Dayco idler/tensioner pulleys are built with smoother surfaces and tighter dimensional tolerances, which translates to less vibration and longer belt life. In addition to stamped, forged steel and powdered metal pulleys, Dayco also designs ultra-strong plastic pulleys with specially formulated glass-filled polymers that resist wear and tear. Premium lubricated ball bearings and double high temperature seals ensure peak bearing performance, the most critical element of a pulley's service life.

Price in store was higher than on-line.
Used the original dust cover and no issues to date.Just purchased & self-installed 6/4/10 in less than 15 minutes. Be sure to properly align pin in engine block before tightening. This was improperly installed after an engine replacement and is what caused the original bearing to fail.
Most Liked Negative Review
Cheap but works
Quality doesn't appear to be best compared to some of the OEM AcDelco pulleys. The Dayco pulley I just bought shows an obvious seem in the plastic, even on the ribs of the pulley. The actual bearing is labeled NTN & made in Canada. Ironically, the same tensioner pulley I'm replacing had NTN bearings.
After comparing both, the Duralast brand at Auto Zone is exactly the same as this Dayco Pulley, just repackaged and slightly cheaper. This makes me wonder what the real difference is in cheap parts brands anymore.
If not needed in a hurry I would have just bought the OEM AcDelco pulley from rockauto for about the same price and a piece of mind.

Hi Patricia, I'm glad to help you! We can only look up by the vehicle. Since you didn't mention the specific vehicle, it's hard to tell for sure. To give you the correct information I would need the year, make, model and engine size of the vehicle.
Is this the pulley for the top where power steering pump would be

Hi Nick, I'm glad to help you! This CARQUEST by Dayco Idler Pulley (Part # 89015) has an outside diameter of 70mm, width of 28.3mm and the bearing inside diameter is 17mm.
Would this pulley fit a 2007 dodge Dakota? (Alternator pulley) v6.
