Detailed Description

Dayco 89028 is an accessory drive belt idler pulley used in serpentine belt systems where the belt must be guided, tensioned, or routed around an accessory drive component. The polymer pulley body and 6-groove profile are matched to 6-rib serpentine belts, while the single bearing design supports smooth pulley rotation in the accessory drive belt system. This part number appears in applications for Chrysler Town & Country, Dodge Caravan, Dodge Grand Caravan, Plymouth Voyager, and related vehicles, including air conditioning bypass and grooved pulley positions. If you are servicing a Chrysler Town & Country, Dodge Caravan, or Plymouth Voyager with the listed configuration, Dayco 89028 is the catalog reference to verify against the original pulley.

This part cross-references ACDelco 38034 for the same application.

What It Is Used For

Replacing a worn or noisy serpentine belt idler pulley
Correcting belt tracking issues in grooved pulley applications
Restoring proper belt routing in air conditioning bypass setups
Addressing pulley wobble caused by bearing wear
Resolving squeal or chirp from accessory drive belt contact

Installation Notes and Tips

Verify the pulley groove count, belt width, and mounting position before installation. Confirm the vehicle’s configuration against the listed fitment, especially for models noted as without air conditioning or with air conditioning bypass. Inspect the serpentine belt, adjacent pulleys, and belt tensioner condition during service so the new idler pulley is installed into a clean, aligned belt path.
