This pulley matches thr original Chrysler part exactly, even the same brand of bearing. The only issue with it is that the Advance website has a horrible description. This idler is the one that attaches to the tensioner arm. The other idler is also called idler, but it is the one that is attached to the stationary bracket. I had to use the Dayco website to figure out which was which.

I bought this part for a 2003 Dodge Grand Caravan, 3.3L Flex-Fuel engine. This is not an idler pulley! It is narrower, smaller in diameter, and does not have the rounded front edge essential for installing the serpentine belt.
I typed "idler" into the search block and accepted the suggestion "idler/tensioner pulley". This part and Dayco part 89098 both show up. 89098 is correct, this is not, though they are both labeled "idler/tensioner pulley". This is a direct replacement for the tensioner pulley if you decide to replace the pulley only, not the whole tensioner.
The search engine for this site needs some work. If I accept the suggested topic "idler pulley" a Dorman part 419-610 comes up. This also appears to be the correct part.

    Comments about CARQUEST by Dayco Idler Pulley:

    The product appears to be a good match for the original, but because there was so little left of our original idler - the only thing I knew for sure is that the inner bearing race diameter was a match. The original bearing completely failed, and the original plastic pulley completely melted around the outer bearing race until the serpentine belt lost tension. The unfortunate part of this replacement is that it does not include the inner bushing (which was lost in the failure of the original) nor the bolt/washer/spacer. If I had the original bushing, I could assemble everything and all would be well. So, in brief, the bushing is a round spacer that fills the gap between the bolt which attaches the idler to the block, and the inner bearing race. The inner bearing race is much larger diameter than the diameter of the bolt, so without the bushing, there is no way to center the bolt in the race, and accurately attach everything.

            Part fits perfectly and seems to function properly. I wish it was made of steel, but it looks like a lot of manufacturers (even the OEM parts) are going with these plastic pulleys. They do seem to hold up OK. The purchase experience with Advance Auto Parts was great.

            Doesn't actually fit 2005 Corolla

            Comments about CARQUEST by Dayco Idler Pulley:

            Pulley and bearing diameters match up with the original pulley from a 2005 Corolla, but the bearing width is about 1mm narrower than the OEM part. Unfortunately, that moves the pulley over enough that it interferes with the tensioner assembly and won't rotate.

              Are the stationary pulley and the tension pulley one of the same part number. What part numbers do I need for both applications.

                A:

                I'm glad to assist, Dave! The idler and tensioner pulley on your 2006 Dodge Grand Caravan SXT 3.8L V6 are not the same size. Dayco Part No. 89144 is the correct pulley for your tensioner. Or you may purchase a tensioner assembly as Dayco Part No. 89280. Dayco Part No. 89007 is the correct idler pulley for your vehicle.

                A:

                You would need the following tools while replacing the pulley in your 2001 Volkswagen Jetta GLS: 16 mm box wrench, 13 mm socket (may need regular and deep) extension, 6 mm hex bit (the shorter the better), torque wrench, ratchet, flathead screwdriver, pliers. Remove the serpentine belt by placing the 16 mm box wrench onto the "nut" on the tensioner and pushing back towards the firewall to relieve the tension and slip the belt off the pulleys. You can use a second wrench on the end of the first for extra leverage. Pop the "hat" off the idler pulley with a screwdriver and loosen the bolt with a 6 mm hex wrench. If you use a socketed bit, use the shortest one you have since clearance is tight. Remove the 3x 13 mm bolts holding the tensioner (arrows in photo). It may help to remove the upper hose leading to the EGR to give you some room. For any further assistance please feel free to call us at: 1-877-238-2623 or visit the nearest Advance Auto store and one of our representatives will gladly assist you with any questions or concerns you may have.
