Gates 38285 Drive Align Automatic Belt Drive Tensioner

Nice , heavy duty, perfect fit

NICE! This product is heavy duty, not garbage like so many of the others, it was a simple ten minute job to change. Just a little longer for recirculating the serpentine belt. the perfect fit for my 6.7 cummins engine. Side note it is important to pick a tensioner with a new replacement bolt, you DONOT want to use the old bolt, it is rusty and could break off with a new tensioner. Always replace new with new...

Works good so far. No issues. Good fitment. No squeaks

Excellent belt tensioner, way more quality than the factory one, way more robust and better in every aspect, use on my 2022 ram 5500 6.7 dual alternator.

I installed this on an 06' 3rd gen Cummins. Easy instal and works great. The listing shows and the included instruction say to use the supplied 10 mm bolt...mine didn't include the bolt. The mounting area of the Gates tensioner is thicker and the original bolt isn't long enough. The original bolt is 80mm long...you will need a 90mm long bolt to instal the Gates tensioner. Luckily my local hardware had a suitable bolt. If the tensioner would have come with the bolt like the description says...this would be a 5 star review.

I installed this on a 2012 RAM 3500 with the 6.7L Cummins. This is a more robust part than OEM and uses a metal roller vice plastic on many from the factory. If you have that chirp at startup or stop this is probably the culprit. It bolts right up with no need for modifications to the part or your engine. Unless a freak accident occurred to the tensioner itself and you know your belt is still good, I suggest doing both at the same time. You need an hour, 18" or 24" breaker bar in a 1/2" drive size(this is a must), very small amount of blue loctite(recommended), one beer, preferably a ratcheting 13mm combination wrench, a 13mm socket, a ratchet with at least a 3/8 inch drive(i used a 1/2" drive), and the belt routing diagram for your engine configuration. You DO NOT need to remove the air box, fan shroud, or the fan; you can replace this from the underside of your truck. Remove the tension from the belt by knocking it out of a pulley track, slowly release tension from the tensioner, and then remove the 13mm bolt from the tensioner. The tensioner can be removed from the bottom just by snaking it through some gaps. IF YOU ARE REPLACING THE BELT ALSO>>> Now for the belt, the hardest part is squeezing it through that tight gap betwixt the crankshaft and fan pulley, BE PATIENT, take the belt off of every pulley so it is just you getting intimate with the belt and those two aforementioned pulleys', OR you can just cut it because you're probably replacing it anyways(i don't recommend this in case you were provided with the wrong belt). Check all your pulleys' for wobble/play, make note and replace them then and there if you can. Once the belt is off, take your new belt, I recommend Gates green belt, and put it back through the gap that you just wrestled with or avoided by cutting it; you MUST do this first or you're in a world of hurt. Then start routing the belt around some but not all of the pulleys', as you'll need some slack for bolting the tensioner back on. BEFORE bolting the tensioner back in place route the belt around the tensioner's pulley, failing to do so will cause you a headache you don't want or having to remove the tensioner again to route it because it is easier. Add two or three drops of loctite to the threads furthest from the bolt's head. Ensure you have the locator dowel facing the engine and that you locate the dowel in its guide hole and rotate the tensioner body so you can get the bolt aligned with threads, and hand tighten the bolt to hold it in place until you can get a wrench/ratchet on it and fully tighten to OEM spec. Ensure the belt isn't catching anything, specifically that crankshaft sensor, and that it is in the belt tracks. Apply tension to that newly installed tensioner and route that belt around the last pulley and slowly release pressure on the tensioner. Perform one last Check on your work, this is a zero defect job, because if you did something wrong it is going to cost you money. Start your motor and ensure all your symptoms have been resolved. If so, YOU ARE DONE.

2020 Ram 3500 Longhorn 4x4, 6.7 Cummins fit perfectly!!

Seems like quality piece. Easy install

Perfect fit

The tensioner is built very well and despite the pictures Amazon uses, my part was made in Canada. I like that the Gates part has no plastic. Great design improvement! My original Dayco part had 171K and although it spun fine there was a minor whistling. That was reason enough to replace it. A perfect match for my Gates HD green drive belt on my2006 Dodge Ram 2500 5.9.

easy job

Just what I needed

This part has been working great since purchased and installed. The truck i installed it on I’m very picky about and I would buy this part again in a heart beat
