and controlled elongation. The belt’s dimensions and sidewall profile are made to meet or exceed SAE J636 standards for consistent fit and performance.
