This is great and the input from the comments are very helpful also The bearing and its part number is even given. Thanks

[@BinhNguyen-qe9ph]

Dan, thanks for the video. You made it so simple to replace. God bless you.

[@mikeatv]

[@DantheFixitMan]

+mikeatc33, glad my video helped you out. Thanks for watching! -Dan the fix it man

[@DipstickD]

Great video, many thanks! I was able to do this from above, standing up, I didn't need to take off the skid plate and get underneath. Obviously each vehicle is different though.

[@W7DSY]

Know how much my local mechanic wants to change the entire tensioner assembly? You don't??? Well, anyway it $615!! Thanks for the video.

[@johnlivingston9217]

did they want one of your arms or leg with the cost too? lol

[@brandonwittcop]

They want to swap the whole assembly probably

[@BinhNguyen-qe9ph]

Dan, thanks for a great video.

[@BigJoshGaming]

Thanks this was very helpful. Cost me less than $40 to do this myself.

[@DantheFixitMan]

Thank you for watching! Glad you were able to save some money! Take care, -Dan the Fix it Man

great vid man, my pulley is squeaking big time and its driving me nuts, but this looks like an easy job.

[@DantheFixitMan]

Thanks Matt, Yeah, it's a pretty easy job. Best of luck to you. Take care, -Dan the Fix it Man

[@deegaw11]

What are the symptoms of the tensioner pulley going bad? When temps are cold and I do a cold start I get 1 squeak as soon as it starts then it goes away. Only if temps are cold or a cold start. Other then that the noise is never there. Any idea what that might be? Thanks in advance.

I can't find the tensioner pulley on my 2001 toyota tundra, im replacing the alternator but theres just alot of tension on the belt so i can't get it back on the alternator, plz help

[@darwinalfaro5843]

is posible that tensioner get stock ?? because my truck is making a lot of noise and the tensioner pulley is not moving

[@hendrickliauw5492]

How about if my washer pulley is loose I can't tighten it very well The pulley is shaking now Please let me know what should I do Thank you

[@aatotheron]

In order to replace the belt, would I have to take the fan shroud and fan off?

[@chrisgrier33]

Thanks!!!

I went to replace my serpentine belt the other day. When turning the tensioner pulley bolt counter clockwise it wouldn't budge. Messed with it for about 10 minutes and nothing. Finally I just cut the bad belt off and tried. After that the pulley would lower like it was supposed to. I put the new belt on, but it didn't fix the problem. So I got a new pulley to put on. Now I am having the same problem as before with the pulley not lowering. I don't want to cut the new belt and have to buy another. Can you think of any reason it wont lower with the belt on?

[@DantheFixitMan]

Hi Joseph, I can't think of a reason that having the belt on or off would affect the tensioner not moving. I would have suggested using a longer handle or cheater bar, but you said that you were able to move the tensioner pulley once the old belt was off... The only other thing I can think of is that you might have a bad/stuck tensioner and have to replace the whole thing instead of just the pulley. Sorry you're having trouble with this, I hope you get it figured out. Thanks, Dan the Fix it Man

[@savr4429]

In the process of dealing with a bad tensioner pulley on a '93 4 runner with a 4.0 engine. Bearing is shot. Was able to get the tensioner pulley off from above, but was tough. Did you pull the driver side tire off or the engine guard underneath to get access?

[@DantheFixitMan]

Yes, just the skid plate was all that was necessary for access from below. Thanks for watching! -Dan the Fix it Man

[@savr4429]

Thanx, nevermind my question on the bearing part. I saw your comment below on the bearing.

[@jmoo72]

Thanks Dan almost paid the dealership $900 to do this for me! but ill just do it myself now

[@fukluk88]

Is it just my Tundra or do all '06 4.7 L quad cabs get 10 or less miles to the gallon?

[@joerodriguez1797]

My new pulley is tighting up on the road, having to stop and loosen the nut...why is this happening?

[@brandonwittcop]

Figure it out? Mine is too

[@ko6128]

Do you think your asking for trouble by not replacing the entire tensioner assembly?

[@DantheFixitMan]

It's been over 5 years since I changed just the bearing and it's still working great, but I think it would be a great idea to change the entire tensioner assembly. I was probably just trying to save a few dollars at the time. Thanks for watching! -Dan the Fix it Man

[@ko6128]

@@DantheFixitMan if the belt has the right amount of flex/play/tension seems you’ll be ok not changing the entire tensioner assembly. I replaced my pulley only and the grinding noise is gone.

[@OverlandCO]

Where did you find the bearing? And what size is it? Thanks

[@DantheFixitMan]

+Danielmires I bought the bearing at O'reilly Auto Parts. The pulley that they had listed as the replacement part was wrong so they just looked at the numbers on the bearing and were able to match it. Sorry, I don't remember the numbers or the size of the bearing. Thanks for watching and good luck!-Dan the fix it man

[@skippyskoo]

The pulley I took off my '03 4.7l is 4". AutoZone & RockAuto sell 3.5" replacements. Also the full tensioner assemblies they sell have 3.5" pulleys. Guess I'll be changing out the bearing.

[@donatels1]

NTN 6203Z NSK6203Z TIMKEN 6203 SKF6203 ZZ etc. Found NTN6203Z laying around in our shop. Pressed out and in. Had to re-adjust bearing to be perfectly straight.

[@wreckanchor]

@@donatels1 thank you

[@geoming3458]

When the belt is off should the tensioner pulley spin freely?

[@DantheFixitMan]

Yes

[@geoming3458]

Thanks bro.

[@patrickcrow5042]

Anybody with the part number for the bearing?

[@DantheFixitMan]

Sorry Patrick, I wish I would have thought to put the part number for the bearing in the video at the time I did this job. If you're not near a parts store that you can take the old one in to match it up, it might be a good alternative to buy the whole pulley with the bearing. I think it was pretty inexpensive last time I checked. You may also be able to find the replacement pulley online and see the part number on the bearing itself if the picture is clear enough. Again, I am sorry I didn't put the part number in the video. Best of luck to you. Thanks for watching! -Dan the Fix it Man

[@muunokhoi]

Thanks! I learned what I needed to know. But the music is too loud hard to hear you sometimes and really, who needs music to fix a pulley?

[@DantheFixitMan]

Sorry about that, I don’t put any music during the main part of my videos anymore. I can’t change that one either.

[@muunokhoi]

@@DantheFixitMan not a problem. I’m just grateful for the instruction. Headed now to OReilly’s :)

[@Wolverines1]

Thanks for posting. Vid would be better with out the crappy background music.

[@DantheFixitMan]

Thank you, and thanks for the feedback. I have been leaving the crappy music out of my newer videos. :) Thx again, Take care, -Dan the Fix it Man
