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 ....
My ball bearing on the tensioner seized and broke the belt. Does that happen all the time?? My car is a CP and right now it's only 36k miles..
View 24 RepliesMy 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?
View 2 RepliesSo 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?

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.
I own a 2008 santa fe SE, the belt tensioner start to making noise recently, just wonder if it's covered under the warranty so I don't have to pay out-of-pocket to get it fixed. This car have 68000 miles so far.
View 19 RepliesI 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.
View 2 RepliesAfter finally identifying a bad serpentine belt tensioner for being the the culprit for my engine noises, my mechanic said that the 'thru-bolt' is siezed. Since the replacement job was at my budget limit he said he doesnt want to get into it in fear that he has to brake the bolt and drill it out (requiring 2-3x more labor cost according to him).
If this is the case, and the 'thru-bolt' is seized, is this in any way something I can make a an effort to tackle? I have a jack and jack stands, and plenty of time.
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.
View 7 RepliesSix months ago my 2005 Honda Pilot got a new timing belt that was incorrectly calibrated. When the Honda Dealer test drove the car, they damaged the values. They fixed the valve damage and gave me a discount on the timing belt. I considered selling the car, but decided to keep it.
Now it's six months later. When driving I hear a "clicking noise". The dealer says that the timing belt tensioner needs to be replaced and that it would be dangerous to drive it at high speed as it is now. The clicking is caused by a worn ??? tensioner.
They claim that the incorrectly calibrated timing belt could not have caused this problem with the tensioner.
I have a problem with my 1997 aerostar. There is a squeaking noise that gets more significant when I turn. I am pretty sure this is the drive belt as the power steering fluid is fine. Should I attempt to replace the belt tensioner and if so is it just the pulley that needs replacing or the whole tensioner. I am by no means a mechanic but can figure most things out.
View 5 RepliesI have a 2012 Camry LE 4 cylinder non-hybrid at 31,000 miles. I was changing the oil yesterday and noticed a repetitive squeaking noise from the front passenger side of the engine. Upon looking closer, the belt tensioner has a constant wobble. Maybe around 1 cm of deflection with the belt. The AC condenser was running. Is this normal? Do I need to replace the tensioner? If so, what the torque spec is for the main tensioner bolt (pivot bolt)?
View 1 Replies2006 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.
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.
View 14 RepliesI have a 2009 Camry 5spd with 92K miles on it. Camry is completely stock and original with meticulous services to engine oil and drained the transmission fluid at 68K miles. I am hearing an engine hum every now and then (although I notice it more often now that I am searching for it) while I am idling. I don't believe it to be engine vibration, rather it is a hum, seems like a belt pulley bearing is going out, or even, and i hope its not, like my throw out bearing in the clutch is going bad.
Only reason I say that is because it makes the hum for a few seconds then goes away, then comes back for a bit. It makes the hum when i have the clutch engaged and when i have the clutch disengaged and a in neutral. I have opened the hood to try and search from where it is coming from but it is just too darn hard to figure out.
I am hoping it is nothing related to my transmission. I may pull the fill plug on it this weekend and try to stick my finger inside to see if I am low on fluids and it is making a hum (but I highly doubt it because when I filled it up after drain i filled it too the top). I haven't experienced any burning of oil and use 5W-20 (Castrol GTX since day 1). I may switch fluids on my next change and use maybe a different brand and viscosity (maybe use standard Quaker state at 5W-30).
Again it isn't an engine vibration, rather just a hum or almost like a stinking wobble and then goes away for a few seconds. I say wobble kind of like you would hear a drive shaft on a truck that wasn't balance properly and was spinning without being centred with counter weights.

I had both front hub bearings go out on me recently and replaced them with a Moog and a Timken unit (2 weeks apart). After replacement, I still notice what sounds like dry bearing or gear noise at 35-38mph, starting at about 25. There could also be tire noise mixed in. I don't drive this car normally, so it's hard for me to figure if this is normal noise for this car. I know the tires and low sound deadening on a Prius makes it much noisier than other cars, but even so, I just want to make sure there is no well known issue with other components. When the car gets up to highway speeds, that noise is masked by regular road and engine noise and the overall noise level is about what you would expect for a car like this. The noise at low speed remains the same whether in straight line or in a turn, or with the engine in neutral.
noise in my front end. I know there is a lot of stuff going on there so let me try. Noise is more like a groan not a squeak, tick, not an engine noise or a brake noise. Applying the brakes or turning the wheels does not make a noise. Best way to describe it to me it is like a bad bearing type of noise. The noise is starting to get louder.
View 19 RepliesI devloped a noise in the right front wheel. I thought it was a tire going bad so I rotated the tires & still had the noise. I was told by shop it is a wheel bearing. If that is the problem is that a DIY repair ?
View 5 RepliesI replaced the belt tensioner. Today, after much prodding, I noticed the tensioner is rattling which is weird considering is only a year and some months old. The question is what can cause the tensioner to rattle? The belt is fine, is not cracked and it sits fine on the pulleys.
View 4 RepliesI needed to tighten the belt tensioner up, but couldn't find a DIY. So reaching out to see if this is normal? If not how do I tighten it up?
Here lately the car has been idling funny, kinda sounds like it has a cam or something, once I accelerate it smooths out fine. I thought it was a loose clamp on my intake to the turbo but once I got that clamped down correctly it still was idling this way.
First off I have a issue the Timing Belt Tensioner Stud / bolt that holds my tensioner on is stripped and came out with my tensioner. I don't want to risk putting it back into the engine because some one prior to owning my car stripped the nut that holds it in. Where I could get a new one of these bolts. I have a 2000 VW Golf GL with a 2.0l. I've searched high and low on parts sites and cannot figure out where to buy this item.
View 3 RepliesI've replaced the serpentine belt on a 06 Pontiac G6 (6cyl) and I noticed at idle the tensioner has a slight bounce to it... Is that normal? It goes away when you hit the gas. Apparently the tensioner was replaced less than a year ago
