A-Premium Serpentine Belt 7-Rib 82.2 in — EPDM K-Section for Toyota/Lexus 3.5L V6, OE Fit

A-Premium Serpentine Belt 7-Rib 82.2 In is a direct-fit, EPDM 7-rib replacement belt engineered for Toyota Avalon, Camry, Sienna and Lexus 3.5L V6 models that require an 82.2-inch effective length.

This replacement drive belt is designed to restore reliable accessory drive performance for compatible 3.5L V6 Toyota and Lexus vehicles. Built from EPDM rubber with polyester cords and a K cross-section, the belt balances flexibility with tensile strength to help maintain proper tension, reduce slippage, and resist environmental wear. The product includes multiple OE reference numbers so you can confirm fitment before purchase.

How do I confirm this belt fits my car?

Match the belt’s effective length and rib count to your vehicle’s factory specification and compare OE reference numbers. This belt is intended for gasoline 3.5L V6 applications listed below; verify engine code and production year in your owner’s manual or parts diagram.

• Effective length: 82.2 inches; outside circumference: 82.75 inches
• Rib count: 7; cross-section designation: K
• Reference numbers: K070822, 7PK2090, 90916A2010, 99367C2090
• Compatible models: Toyota Avalon (2005–2012), Camry (2007–2011), Sienna (2007–2010); Lexus ES350 (2007–2012), RX350 (2007–2009) — gas only

What are the construction and materials, and why do they matter?

The belt uses EPDM rubber compounded for heat and chemical resistance paired with polyester cords for tensile strength. Those materials influence longevity, heat tolerance, and dimensional stability under load, which helps preserve accessory alignment and reduce belt noise.

• EPDM rubber resists cracking, oils, and contaminants
• Polyester cord provides consistent tensile strength and stretch resistance
• K-type 7-rib profile maintains contact with pulleys for secure power transfer
• Precise top width: 0.947 inches for correct pulley engagement

How does installation and maintenance work for this belt?

Installation typically follows standard serpentine-belt replacement procedures with a tensioner tool or tensioner release, depending on vehicle. Inspect or replace the belt tensioner and idler pulleys while installing to ensure correct tension and prevent premature wear.

• Tool-free features refer to ease of replacement when using proper tensioner tools
• Inspect tensioner and idler bearings for smooth operation before fitting
• Rotate engine by hand after installation to confirm alignment and clearance
• Follow factory torque and routing diagrams for safe, correct installation

What durability and warranty should I expect?

A-Premium designs this belt to withstand typical engine bay stresses—heat cycles, oils, and road contaminants—thanks to the EPDM compound and reinforced cords. The product is backed by a one-year unlimited-mileage guarantee covering manufacturing defects to provide added confidence.

• EPDM compound for improved resistance to cracking and environmental degradation
• Reduced vibration and noise through precision-engineered dimensions
• One-year unlimited-mileage guarantee against manufacturing defects
• Recommended: check tensioner condition to maximize service life

Who this is for: This serpentine belt is aimed at owners and technicians working on mid-2000s to early-2010s Toyota and Lexus 3.5L V6 vehicles who need an exact-dimension replacement. It suits DIY mechanics, independent repair shops, and fleet service teams seeking a cost-effective belt built from modern EPDM materials that match OE specifications. If you require an 82.2-inch effective length, seven-rib K-section belt with the referenced OE numbers, this A-Premium belt is a practical, warrantied choice to restore accessory drive function and reduce noise and slippage when fitted with a healthy tensioner and pulleys.
