How to Replace an Idler Pulley on a 1993 Dodge Dakota Sport

92

Dodge uses an idler pulley to create consistent tension on the serpentine belt in the 1993 Dodge Dakota Sport. As the belt stretches out, a spring on the idler pulley forces the belt tighter. Over time, the bearing inside the idler pulley wears out and eventually, it could seize up. This causes the serpentine belt to slip on the idler pulley and start to squeal. It could cause the belt to break as well. If the idler in your Dakota wears out, purchase a new one from a Dodge dealership and install it on your Dakota.

Tools Used: Tools, 3/8-inch ratchet driver, Socket set

Replace Idler Pulley

Locate the idler pulley toward the bottom of the engine. The pulley has a square hole in the face of it. Place the 3/8-inch ratchet driver into the square hole on the face of the idler pulley and pull up on the handle. Pull the belt off the pulley. Do not pull the belt off any other pulley

Remove the two bolts that secure the idler pulley bracket onto the engine block using a socket and ratchet. Secure the new idler pulley bracket to the engine block using the original bolts, a socket and a ratchet. Put the 3/8-inch ratchet driver into the square hole on the new pulley and pull up on the handle. Slide the belt over the pulley and remove the ratchet from the pulley.
