This belt tensioner pulley is NOT a genuine OEM part. Vehicle makes and their associated vehicle models and part numbers are used in this listing only to identify the vehicles this belt tensioner fits.

Review: This item arrived on time, great quality for a critical part that gets ignored until it explodes. Replace this item if you are over 100k and do not know when it was replaced. I have been in trucks when this part gives up the ghost, and it is a bummer when the part is inexpensive and so easy to replace. I would recommend that you purchase the GOOACC GRC-30 plastic rivet clips kit that includes the tool to remove the 4 clips on the Radiator shroud. The tool in the rivet tool kit makes is sooo easy to remove the clips on the side of the Radiator, well worth the inexpensive cost. The only bolts are 2 on the top of the radiator. Once the shroud is out of the way, it is easy to replace any of the components related to the serpentine belt.
Review: Easy replacement, it looks like it will last a long time.
