Lexus RX 2004-09 :: Chirping Noise Coming From Belt Tensioner Or Idler Pulley
Jan 5, 2015
So from reading around a lot, it seems like the chirping is from the belt tensioner or idler pulley. That said, I've not been able to find anything definitive. I tried to do the water bottle squirt test (from Gates' youtube video) and either I did it wrong or the chirp did not go away implying the issue is not the belt. While I was looking in, I could see the tensioner shaking some.
If my tensioner should not be moving, do I just need the pulley or the pulley and the mount?
- Pulley [URL] ....
- Pulley and mount [URL] ....
Also, if the above items will fix the chirp, which brand would be best?
2007 RX 350, 113K.
Chirping gets worse as it heats up. Seems to happen independent of ambient temperature. Purchased a year ago so unsure of the history of part changes.

2002 Camry 4 cyl. Can the idler pulley alone be replaced on the serpentine belt tensioner? I noticed a very slight side to side play when I had the belt off. No noise from it. When I looked at rock auto, they sell the whole bracket with the pulley.

My tensioner pulley is making noise.I replaced the rear idler pulley (can't get to the front one), but still have the noise. Mention a DIY for replacing the tensioner pulley bearing. A part number for the bearing?

I have a 2003 Santa Fe 2.4. Couple days ago my idler tensioner pulley or whatever its called seized up and took the belt out with it. I got a pulley that resembles it from Autozone mind you that it was the only parts store that had one in stock even Hyundai didnt have the part. The only difference is the hole size for the bolt is about 1/4 inch bigger then the stock pulley. Is there any chance I can get a spacer and make up for the difference?

Ok I have a 2002 f250 7.3 4x4. The belt starting to shred and make a whiping sound at highway speed. So I replaced the idler, tensioner and belt. That was not the problem it still making noise so next I changed water pump. Still not it so I changed a/c clutch, bearing, and pulley. And It still not fixed. Right now the back of the belt is turning black on the wrighting like a pully is locking up. Also the front edge of the belt is starting to wear. I only have 255,000 miles on the truck and has been well maintained.

Looking for how to's out there on how to get all of the fan shrouding removed? I am trying to do my idler and tensioner pulley bearings and those shrouds really make it tough.

I have a 2008 F-150 with a 4.6. I have a sequel and I believe it is the belt tensioner pulley and / or the idler pulley above it. Looking for proper procedure to change one or both. It is pretty tight in there. How much stuff do I have to remove to get in there. Should I replace both pulleys at the same time.

I have a noise coming from the front of the engine. The noise stops once the the thermostat opens and the water pump starts circulating coolant.

I have 1997 F250 LD since i bough it has been doing this chirping sound coming from the serpentine belt and the pulley area but when the truck has been working for 15 - 20 min it goes away
This is apart from the from the problem before I think the fan clutch is broken because when I start the truck I can hear the fan going at the same speed of the engine is that normal ? even when the truck is cold

I have a 2006 Camry 2.4l and I'm hearing a loud noise coming from the idler pulley on cold startups when I put it in gear. I don't hear it when it's in park. The noise gets worse if you turn the a/c on. I have replaced the belt, idler pulley and top motor mount. I took the belt off and cranked it when cold and there was no noise even in gear. I can see the idler pulley moving and can confirm that's the noise but what it causing the belt to make it do that? Could I have bought a defective idler pulley?

2006 6.0l ... I've read all over for tips on routing this belt and everyone plays it off as being some simple '20-minute' task. I'm on my 4th hour on this now.
I can't figure out how to route the belt around the tensioner pulley, circled in the picture (from another thread). Everyone glosses over how to do this and I can't figure it out.
It seems like the only way to get it on is to bend the belt and slide it between the pulley and the block, but that I just can't reach the blasted thing.

I noticed my engine whine more than it usual since the last few days. So, I took it to the dealership and have them check. They said that it is the idler pulley going bad. Just want to see some info on diagnosis.

In a few weeks I will be bringing my new to me Ranger back to the great state of Texas. The truck however, has a squeak when running, which I think has been concluded as the idler pulley for the timing belt. Well, I'm nowhere near the truck still and in order for it to get here it will need to be driven half a day to reach me, at which point I could do all the work it needs done.
My question is: Should I take the risk and have it driven here before the belt change (I did look at it while I was out there and it's already cracking pretty good), or should I go ahead and have someone get the belt done at a shop? It's less the belt that concerns me I think, and more the pulley, even though it's just started squeaking in the last 1000 mile.

My 2007,4.6 is making a whinning noise from the front of the engine around the idler/tensioner/alternator. What I have read it might be a problem with the alternator getting cold, I forgot to mention it's cold up here. Fixed by changing the alternator and did the noise come back as it seems to be a design problem?

Doing some charity work on a '04 5.4. Noticed top right idler pulley was sitting on a 45* angle, figured it was shot and decided to replace it. The bolt broke. Borrowed an Easy Out. Short version, I have a very messed up bolt hole. Tried drilling and tapping but couldn't get it to bite and was scared to go bigger. I don't know if the threaded part pulley actually mounts can be replaced and if so how to go about it. Not sure how much deeper I can drill if it can't be replaced? At a standstill.

I recently had a good amount of work done to my Mk4 R32. Last night on my drive home from the stealership I ended up with a passenger headlight out and a very loud clicking/ticking noise which seems to be coming from the Serpentine belt area. After closer inspection it looks like the tensioner lines are't lined up which means my belt and tensioner need to be replaced? I'm not sure, but I have a video and this picture.

During the 120000km (75000mi) service my Toyota local service said I have a noisy Prius and that the sound is from the belt tensioner bearing.
As I bought it used and always heard the same sound. I've made a video ....

i just recently went to a mechanic check out my wife's car cause it was vibrating really bad, and a pulley was making a lot of noise... they told me that the alternator bearings were shot, and i needed 4 motor mounts, long story short i changed the alternator.... it wasn't the problem... had them check it again, they said power steering.... i didn't want to waist a couple hours of work again, i checked it myself like i should have done in the first place... and found out it was the tensioner pulley.... so can i get any pointers on how to change the tensioner pulley, cause i tried and i lacked about 1/4" of space to get the bolt out... do i need to drop the engine or raise it? if so how.. 2005 suzuki aerio 2.3L .....

My Ex is missing the label showing the serpentine belt routing diagram. I pulled one off the Autozone website for V10 with AC. It showed that there are 2 idler pulleys (one on the left and right side of the alternator). It also has the tensioner pulley.
I only have a tensioner on the left side of the alternator. The one on the right is missing. There appears to be a threaded hole where a pulley should go. Since I bought this used, I thought the previous owner took it off.
I used the bolt from the old tensioner pulley I replaced for the hardware and put a new pulley on.
I also looked at other V10s on used car lots and none of them had the pulley to the right of the alternator. Should there be one there?

The idler pulley bearing of my 3.3l Sonata NF has become quite noisy, as though it is running dry. Does this necessitate a complete pulley replacement or can it be disassembled and the bearing repacked (or if necessary replaced). I am becoming concerned that the bearing may fail altogether soon.
