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!

You have teaching skills to be proud of. Don't stop teaching, be it cars, boats or political classifications. You have the gift of clarity and succinct, interesting delivery. Subscribed.

Thank you for showing how to replace the tensioner belt

[scottschmitz]

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

[eriksoul]

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?

[raulbarrera]

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

[rudyfonseca]

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

[ankitpal]

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?

[raulgutierrez]

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

[manny]

Is it suppose to bounce back and fort a lot

[linnuerichardson]

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

[LubaLuba]

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

[xvidsionfiles]

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

[bigragu]

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.

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.
