6. Note the orientation of the original pulley before removal.
7. Position the new tensioner pulley in the same orientation as the original.
8. Secure the new pulley using the mounting bolts, tightening them to the manufacturer's recommended torque specifications.
9. Return the tensioner mechanism to its neutral position using the wrench.
10. Reinstall the belt, ensuring it is correctly seated on all pulleys.
11. Apply proper tension according to your engine's service manual specifications.

How do I confirm this fits my engine?
First, check your engine model and year against the compatibility list above. Second, verify that your current part number matches one of the numbers in our cross-reference table, such as the primary OEM number 3582324.

Common signs of a worn or failing tension pulley include persistent squealing or grinding noises from the engine bay, a visibly wobbling or loose serpentine belt, or physical damage and excessive wear on the pulley surface.
