Diagnosing a failing belt tensioner pulley

[ravenXO]

ya know ive done much larger jobs but this is something i didn't know how to properly diagnose and need now. Thank you so much for this . I appreciate this approach to teaching and its methodical adaptation.

I’ve been searching for someone to recreate this noise for weeks. Thank you! I finally know I’m not crazy, could not pinpoint that sound from anywhere

[jamesortolano]

Much appreciation, great video, as a ford man myself .

I’m one of those guys that tries to save a few bucks and so instead of replacing all the pulleys, I just replace the bearing itself which is much cheaper. Replacing all the pulleys with the name brand Motorcraft can really get expensive. On the other hand, replacing with an aftermarket pulley can also be inferior to Motorcraft. If on a tight budget, you can also remove the bearing cover and pack with grease.

Nice ! My 06 has a belt noise when cold or wet Went away this summer Came back when weather got colder. I put a new belt and tensioner pulley and other pulley, can’t remember which about 60k miles ago. I order the whole kit now to do it all. Well see which is bad and causing it when I dig into it. I think it’s gonna be a JOB considering how tight it is in there. Just got done doing spark plugs lol

Simple direct and to the point, great video

I'm having the same issue, thank you for the help.

my mechanic quoted me 824 dollars to replace the harmonic balancer and the alternator as it was chirping over 2000 rpms, i did what you said to do and hand spin and ill be, the lil top pulley was noisy, all fixed 18 minutes and 37 dollars, thankyou

So helpful, many tks for sharing this look forward to more vids 👍🫵

I had to replace my alternator. I decided might as well replace this and the idler pulley. I can hear a similar noise.

I have to replace mines. How many miles do you think I can drive?

[davidanthony]

Do you have a video showing how to change it out?

[georgebarker]

very simple easy to understand. thanks

[nevinkuser]

I've got a terrible noise like that and I'm suspecting the same. Thanks for the vid 🤙🏼

Also not just the sound but new ones or ones that work properly dont spin 50 rotations like the worn out one which is clearly lost all of its grease, they spin 2 or 3 rotations around and very very quiet..you dont want either end of the spectrum, a seized one that doenst spin at all or one like that in the video that spins too much.

In my case it was my water pump pulley. I changed it last year. Now its a similar noise but the noise starts only after the engine runs for 10 minutes or so. I suspect the tensior pulley because it see some scratches on it which usually means its loose due to a bad bearing. Which means ill also need a new belt too

[patrickdelapp]

That is one way it goes bad. Another one is that the spring inside the tensioner looses some of the tension it puts on the belt. Replace mine at 200k with the belt. New tensioner had twice the force as the one I took off. (Spring wore out)

3 weeks ago I needed this. but everyone said power steering

Thanks for this, got this same exact noise on my 07 TL Type S. 4k RPM and up that noise would come on. Especially when I let the gas pedal go.

Great video. You know, we were on the moon in 1969. You’d think by 2023 they could make quality automobile parts that LAST instead of junk. 🤔
