Detailed Description

Contitech 845K6MK is a serpentine belt built for Multi-V accessory drive systems. The fitment list includes Dodge Challenger and Dodge Charger alternator applications, BMW X5 and 535d accessory drive applications, and Jeep Wrangler and Jeep TJ accessory drive applications, along with older Mercedes-Benz, Ford Mustang, Ford LTD, and Mercury Capri listings. If you are replacing a worn belt on a BMW X5, Jeep Wrangler, or Ford Mustang, this part number helps narrow the search to the correct drive configuration.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

  • Squealing or chirping from a worn serpentine belt.
  • Cracking, glazing, or visible belt wear.
  • Charging issues caused by belt slip at the alternator.
  • Accessory drive noise from an aging belt.
  • Loss of proper drive to engine accessories.

Installation Notes and Tips

Verify the exact engine and accessory-drive configuration before ordering, especially on BMW Dynamic Drive, Jeep 7-point drive, and Mercedes-Benz or Ford applications with exclusions noted in fitment. Match the belt routing and confirm the listed position and notes against the vehicle already on the car. Use the part number 845K6MK to confirm catalog accuracy during replacement.
