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.

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

          It's a belt tensioner what do you expect, the real comments should be in one year. Then we'll know if if lasted or it's a normal pc from china that last about 6 mths.
          What really bugs me is how I stop at my local Parts Store the other day cause I had a engine light on, hey we don't do that anymore? I spend lot's of money buying parts from you guy's and you started this back in the garage deal for what so you could pull services from us? I know why your doing it but for us that spend money with your company you should over a special card for those that spend a certain amount each year to get special treatment like checking engine lights when needed. Whoever came up with this bright idea should fired, I wonder how much business you'll lose over this bad idea.
          Thanks,
          Not so happy Jerry

            Proper fit for older 2000 escalade with 5.7 liter engine, only slight gotcha is the mounting bolt that comes with the new one has a larger head than the factory so be ready to change wrenches if you do not reuse the factory mounting bolt other than that no realistic issues.

              With belt tensioner pulled all the way, still couldn't get the belt installed. Unbolted the alternator which gave enough slack to install. No slack on tensioner with the belt installed. After driving a few miles, there was about 1/4" slack. I had lots of noise before installing and the old tensioner was wobbling a small amount. The new tensioner has no wobble and the noise is gone. I thought I had a bearing going bad in the alternator or idler pulley. Replaced idler pulleys first which was needed. Even the pulley on the belt tensioner. Live and learn.

                Glad I replaced mine (did when I redid the radiator and water pump)... didn't have any symptoms but the original piece had stress cracks and the spring was weakened (~115k miles). Don't skimp... do it.

                • 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.

                  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

                    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.

                  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?
