Gates Premium OE Micro-V Belt K050490

The Gates Premium OE Micro-V Belt K050490 is a serpentine belt built for accessory drive systems that need accurate OE-style fit and consistent operation. It uses EPDM belt material, a polyester cord, and a 5-rib, K-section design to match the dimensions and construction expected in factory applications.

Compatible With Mitsubishi 3000GT, Hyundai Sonata, Dodge Stealth, Mitsubishi Diamante, Hyundai Elantra, Mitsubishi Sigma, and Mitsubishi Galant applications that use an alternator and power steering drive, plus select air conditioning and water pump drive positions.

Product Details

Gates engineered this Micro-V belt to match OE size, construction, and materials for import and domestic vehicles. The K050490 uses a standard automotive V-ribbed profile with a K cross section and 5 ribs, making it suitable for accessory drive systems where belt tracking, grip, and dimensional accuracy matter. In applications such as the Mitsubishi 3000GT, Hyundai Sonata, and Dodge Stealth, the belt supports alternator and power steering drive functions, while other listed vehicles use it in air conditioning or water pump, alternator, and power steering positions.

Common Issues This Belt Can Address

• Squealing or chirping from a worn accessory drive belt
• Cracking, glazing, or rib wear on the existing serpentine belt
• Loss of proper belt tension or tracking due to age-related stretch
• Accessory drive noise affecting alternator or power steering operation
• Fitment problems caused by an incorrect belt length or rib count

Installation Notes and Tips

Verify the belt routing against the vehicle’s accessory drive diagram before installation. Confirm the required effective length, outside circumference, rib count, and section designation match the original belt specification. Inspect pulleys, tensioners, and idlers for wear before installing the new belt, since damaged components can shorten belt life and affect tracking.
