How to Replace 2007-12 Nissan Sentra Serpentine Belt Tensioner

Buy Now!
New Accessory Drive Belt Tensioner from 1AAuto.com trq.video/ia-1...
The tensioner is a springed device that keeps the serpentine belt in your vehicle at the correct tension to keep it on the pulleys, without being so tight that it breaks. Eventually the tensioner may become worn, loose, or stuck, resulting in belts that squeak, slip, or fall off. This video shows you how to install a new TRQ tensioner pulley in your 2007-2012 Nissan Sentra.

Is that the only way to remove it

[@ianbronkhurst3639]

The best video on the net showing Nissan Dualis tensioner replacement in an easiest way in detail... thanks

[@GemGreyHam]

Thank you for taking the time to prepare this video....excellent for young adults who are starting to learn how to fix their own cars!

[@funkycarlover]

Thx had a squeaking belt/tensioner & didn’t know how to access the tensioner bolt, this helped a lot

[@socalskater15]

Do you have to lift the engine?

[@Laz3rs]

Really appreciate the catalog of quality videos you guys have. Because of that I made sure to source all the parts I needed from you guys. Appreciated!

[@ronaldbartcher5672]

Thank you so much for this video. It would be impossible to change the tensioner without moving the engine and your video showed exactly how to do that. One correction: the tensioner bolt is T-50 not T-45 (at least it is on my 2007 Nissan).

[@petew8238]

Great job and and video. Saves me time trying to figure it out myself on these cold winter days.

[@chesh3712]

You can access the belt via passanger side, remove tire and spalsh guard.

[@deadmoney2093]

Is it necessary to swap out the idler pulley for a new one too ? Or just replace the belt tensioner only?
2011 versa 1.8 hatchback

[@Pops-vb6ni]

Please make a video that shows the hole that you used to access the hex bolt. I have watched several videos of this procedure, and there is no hole in the fender well of any Versa hatchback. I am also well into replacing my a/c compressor, my belt and tensioner. There is no hole in my fender well for accessing the tensioner hex bolt. All I need to see is the hole, or did you drill a hole?

[@MrFatboy192]

Thanks for the great instructional video! I've just repaired my 2008 t31 X trail, slightly different I had to raise my engine up about 50mm so I could get onto the torx bolt, I can confirm it is a T50 not a T45 on my engine although I used a T45 at first to get it out.

[@tylerwilburn96]

Y’all lowered the engine to access the tensioner, then lowered it again to put the motor mount brackets back on. This means y’all jacked up the engine and didn’t include it in the video, otherwise the brackets wouldn’t have lined up

[@renostubbs8504]

Excellent video man, I am experiencing this issue right now,however, is it necessary to gain access to change this part the way you did it? The reason I am asking is that the mechanic went in from behind the steering wheel. Just want to know the safest way to avoid any future issues.
Thanks for your time and experience

[@markygutierrez4195]

Its a T50 on my Sentra 2011. T45 was too loose.

[@lowspeed2000]

So it's safe to raise your engine from the oil pan? Won't it get damaged?

[@javiersolis9141]

I have the same nissan car with the 2.0l I had to jack the engine up to do the exactly same thing. So the only thing I could come up with is you must have lifted the engine up alot to have it go down to go through same hole to Extract Bolt out of tensioner, video did help some thanks

[@NeutronX101]

Followed this step by step and did the job. You guys are awesome. Only i needed universal joint socket adapter to get the T50 in otherwise would of not gotten the job done.

[@ryanwyrick6947]

how much is the engine being lowered 1"? 2"?

[@nealdunleavy8267]

All The way Dope Video Kind Sir

[@redskiclayton]

Great video...
My task at hand tomorrow will be tapping the A/C compressor bolt holes and installing Heli Coils because the bolts snapped from the failed tensioner :(

[@namelessman0445]

For those of you coming here solely to do a belt swap: take off your front right wheel, and with a 14mm wrench, pull the tensioner towards the back of the car. You can then rest the other end of the wrench on the nut on the pulley wheel below the tensioner when taking the old belt off

[@earlhoytiii3243]

So first you snug the floor jack up against then engine oil pan, then you said "lower" engine after the engine mount is removed to align tensioner bolt with hole in frame, but then during reassembly you say to "lower" the engine again to reinstall engine mount, so something seems off if you reverse everything to reassembly. Did you actually "raise" the engine to align the tensioner bolt with the frame hole? Or at some other time?

[@blakeclaterbaugh6122]

I’m about to tackle this and have the same question.

[@lowspeed2000]

I think they missed one raise. Between putting the pulley and putting the belt back. So at the point you need to lower or raise a little more to get it aligned.

[@RobertoJ3rd]

5 star video instruction!!

[@papaP24]

Appreciate the detailed video , going to source from you guys in the future, thanks again

[@marioquesada4624]

Thanks to your video, we were able to do the job!

[@ropaswan]

I have a 2007 Sentra 2.0L. I followed the video exactly, but couldn’t figure out how to move the tensioner to get the belt off. I borrowed the serpentine belt removal tool from Auto Zone, but the 14mm claw wrench only adjusts by 90 degree increments, and when I am finally able to get it on the tensioner, it won’t move because the angle is bad and there’s too much stuff in the way. What tool do you use to get the belt off? The video says a 14mm wrench. How long is it? And where do you stick it in from?

[@ldsanela]

Did you figure out how to move the wrench?

[@johnstudd4245]

My 08 versa is set up much differently than that with motor mounts a fluid tank.
