Works well. Solidly built.

Works great as a factory replacement. It's much heavier than the stock (plastic) pulley, so it will not do anything to help performance. Not that you would buy this for performance reasons.

Good fit but different material than OEM

It a good fit and will suit my 200k mile WRX fine, but don't let "meets or exceeds OEM specs" fool you. The Subaru OEM part is made from light weight composite, while the Dayco part is a heavy chunk of stamped steel. Heavier means more rotational inertia and therefore less power and worse fuel economy. We're not talking a huge difference here, but if my car wasn't this old I would have sprung for the OEM part.

One thing I will say is the center of this pulley is slightly different pay attention to how close it will be to the timing belt cover or the other belt when you install.

      Was changing out Alternator and A/C pulley belts when I noticed the A/C idler pulley was bad. Phoned up my local Advanced Auto parts and had it in my hands within minutes and was able to complete the job quickly. Very convenient and a great price to boot! I Highly recommend ADVANCE AUTO PARTS for all your automotive needs.

        Installed on a 1997 Honda Civiv LX. Laid down side by side with the OEM pulley, this pulley was slightly taller and thus rubbed against the tension adjusting bracket after install. I unistalled it and placed a thin washer onto the pulley bolt before re-installing. Problem solved. Definitely a much quieter vechicle now.

          Comments about CARQUEST by Dayco Idler Pulley:

          The bearing is where the problems with "cheap" (or low quality in this case, as OEM other places is about $5) pulleys comes in. Mine has since eaten it's own bearing and is now rubbing against the bracket, badly. The stock one lasted 140K, this one hasn't even lasted 20K.

            Comments about CARQUEST by Dayco Idler Pulley:

            This pulley is doing the job so far. The bearing seems to be machined pressed so i believe there is no worry about it coming out which was my first impression. The original equipment manufacturer (oem) part was made of course different to where the bearing was able to come out of the pulley completely while having a lip on one side of the pulley and a dust cover on the other to keep it in place while installed.

            Pulley is heavy duty compared to Subaru's OEM pulley which is junk. Advance Auto should also have the tensioner bracket on hand that disintegrates along with the OEM pulley. That part has to be bought separate from Subaru.

                A:

                The pulley in question attaches to the motor of the vehicle. I recommend refering to a Haynes repair manual to see how to replace the pulley step by step. These Haynes repair manuals can be found at your local Advance Auto Parts store.
