A-Premium Serpentine Belt 6-Rib 101.66 in — Direct-Fit EPDM for Hyundai & Kia

This A-Premium belt matches the specified effective length of 101.66 inches and a 6-rib K cross-section to restore proper accessory drive function—air conditioning, alternator, water pump and related pulleys—on listed vehicles. Constructed from EPDM rubber with polyester cords, the design emphasizes durability, heat resistance and reduced noise when installed with a correctly adjusted tensioner.

Which cars will this serpentine belt fit?

This belt fits many 2.4L four-cylinder Hyundai and Kia models from the mid-2000s to early 2010s, plus specified Mercedes-Benz V12 gas engines. Fitment varies by model year and accessory configuration (for example, air conditioning location and electronic power steering presence), so always cross-check part references and vehicle details before purchase.

• Hyundai Sonata 2006–2010 L4 2.4L
• Kia Optima 2006–2010 L4 2.4L; Rondo 2007–2011 L4 2.4L; Magentis 2007–2010 L4 2.4L

What are the belt's key specifications and materials?

The A-Premium belt is specified with an effective length of 101.66 inches and a 6-rib K profile. Manufactured from EPDM compound and reinforced with polyester cords, it provides a balance of flexibility and tensile strength to maintain correct pulley contact and tension.

• Effective Length: 101.66 in; Outside Circumference: 102.25 in
• Rib Quantity: 6; Top Width: 0.807 in; Cross Section: K
• Materials: EPDM rubber body with polyester cord reinforcement
• Reference numbers: K061016, 6PK2585, 6PK2580XS, plus OEM cross-refs

How does this belt improve reliability and noise control?

EPDM rubber resists cracking, oils and environmental contaminants better than older formulations, which helps preserve belt integrity under heat and load. Precision dimensions and cord reinforcement reduce slippage, vibration and belt noise when the tensioner and pulleys are in good condition.

• EPDM compound resists heat, ozone and oil exposure
• Polyester cords maintain tensile strength and alignment
• Accurate cross-section reduces belt flutter and squeal
• Recommended: inspect/replace tensioner and pulleys during service

How should I install and verify this replacement belt?

Installation is straightforward for mechanically skilled owners and shops: route the belt per the vehicle diagram, set tension with the factory tensioner, and confirm proper pulley tracking. Tool-free maneuvering is often possible with the designed fit, but verifying tensioner condition is important to prevent premature wear.

• Follow vehicle-specific belt routing diagram
• Use the factory tensioner; replace if worn or noisy
• Check alignment on all pulleys and accessories after installation
• Run engine briefly and re-check tension and noise

Who is this product for? Owners and mechanics seeking a direct aftermarket replacement for worn serpentine belts on the listed Hyundai, Kia and select Mercedes-Benz applications will find this A-Premium 6-rib belt appropriate. It is aimed at drivers who prioritize durability, OEM-equivalent fitment and quieter operation when the rest of the accessory drive system is in good condition. If your vehicle matches the listed fitment and uses a 6-rib K-profile belt, this part provides a cost-effective, one-year guaranteed option for restoring accessory-drive performance.
