Goodyear Serpentine Belt 7-Rib 56.5" (1070565) EPDM Durability, OE Fit

Goodyear 1070565 is a 7-rib, 56.5-inch multi V serpentine belt engineered to restore accessory drive efficiency with long-lasting EPDM construction and OE-level fit.

When an aging belt causes squeal, slippage, or reduced accessory performance, replacing it with a properly sized, durable belt matters. The Goodyear 1070565 (alternate part 7PK1435) is made from EPDM rubber and balanced twist polyester cord to resist heat, ozone, and weathering. It’s designed to meet or exceed original equipment standards and works across alternators, water pumps, AC compressors, and power steering systems.

How will this belt affect drivetrain noise and vibration?

The Goodyear multi V design reduces vibration transfer and minimizes belt chirp compared with worn or generic belts. Its material formulation and cord reinforcement stabilize tracking and tension, producing a quieter running accessory drive under most operating conditions.

• 7-rib profile for even load distribution
• EPDM compound reduces cracking and noise over time
• Balanced twist polyester cord for stable tension and less vibration

Will this belt fit my vehicle and which components does it drive?

This particular belt fits a range of vehicles when the required belt length and rib count match: 56.5 inches (1435 mm) and 7 ribs. It’s suitable for alternators, water pumps, AC compressors and power steering pumps when those components use a single serpentine drive belt.

• Length: 56.5 in / 1435 mm (7PK1435)
• Compatible models include certain Acura, Honda, and BMW Z8 years—always verify fitment
• Designed for common accessory drives: alternator, AC, power steering, water pump

What materials and construction give this belt longer life?

Durability comes from Goodyear’s EPDM rubber compound and a balanced twist polyester cord core. EPDM resists heat, ozone, and weathering far better than older neoprene formulas, while the cord maintains tensile strength and reduces elongation under load.

• EPDM rubber for heat and ozone resistance
• Balanced twist polyester cord for tensile stability
• Multi V rib geometry for uniform wear

How should I check or replace this belt to avoid future issues?

Inspect the belt regularly for cracks, glazing, fraying, or rib separation; replace at the first signs of wear or if the belt has exceeded the manufacturer’s recommended service interval. Correct routing and appropriate tension (tensioner condition) are critical to ensure long life and quiet operation.

• Look for visible cracking, rib wear, and glazing
• Confirm correct routing and 7-rib alignment on pulleys
• Replace tensioner or idler pulleys if noisy or worn

Who this belt is for: Owners or mechanics who need a direct-fit, long-lasting serpentine replacement in a 56.5" length and 7-rib profile. It’s aimed at drivers of compatible Acura, Honda, and BMW Z8 models (check vehicle fitment) who want an OE-grade aftermarket belt that balances quiet operation, durability, and reliable accessory drive performance.
