Very good video of how that problem was solved. Keep up the good work.

[@CarsNToys]

Thank you! Appreciate the feedback

[@marinaleighc269]

Your video showed me the ONE thing I'd missed when trying to install my Serpentine belt, leverage. Now, I'm back on the road again and I'm feeling pretty good about myself because I'm a mom who didn't have to call a mechanic. Thank you!

If a tensioner is suppose to have 40lbs on a torque wrench then why the heck cant that be done on vehicle instead taking it off, I know some just love taking things apart but some of us dont like taking stuff apart that dont NEED to come apart...........

[@georgegeorgel7254]

My car battery fail to charge and i thought its the alternator but it actually the drive belt i have to replace the drive belt and tensonier as well just in case

How to remove pullies to fix air conditioner,diagram !

[@stevewaclo167]

On my 3.5 Altima Coupe, one fastener is behind the PS pump pulley. 😟. Looks like crow’s foot time and just hoping it goes finger loose quickly. Also, my tensioner ($20/sitting on workbench) has 135k on it with a slight wobble on hand inspection. The belt I R&Red I had 5 years and 60k and all ribs were seriously cracked. Will do tensioner when motivation strikes. 😀

2002 Ford Taurus,how to change them.

[@eriksoul7664]

So far your the only vid that shows auto tensioner release. Now I need to know if mine turns right or left.

[@bigragu98]

Good video. Next time you may want to thread a few nuts onto the studs before you crank the vice onto it. That way the vice would tighten up onto the nuts and not potentially bugger up the threads.

[@jellybon]

That's a good idea! Thanks for this

[@calvinludwig9209]

Can you show me how i install belt kia forte 2012

[@jordanadams4360]

Good tip

[@jovannygalvez8191]

Awesome video thank you for posting! I

[@CarsNToys]

Glad you enjoyed it!

[@Saroeumyim]

I never had to go from the bottom to change out the tensioner. U can use a 14mm ratchet wrench on the tensioner and the 12mm bolt is accessible with a deep socket+1/2 to 3/8 adapter.

[@sanantonioawareandprepared8206]

My tensioner wont tighten up, belt pops right off every time i start my truck! Thoughts? Recommendations? Also, its seems to be a bit crooked on the spring. I don’t remember it being like when when I replaced the s belt a couple years ago.

[@TrendingPoonai]

Superb explanation 👌👌🙏

[@mrrbrown86]

Great content but my tool will not fit so I can change my belt like yours I dnt kno why i am having this problem, i have a 2001 acura mdx but i see noooo videos on this for my year, I dnt kno what to do 🤦🏽‍♂️🤦🏽‍♂️🤦🏽‍♂️

[@amrindergill7218]

Use two combination wrench ... Put one on pulley bolt then stuck wrench’s other end into longer wrench’s round side ( be careful) ..u’ll able to release without spending money on special serpentine belt tools

[@jameswaugh115]

My 08 c300 Benz has a strut attached to the tensioner..the tensioner is worn out & I don't want to put that shock back on..will it run ok without that shock?

[@zoneonthetrack4499]

Can the Sepertine belt tensioner pulley be remove

[@scottschmitz6061]

Does the pulley have any play in it, for it to wobble. I jusg bought a new tensioner and the pulley wobbles a lil bit with it off

[@georgele872]

thanks you for the video absolutely help

[@peterkimeu9941]

what is wrong with a mistubishi outlander belt when it jumps off the poewrsteering pulley and also wearing out fast in less than a momth

[@rudyfonseca2582]

Should a tensioner spin freely/endlessly, or should it stop after a few turns?

[@GiveMe10Fitness]

I have to change my tensioner on my 06 Acura RL. Your video explained in detail with very easy instructions. The best video. Thank you 👊🏾

[@manuelllamas6148]

I also had same vehicle. Very reliable and smooth riding.

[@ankitpal5365]

Hello, actually I want to use a belt tensioner for adjusting a metallic cutter in a pulley system. But I am not able to know how to do so. Can u guide me a bit?

[@MrPrios1]

I knew someone else knew how to test it real easy. Thank you. 40 FT-LBS

[@raulbarrera3256]

Hi, good afternoon I have a question can you let me know where I located the tensioner belt of a Nissan Quest SE minivan 1999 and thank you

[@paul-andrelarose3389]

Much of my problem was to access idlers/tensioner and determine which one is actually the tensioner and the size socket to use. Is the tensioner bolt size generally identical for various vehicle models? Very useful video. Thank you. 2021/06/06. Ontario, Canada.

[@EarlCollinsworth-yq2yg]

Yeah, how about checking and replacing the needle bearings on those pulley if possible?

[@charismatica8697]

Please show how to remove the tensioner wheel.

[@xvidsionfiles8613]

my tensioner popped out ward and I see the spring of the tensioner

[@xvidsionfiles8613]

if I see the spring while driving....is it broke?

[@LubaLuba1]

What about town and country mini van it would be huge help

[@albieoval1657]

9:20 couldn't the 40 ft lb. Torque check also be done while the tensioner is still attached to the engine?

[@linnuerichardson6826]

Goog night can i see the tensioner for the 20 16 probox please sir

[@qwertyajb]

Hey man, great vid. Helped me understand belt tensioners, maybe you can offer some advice... I have a project off road go kart with a 200cc engine from a generator. I want to fit a tensioner because the shorter belts aren't thick enough. Do you have a diagram of how tensioners work to help me build one for this engine? Or could you take a look at some photos of my set up? If anyone reading this can help then please do, I'm new to all this!

[@kalindakamwale3929]

I need a belt tensioner for Mazda mpv 2001 l live in zambia

[@raulbarrera3256]

Thank you for showing how to replace the tensioner belt

[@raulgutierrez2377]

What size what size is the bolt on the tension belt assembly

[@manny903]

Is it suppose to bounce back and fort a lot

[@futureshock7425]

At least Subaru gives you some room, Nissan requires you to raise the engine and remove the engine mount

[@CarsNToys]

Bummer. Yes, on some vehicles it's incredibly, incredibly tight.

[@RustyShacklefardd]

That’s why I buy American cars

[@virginiacharland9068]

Why does belt keep coming off

[@clydefelton8523]

[@madross1377]

[@Darkdemonoflite]

[@ahmedelhabrush1391]

Thanks It was very helpful.

[@RJManeri1]

Can the belt tensior be installed incorrectly?

[@nando2537]

Hey man can you make a video on how to replace the hid on a TL

[@nando2537]

Never mind found your video

[@CarsNToys]

Sweet.

[@deanjohnson7970]

thank you for that,you explained that clearly I now feel I can tackle the job on my tiburon

[@austogusto5132]

How did it go??

[@antonymorar2883]

Great job! So if my alternator belt is loose. I should check the tensioner for proper torque. Are there any other reasons my alternator belt is loose ?

[@venge1894]

A belt can only come loose if it has no tension (faulty tensioner) or the belt itself is faulty. If a belt is old or damaged, it may be stretched out and no good. L

[@Glenn_123]

Another great video! Excellent job!

[@CarsNToys]

Thank you! Appreciate the feedback!

[@DVLZHAZE]

i have a really bad misfire, checked everything including ecu. The misfire is soo strong it tugs the tensioner back and forth ORRRR is it the tensioner causing the misfire. Guess what i really want to know is if a misfire usually constricts the engine to the point where you see the tensioner pulling back and forth? AC doesn't work, Power steering doesn't work alternator producing only 13.5 volts. but it looks like the misfire is messing with tensioner. but this vid has me thinking that its the tensioner causing the misfire.

[@BillSW]

did u figure it out?

[@coyanelewis]

I hear a knocking sound when I turn the ac on could it be tentsioner

[@whatsupp7539]

Had the same problem on my ford turneo custom long story short I decided to change the crankshaft pulley and the problem was gone now my car is making a squeaking noise/sound thinking it could be the serpentine belt because I saw some cracks on it

[@coyanelewis]

@@whatsupp7539 I found the problem with mine it was the ax compressor

[@christianlee4835]

Couldn't it have been tested o the car?

[@CarsNToys]

Absolutely. I removed it to show the process if it needs to be replaced.

[@johnnydoggs]

1st! I win i win!
