A-Premium Stretch-Fit Serpentine Belt 3-Rib 30.35 in — EPDM K-Section for Hyundai & Kia 2.0L/2.4L

A-Premium's Stretch Fit 3-rib serpentine belt is a 30.35-inch EPDM drive belt designed to replace worn water pump and accessory belts on select Hyundai and Kia 4-cylinder models.

This high-durability replacement belt uses a stretch-fit design and polyester cords to deliver reliable routing for the water pump and, on some fitments, the air conditioning compressor. Engineered in K cross-section with a top width of 0.42 inches and an outside circumference of 30.88 inches, the belt balances a compact profile with long-wearing EPDM compound. It is supplied to match factory fitments for a range of 2.0L and 2.4L Hyundai and Kia engines, and it requires a 3mm zip tie for installation where indicated.

How is this belt different from standard wrap-around belts?

The A-Premium stretch-fit design is made to be installed by stretching the belt over pulleys rather than threading it through a tensioner. Because the EPDM material and polyester cords are engineered to contract into place, the belt self-tensions after installation and maintains consistent engagement under normal operating conditions.

• Stretch-fit style — no manual tensioner adjustment required after seating
• EPDM construction — enhanced temperature and corrosion resistance
• Polyester cord reinforcement — stable dimensional growth and load transfer
• Precise K cross-section: top width 0.42 in, outside circumference 30.88 in

What are the key specifications and installation notes I should know?
