After returning to Advance Auto to get the right part number tensioner (89230 vice 89252, online catalog problem), I installed it and ran the engine. It seemed to work OK. However, during a trip, my wife complained about a "rattle". When she returned, I heard a "clicking" noise which I noticed corresponding to tensioner movement. The noise has gone away, but after a conversation with a Dayco tech, I may end up having to replace it if the noise returns.

      Comments about CARQUEST by Dayco Automatic Belt Tensioner:

      this product was great easy to install and a direct fit from the worn out factory part. it does what it is supposed to do and keep the correct tension/deflecting rate on the belt. make sure when you replace this part that you put a little bit of thread lock on the bolt to help keep the vibrations from ever backing or out or loosen the bolt you don't need a lot

        Almost Perfect, '02 Explorer SOHC 4L V6

        Comments about CARQUEST by Dayco Automatic Belt Tensioner:

        This tensioner seems to work well now that it's installed in my 2002 Explorer - holds the belt right where it should be and seems to keep it plenty tight. Smooth and quiet operation. The only issue: the "body" of the tensioner is not quite as "thick" as the OEM. The belt pulley rides in exactly the same place, so function is not an issue, but the dust cover that was on the OEM unit added some thickness. The result: you can't use the original mounting bolt to install the tensioner - it is too long and will bottom out before this new, skinnier tensioner is tight against the mounting surface. The answer: Go to hardward store and buy a new bolt - I think it was M10 x 60-mm. Then you're good to go and no problems.

        • Q:

          When installing this Dayco belt tensioner, do I need to use a torque wrench? If not how is it bolted to the engine? Also, do bolts come with the tensioner?

            A:

            I recommend purchasing a Haynes repair manual specifically for your vehicle. This should be able to assist you further into detail on how to repair or replace specific parts. Bolts are not included with the tensioner.
