Detailed Description

Roadmax 5K490AP is a serpentine belt engineered for accessory drive systems that power components such as the alternator, power steering pump, and, on select applications, the water pump. Its EPDM belt material is paired with polyester cord to help maintain belt shape and consistent rib engagement under normal engine bay conditions. This makes it a practical replacement choice for vehicles that require a 5-rib, K-profile belt with a 48.97-inch effective length.

This part cross-references Gates K050490 and Dayco 5050490 for the same application. It is listed for fitment on 1997-1999 Mitsubishi 3000GT, 1990-1998 Hyundai Sonata, 1991-1996 Dodge Stealth, 1994-1996 Mitsubishi Diamante, 1993 Hyundai Elantra, 1992-1993 Mitsubishi Diamante, 1989-1990 Mitsubishi Sigma, and 1988 Mitsubishi Galant. Search terms such as Mitsubishi 3000GT serpentine belt 5K490AP, Hyundai Sonata accessory drive belt, and Dodge Stealth alternator and power steering belt align with this application data.

What This Belt Helps Address

• Squealing or chirping from a worn accessory drive belt
• Cracking, glazing, or rib wear on the existing serpentine belt
• Loss of belt grip affecting alternator or power steering operation
• Incorrect belt length or rib count during replacement service
• Routine maintenance on listed Mitsubishi, Hyundai, and Dodge models

Installation Notes and Tips

Verify the belt routing and compare the old belt’s rib count, width, and length before installation. Confirm the vehicle position listed for your application, since some fitments are for alternator and power steering only while others also include water pump drive service. Inspect pulleys, tensioners, and idlers for wear before installing the new belt, and make sure all pulley grooves are clean and aligned.

For fitment-focused searches, this belt is listed for 1997-1999 Mitsubishi 3000GT, 1990-1998 Hyundai Sonata, and 1991-1996 Dodge Stealth in the specified accessory drive positions. The 5K490AP part number should be matched to the vehicle’s original belt specifications before service.

Quality Assurance

Roadmax’s standard V-ribbed belt line is aimed at value-focused replacement service while still using EPDM and reinforced cord construction for everyday accessory drive demands. Confirm all dimensions and fitment details against the vehicle application before installation.
