A-Premium Serpentine Belt 6-Rib 39.69 in — Direct-Fit EPDM for Hyundai & Kia Alternator

This heavy-duty accessory belt is engineered with EPDM rubber and polyester cords to match OE dimensions and deliver long-term resistance to heat, oils, and environmental wear. It fits alternator-driven configurations on many Hyundai Sonata, Santa Fe, Tucson and several Kia Optima, Sorento and Sportage model years. The belt's measured 39.69-inch effective length and six ribs provide consistent contact with pulleys for stable tension, quieter operation and reduced vibration compared with worn or mismatched belts.

Which vehicles and engine positions does this belt fit?

This A-Premium belt is targeted for gasoline-powered Hyundai and Kia four-cylinder models where the alternator uses a 6-rib belt. It is listed for Sonata, Santa Fe, Santa Fe Sport, Tucson, Optima, Sorento and Sportage across the model years shown in the fitment notes. Always verify your OEM reference number or measure the old belt before purchase.

• Hyundai Sonata: 2015–2019 L4 2.0L / 2.4L (alternator position)
• Hyundai Santa Fe & Santa Fe Sport: 2016–2020 L4 2.0L / 2.4L (alternator)
• Hyundai Tucson: 2018–2021 L4 2.4L (alternator)
• Kia Optima, Sorento, Sportage: select 2016–2022 L4 2.0L / 2.4L alternator fits

What are the belt's key measurements and materials?

Dimensions and construction mirror OE guidance so the belt maintains correct routing and tension. The effective length and outside circumference ensure a proper wrap on accessory pulleys without altering drive geometry. Polyester cords keep tensile strength while EPDM compound resists aging factors common under the hood.

• Effective length: 39.69 in; outside circumference: 40.25 in
• Rib count: 6; top width: 0.807 in; cross section: K
• Materials: EPDM rubber body with polyester tensile cords
• Reference IDs: K060396A, 252122GGA1, 5750T2, 7700745397, 96155010

How does this belt perform compared to a worn OEM belt?

The EPDM compound and precision molding aim to reduce cracking, glazing and early deterioration common with older rubber belts. Proper fitment maintains accessory alignment, which lowers noise and vibration. However, longevity depends on installation quality and the condition of pulleys and the tensioner.

• Engineered to resist oils, heat and environmental contaminants
• Precision dimensions for improved tension control and quieter running
• Helps prevent slippage when installed with good tensioner and pulley condition

What should you check before and after installing this belt?

Replacing a serpentine belt is an opportunity to inspect the drive system. Tensioner loss, bearing play in pulleys, or misalignment can shorten a new belt's life. Confirm routing, torque specs, and tensioner functionality to get the expected service life from the replacement belt.

• Inspect tensioner spring and pulley bearings for play or noise
• Verify pulley alignment and clean mating surfaces if needed
• Follow approved routing diagrams and tension settings during installation

This A-Premium serpentine belt comes backed by a one-year unlimited-mileage guarantee and is sold as a direct replacement for the reference numbers listed. It is manufactured for gasoline engines and intended for use where listed, but buyers should always confirm compatibility with their vehicle's VIN or OEM part lookup.

Who is this for? If you maintain a compatible Hyundai or Kia with a worn or noisy 6-rib alternator belt and want an OE-dimension replacement built from EPDM and polyester cord reinforcement, this belt is made for technicians, DIY enthusiasts and fleet managers seeking reliable, cost-effective accessory drive restoration.
