Had to stop the loud screeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeccccccccccccccccccccccccccccccccccccccccccccccccccccccccchhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhiiiiiiiiiiiinnnnnnnnnnnnnnnnnnnnnnnnnnggggggggggggggg noise due to the bearing in this part wearing out i guess. It is so annoying and i could not take it anymore. I installed this part in about 15 minutes and also replaced the serpentine belt that had appeared to have not been changed in the past 10 years haha. All is well now.

expected longer life

If you need one of these go with "Gates" They specialize in them as well as serpentine belts. You pay a little more, but you get what you pay for

  • Q:

    I have used two of these (thought first was defective) with two of the dayco poly rib belts, and the belts are stretching out to full tensioner extension within a few days. Then squeaks upon startup. What is the problem? The belts are the right size, having almost all of the tension left on the tensioner when installed. Both times the belt and tensioner were new. Vehicle has new alt, a/c compressor, water pump, and idler pulley as well. 98 chevy blazer.

  • Q:

    first, can a bad tensioner pulley make the engine preform like it has an ignition problem? such as needing a tune up. Secondly, is the tensioner pulley supposed to move up and down when the engine is running
    Asked on 8/5/2012 by pappy from pasadena Md.

    • CUSTOMER CARE

      A:

      The belt tensioner is a crucial part of any engine. Its functions include tightening the engine belt and transferring power through pulleys from the serpentine belt to the alternator. It is responsible for generating the correct amounts of tension to allow the engine to run and drive its components. Belt tensioners lose their strength and efficiency over time, which can lead to an engine failure if the belts aren't replaced. It's helpful to know the signs that the tensioner is worn or needs replacement. 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. 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 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. 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 visit your nearest Advance Auto store or call us directly at 1-877-ADVANCE (238-2623) and one of our representatives there would be more than happy to assist you.

  • Q:

    Can a bad belt tensioner drain your battery? When I drive it makes a noise and my battery goes dead. I have a new alternator and a new battery. My amp guage shows only 10 amps instead of 14. Its not holding a charge. My truck has 190,000 miles on it. Could it be the problem?

      Yes the tensioner comes with the pulley.

    • A:

      Yes it does come with the pulley wheel & bearing. Buddaman there description of Light duty pertains to Heavy Equipment applications where the engine is spinning at a constant Hi-RPM. This product will perform just fine in our highway vehicles.

      A:

      Yes, the tensioner comes with a pulley wheel. However there is another idler pulley on the 5.7 that is sold separately.I do not know if a heavy duty model is available, but this is the stock replacement part.
