X AUTOHAUX Drive Belt Tensioner Pulley Assembly replaces worn tensioners to restore proper belt tension and reduce accessory belt noise.

What should I check before purchasing and installing?

Confirm your vehicle’s make, model, year, and engine size to avoid fitment issues. Also inspect belt routing and adjacent pulleys—sometimes multiple components wear together and may need replacement at the same time.

• Verify engine displacement and production years listed in the fitment section
• Measure or compare the old tensioner against this unit for mounting and bolt pattern
• Consider replacing the accessory belt if it shows cracks, glazing, or excessive wear
