Product Details

Gates Premium OE Micro-V belts are engineered to match OE size, construction, and materials so the belt can operate with the same general fit and routing expected from the factory design. The K040350 is a K-section, 4-rib serpentine belt used across accessory drive, alternator, water pump, air conditioning, and power steering applications depending on the vehicle. This part cross-references Continental 4K890 and Dayco 5040350 for the same application. For buyers searching for a Toyota Hilux serpentine belt, Hyundai Elantra accessory drive belt, or Kia Sportage alternator belt, this part number is a direct OE-style replacement to verify against the listed fitment.

Common Problems This Belt Can Address

• Squealing or chirping from a worn accessory drive belt
• Cracking, glazing, or rib wear on the existing belt
• Loss of proper drive to the alternator, water pump, A/C compressor, or power steering pump
• Belt length or profile mismatch after a previous replacement
• Reduced belt tracking caused by age-related stretch or material breakdown
