Snap to replace and the sealed bearings is a plus for me. New part did not have a mounting nut with it, but the old one worked just fine. New problem is that I need to replace the other pulleys to match the "quietness" of this one :-)

product was in stock in and out in no time. got home and the assembly was keeping the coil pack from seating properly. had to space the coil pack for assembly to fit properly. when i put the oil dipstick back in i accidently hit the pully with the bolt bracket on the stick. left a straight scratch line on the pully across the teeth. not very durable at all. product fits everything except its just a touch over sized so plan on spacing your coil pack for this to fit. it was installed on a 5.9 L dodge durango.

Comments about Dayco No Slack Automatic Belt Tensioner, Light Duty:
The product is priced well and looks like a high quality part. After a short time the idler caused a rhythmic belt squeal. I took it off to inspect it and found that there were imperfections formed by the casting of the plastic. It was a small ridge that went across the pulley, most prominent on the inner edge. It wore my new serpentine belt just enough to make noise. When I returned it the replacement unit had the exact same imperfections. I used a small, fine file to de-burr the new pulley and installed it. So far it's quiet, but we'll know soon...

Comments about Dayco No Slack Automatic Belt Tensioner, Light Duty:
I replaced the tensioner, worked really well for one week.. It is all over the place worse than the 11 year old tensioner. I saw some slight movement in the original and decided to replace it. I also replaced belt pulley and power steering pump and pulley at the same time... New belt was also installed. I will replace with the same model, maybe it was just a bad one..

belt tensioner is reasonably priced,easy to install. Bearing on idler seemed as loose as the old tensioner but spring tension was much greater. Don't know about the durability yet(obviously)

Q:
I currently have a belt tensioner that is sticking and dosen't seem to have any spring to it. When I changed the Idler Pulley and releaved the tension it just sat there and did not go back to the original location. My current tensioner is not sealed is this typical?Asked on 4/24/2011 by Dave from Bloomsburg, PA2 answers
A:
It is shot, take it off and recycle it, if it sticky, it no worky! Yes, it is sealed or supposed to be, replace your belt while you are there because running with lower tension could cause slippage and burnishing which will shorten belt life drastically.Answered on 12/28/2012 by Dodge Boy from Cincinnati, OhioCUSTOMER CARE

With out the presence of your vehicle we would not be able to properly diagnose it nor provide you with a 100% answer. We would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed that may not solve or be the problem.Answered on 4/27/2011 by David the Dynamite Parts Guy from AAP
Q:
i have this loud continuous squeek in the front of the motor . thought it was a pulley replaced powersteering pump (pulley) water pump was bad so replaced tha pulley . replaced the idler and tensioner pulley. new alternator so that pulley is new.. the actual tensioner is all that is left to replace .. could this solve my squeeky issue??Asked on 5/23/2010 by big k from smyrna3 answers
A:
Stop wasting your money, remove the belt and spin each pulley to isolate the squeak, sounds will resonate inside of an engine compartment masking the source. if you want to cheat before you pull the belt, buy a can of silicone spray, install the long red nozzle on the can, and delicately spray each component with the engine running, when the noise goes away after the spray you have found your source. *******keep your hands away from moving parts and do not be too liberal around the belt as it will carry the silicone spray and coat the other components. if it still did not help, check the alternator first as it has sealed bearings in the back of it that silicone spray will not affect.Answered on 12/28/2012 by Dodge Boy from Cincinnati, OhioCUSTOMER CARE
A:
Replacing this pulley may help, but the squeeking may be coming from the belt itself.Answered on 5/24/2010 by Mike from AAPA:
it could be the pulley or just the belt. Dodge 3.9L belt tensioners are know to go bad after 110k mark.Answered on 6/22/2010 by strohl from pa
