About this part

Idler pulleys guide the serpentine belt around the accessories and keep it at the right wrap. A worn bearing makes a chirp or growl and can wobble enough to throw the belt. Dayco 89165 is a smooth faced idler, which runs on the back side of the serpentine belt. The catalog ties it to trucks with dual alternators, where the belt routing differs from single alternator trucks.

Fitment notes

89165 is listed for the 2005 Chevrolet Silverado 2500 HD with the 6.6L V8 and dual alternators. Single alternator trucks may use another pulley. Check your setup against the fitment table, or send your VIN.
