        Went to the store and ended up with a new trainee, the person who was working with him walked off and I had to call him back. Gave them all of the information and they came back with this one. It didn't look anything like the one I took off but, they assured it was correct (not). Put it on and it broke immediately, This is when I went online and discovered this was for light duty. mine is a 3/4 ton sub. Looking for the manager when I go back and then the regional manager!

          Replacement part that fits like the original. Looks and is shaped a little different, but that it because the original used a round wire type spring, this uses a flat bar spring, which Dayco claims is better. Time will tell. My original spring was not broken, there was some wear on the pivot point.

              Comments about CARQUEST by Dayco Belt Tensioner:

              My old pulley was making a rattling noise due to age. I bought the first Dayco which I put on with ease but when I ran my truck for 3 weeks a persistent high pitch squeak that followed my rpms continued to persist. I took it off and found that the bolt was stripping the aluminum thread in the piece. I replaced a second time and guess what happened, same exact thing.

                    Hi Mike! 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.

                  what is the nylon bushing for and do I need to install it? Thanks

                  • A:

                    The bolt is too large to fit the nylon bushing. I assumed it was for vehicles that had a smaller bolt which would then need the bushing to fit the Belt Tensioner.

                    A:

                    Hi Rickster, good question! You would need to install this bushing as the patented nylon pivot bushing on this belt tensioner keeps internal components in constant contact to maintain proper tensioner alignment.

                    A:

                    Signs of a bad belt tensioner: Battery Light: The car battery light will light up when the belt tensioner is failing. The battery will begin to run down due to the fact that the belt is slowing down and slipping out of its compartment. In addition, the alternator will no longer turn fast enough to power the battery. Looseness: One of the main signs that a belt tensioner needs replacement is the looseness of the belt. Listen for a fluttering" noise while driving or while the car is idling. This indicates the tensioner is too loose. Other noises such as squealing or whirling from the front of the engine mean the spring inside the tensioner is weakening. In this case, the belt tensioner needs to be replaced. Rust and Debris: Rust or corrosion can build up around the tensioner, as well as dirt and mud. Rust prevents the tensioner from spinning freely, which can cause further damage to the engine. Corrosion can occur in areas with a colder climate, and where roads are heavily salted during winter. Rust also tends to distribute into other parts of the engine, including the alternator. Pulley Damage: Any damage to the automatic tensioner pulley can cause damage to the belt tensioner due to the vibrations caused by the pulley. Physical damage to the pulley is an indication of extreme tension or physical interference. For any further assistance, please feel free to call us at: 1-877-238-2623 or visit the nearest Advance Auto Parts store and one of our Parts Pros will gladly assist you with any questions or concerns you may have.
