I've got more than 300K miles on my 2001 Tundra, and the idler pulley (grooved) was the culprit. Used your other video to replace the serpentine belt, hoping that was it. No dice. Came back and found you had made this additional video. Replaced the top pulley (like you did) and my truck has stopped screaming at me (it's been loud for almost 50K miles). I had no idea it was going to be a "simple" fix like this. Appreciate the thoroughness of your videos and the parts and the links to purchase them. Keep it up. I bought the Tundra with 26K miles on it in 2003, and have put nearly 280K on it myself. It's a great ride (still!). Glad you're enjoying it, and helping out us novices who don't know a lot about some of the fixes we can do ourselves.
There is a Toyota TSB(Technical Service Bulletin) out on this issue. Its the 2uZ-FE Accessory drive belt noise. My 06 has this issue as well and the fix seems to be replacing the Tensioner pulley and adding an upgraded bracket. Part numbers are: Tensioner pulley - 16620-0w100 and the new bracket - 88431-0C012. I am getting the parts together now but the install will be a bit of a pain. I have to remove the fan, fan shroud, radiator, alternator, power steering pump, timing belt cover, air box assembly just to get access to remove the tensioner pulley and add the new bracket.
I had a bad idler and I didn't get the same pulley in the mail so I bought just the bearing and pressed it out with my harbor freight ball joint press. Ended up only costing a few bucks . Keep up the First Gen content 🔥
Nice, yeah I considered doing that but I just kinda wanted the easy route this time lol. Maybe I'll consider doing that on the ones I took out and keep them as replacements. Thanks for watching!
@@JDMDrivewayIf you go that route, leave the bearing in your freezer overnight and it will press in like butter. Forgot to do this? Turn a can of air duster upside down and spray your bearing to chill it to -40. No press needed.
Awesome. All to be had from up top. Small squeal days later broke my newer (2k miles) Gates belt. Tensioner pulley seized 2 blocks from home. Just installed new aluminum radiator, wish I had done this at that time.. but timing belt getting due, was waiting- and lost. Wrenching today. Thanks!.
I love this channel dude. I have an 04 access cab. I have had my idler pulley changed and the squeak got waaay better. There was actually a ball bearing loose in the pulley making all kinds of noise. Now it’s just a very slight squeak as you said on cold mornings. So I’ll probably take a look at the tensioner one
Thanks for sharing. I did the tensioner pulley and had the same problem finding the right part. Then I learned that Toyota discontinued the original assembly and wants you to replace the whole thing, which is a major pain. I ended up buying the OEM NSK bearing and swapped just that, reusing the old pulley etc. It was actually very easy, no press needed. I found a matching nut, knocked out the old bearing and gently tapped in the new one. Saved a lot of money and time. Another thing, to get more torque on the left handed bolt, I used a piece of wood to block the tensioner pulley and was able to torque it nicely.
Would of been nice to have this last month. I have already replaced my idler pulley and spend about a week researching since I’m not much of a car guy. Great video you summed it all up in 12 mins 👍
Thanks for the video; well done! My 2003 Sequoia limited 4wd had the same issue. I replaced the belt and the tensioner pulley and found the same pulley size issues but you saved me a ton of time. The Sequoia match was the Gates 36119.
I’ve had the worst luck with plastic aftermarket pulleys in the past. I’ve had them go out without warning leaving me stranded on the side of the road. After getting my tie dirty a few times fixed my break downs, I ended up putting OEM metal pulley back on.
I was a little worried about the quality of these aftermarket ones as well, but after getting them in hand, they are also solid metal. The longevity of the bearings is the main thing that I am worried about. Thanks for watching!
this is exactly what I needed for my 2003 Tundra. according to Toyota they call it the automatic belt tensor pulley. and I'm glad you addressed it in the video. only one that would fit was Gates because of the inward groove where the bolt and the nut fits in. right now i found it on Amazon for $43 i believe. AutoZone gave me the run around and O'Reilly's said it was something that they would have to specially order
SOS! I am looking for the stand alone tensioner pulley like you found, but for a 2019 Toyota Tacoma 3.5L. Trying to avoid ordering the wrong one. Most of what I find online is the full tensioner pulley assembly including the pulley.
So helpful, I have a first gen tundra but I'm not mechanically inclined, so doing my own work is daunting. I'm a computer technician not an auto technician!
I've got a 2005 and had the same issue but I ended up just replacing the whole tensioner assembly and the idler along with a new belt. It's a bit more involved but with 240k miles on the truck who knows if the tensioner was still putting proper pressure on the belt.
I had considered it, but that seemed like a ton of work. I will replace the tensioner next time I do the timing belt and I have everything apart. Thanks for watching!
Thanks for posting. Would having the belt back installed, allow you to tighten up the belt tensioner pulley without it moving on you? Great informative video Sal. Cheers
I had thought about that, and I also thought about wedging something next to the pulley to tighten it more. I still haven't done it, but so far the pulley seems to be performing well. Seems like a good idea to do though, thanks Daryl!
Be glad you didn't have to replace the spring assembly of the tensioner yet. What should have been a 5 minute off and on with my 05 Sequoia became 3 hours of labor from an experienced mechanic. Fan off, timing cover off ,alternator pulled away and shifted away just to get to bolts on the tensioner. Some of their design choices really fry me, few as much as this one and them locating the starter under the intake manifold.
Awesome job!! Thanks for sharing I’m going to be doing this. Glad you mentioned the tip about the size differences. 👍👍 it’s definitely going to save me time and headaches. 😂
Thanks, good video. I have my original owner 2002 on the road right now and gradually got a pretty obnoxious noise on our trip from FL to TX. I can see that the tensioner pulley is out of whack. If I was home I’d fix it myself, but am going to run it over to a Toyota dealer and have them change it out. Hopefully they won’t hose me too badly.
an absolute essential video. I have a 2003 and can not find the proper pulley from autozone. I live in Mexico and cant find the Gates pulley. At my wits end trying to get the truck fixed.
Hi Sal. I bought the pulleys you recommended. The Dayco Idler pulley does not fit correctly on my 02 Tundra. The bolt is too big for the whole in the bearing. I ended up just using the old one for now. Seems like these are dealer specific parts. Love your channel! Thanks!
Crap that sucks. I'm sorry to hear that. It's weird it wouldn't work on your truck, but it was good on mine? Going the dealer route will guarantee that it will fit I guess haha. Thanks for watching, and sorry again about the bad info. Not sure why that would be
Great video-thank you for the guidance! The belt tensioner pulley should spin freely without the belt on there, right? Mine is seized up, so I'm assuming that's my big issue with squeeling. I plan on replacing the tensioner pulley and belt.
Great videos! The production value is going way up! On my 02' SR5 truck's side mirror, the is glass detached and light indicator is loose. Any tips where to find a replacement part with the power signaling option? Thank you
I googled and watched multiple videos on this and unfortunately your video never showed up in the results. This is unfortunate because no other videos point out that the pulleys are different and only the gates has the right size and taper. The autozone and o'reilly pulleys do not fit. Wish I had seen your video before buying the wrong size. Still cheaper doing the repair myself though. Thank you 👍😀
Do you think this would be the same for a 2002 sequoia Thanks for the video I’m glad I found this channel it looks like we have the same problems on our trucks 😂
I wouldn't recommend aftermarket pulleys. I had a dayco one and made noise after a year and put an oem in. the price is because of the quality and how long it will last you
Im struggling to get my belt on with this pulley. The one i took off is about 10 mm smaller. But even with the belt in the video I can't get it to go over my idler pulley with full travel of the tensioner.
That's weird. I'm no expert on these engines so I'm not sure on why your pulley would be a different size than mine. Hopefully you're able to find the correct one for your truck. Thanks for watching
Hey , what did you do to resolve this… I encountered the same thing, and I swapped out the larger pulley to a smaller one, and I think that will solve our problem. The replacement one came with a smaller pulley.
Hi Sal. I have been researching tensioner pulleys. Cheapest Toyota OEM is $89 not incuding tax and shipping. How is your Amazon Gates holding up? I am just starting to get a squeal now and then on cold start-up. Is it best to replace everything at once? Truck has 185k. I read something about cheap Chinese pully to have triple bearings. Thanks for your insight. I have been really enjoying your channel.
The gates has been working as advertised, so no complaints there. People will argue that buying an OE bearing and pressing it in saves money and gives "factory reliability", but that seemed like more of a hassle than it's worth because I don't have access to a shop press. With that said, after replacing the belt and the 2 pulleys in this video, I still have a squeal on cold mornings. I'm thinking it may have to do with the fan/fan clutch, but I haven't been able to nail it down. So, replacing everything at once might be your best bet in case the one pulley you choose to replace isn't the fix. Thanks for watching!
Thanks for responding 😀 . Looking forward to your next video when you find out what it is! I was wondering if mine was the alternator. The squeel went away by itself, but it's been in the garage since. Appreciate you!
Bro! I removed my idler pulley and put on the replacement (Murray), and now the pulley rubs that small coolant line thats directly behind the pulley. I figured it was a jenky aftermarket part, so I pulled it off and put the old one back on... and the old one is rubbing too! So i figured i must have dropped some sort of spacer or washer or something, but I can't find any dropped parts, and I dont see a spacer/washer in the video, nor in exploded diagram pictures. Do you have any idea wtf is going on here????
@watertiteman dude. So theres a little brass washer/spacer sleeve jawn that apparently popped off along with the OG pulley. Find that and reinstall it before putting the replacement on. It may be stuck to the OG pulley, even
Yep, the pulley with the bad bearing can be unbolted and replaced while leaving the spring tensioner bracket and assembly. Hope this helps, thanks for watching!
Unfortunately no, I think it's coming from my fan pulley. I have the new part and will be replacing that at some point here, just dreading it because it's basically a timing belt job. Thanks for watching!
@@JDMDriveway my 02 sequoia started squeaking and now chirps under light acceleration or while cruising with light throttle. Assuming it’s the spring in the tensioner and not looking forward to that either. Keep up the vids man!

You can also pull the small cover on the tensioner pulley and regrease the bearings. Extends the life of the pulley.
