Detailed Description

Dayco 17740 is an accessory drive belt for vehicles that use a 74-inch belt length and a 36-degree belt angle. The top-cog construction helps the belt conform to pulley systems in accessory drive applications, while the synthetic rubber compound supports consistent performance in everyday engine bay conditions. This belt is a practical replacement choice for heavy-duty and on-road applications where correct belt dimensions matter, including select Freightliner, Mack, and Navistar setups.

What It Helps Address

  • Squealing or chirping from a worn accessory drive belt
  • Cracking, glazing, or visible wear on the belt surface
  • Loss of accessory drive performance from belt stretch or mismatch
  • Incorrect belt length or profile during replacement service
  • Temperature-related belt performance issues in demanding engine compartments

Installation Notes and Tips

Verify belt length, top width, and pulley angle before installation. Confirm routing against the vehicle’s belt diagram and inspect pulleys, tensioners, and idlers for wear before installing Dayco 17740. For fitment-based searches, this belt is commonly referenced for Freightliner, Mack, and Navistar applications; confirm the exact engine and accessory drive configuration before ordering. Fits 2006-2011 Honda Civic, front right is not applicable here because no passenger-vehicle fitment is listed for this part.
