The Contitech 642K6MK is a Multi-V serpentine belt for accessory drive applications across a wide range of Ford, Chevrolet, GMC, Cadillac, Buick, Pontiac, and Ford truck platforms. It is listed for accessory drive, alternator, air conditioning, and water pump routing depending on the vehicle application.

Key Features

  • Multi-V belt construction for accessory drive system routing.
  • Application-specific fitment for confirmed vehicle configurations.

Detailed Description

This serpentine belt is cataloged under Contitech’s Multi-V line and is specified for multiple accessory drive configurations. Fitment includes 2016-2024 Ford F-150, 2021-2022 Ford Lobo, 2016-2018 Ford Lobo, 2017-2019 Chevrolet Cruze, 2018-2019 Chevrolet Equinox, 2018-2019 GMC Terrain, and several 1990s GM passenger car applications such as Chevrolet Camaro, Pontiac Firebird, Buick Roadmaster, Cadillac Fleetwood, and Chevrolet Caprice. The 642K6MK part number should be matched to the exact engine and accessory routing shown in the fitment data.

Contitech Multi-V belts are identified by their multi-rib design, which is used to transfer drive power across engine accessories with the correct routing profile for the application. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Is Used For

  • Replacing a worn or cracked accessory drive belt.
  • Restoring proper alternator drive operation.
  • Restoring belt drive for air conditioning systems.
  • Restoring belt drive for water pump applications where listed.
  • Addressing belt noise, slippage, or routing wear.

Installation Notes and Tips

Verify the exact year, make, model, and accessory routing before ordering. Match the belt to the listed position and notes, including Multi-V, W/AC, Exc HD Cooling, or factory-installed AC where shown. Inspect pulleys, tensioners, and idlers for wear before installing the new belt, and confirm the routing path matches the vehicle configuration.
