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?
View 2 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.
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?

Also, if the above items will fix the chirp, which brand would be best?

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.
View 2 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 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 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 .....
View 6 RepliesI 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 RepliesHow to replace the belt tensioner. It's not putting out enough tension when the engine is cold. So, the belt makes chirping noise for couple of minutes idling when cold with AC on.
I had the AC inspected and everything checks out according to my mechanic.
He believes that the issue is with the tensioner since I had recently had replaced the serpentine belt.
I had my timing chain tensioner replaced. When they do this do they touch the serpentine belt tensioner? 1000 miles after the timing replaced, my serpentine belt shredded and they say I need a new serpentine belt tensioner. Does this sound correct?
View 3 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.
So my mk6 developed what initially sounded initially like a bad serpentine belt tensioner. Only under anything more than load, and sounded like a bird chattering under the hood. Got outside today, fired car up, watched tensioner and it sat there steady as a rail. The noise is coming from the opposite side of the engine. Not really mechanical/metallic at all and tracks under load with the RPMs. Why i initially thought what i did. Not I'm sort of baffled.
View 3 RepliesI installed a new serpentine belt tensioner into my 1994 Chevy Suburban C1500. It vibrated as much as the old one did, so I assumed that a bit of vibration is normal and forgot about it. Well, after recently looking at some instructional videos, I am now under the impression that any vibration in the tensioner is bad. Here is what is going on -- [UrL] .... Is it OK or should I get another new tensioner?
View 4 RepliesI was wondering because serpentine belt is a big thing for 05 corolla since everything runs on it. I also had a 94 camry which had a alternator connected to a belt. and if i wanted to tighten up that belt i would just loosen the alternator and pull it. Is there a way to tighten up serpentine belt in my 05 corolla in the same way?.
View 1 RepliesEver hear of a crank pulley failure? Mine did and took out the serpentine belt. I have 63,000 miles on the 07 and it was a big shock to see the pulley in two parts.
View 5 RepliesThe nut that holds the pulley in place on the alternator has fallen off, causing the pulley to become loose and now the serpentine belt will not stay on. What is the size and thread type for the nut that I need to replace?
Alternator Pulley Nut for 2004 Camry 4cyl
Been trying to isolate my noisy serpentine belt. Had the belt off and spun everything, only thing I found that made any noise was the alternator. It had a nice churp like a bearing was on its way out in it. So I replaced that figuring my squeak was going to go away. No such luck. Listening to it again while it was idling, I crawled underneath. Almost seems like the churping noise is coming from the Crank Pulley. Is there a bearing on this pulley that goes bad?

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 changed belts on other cars just never a Lexs. how hard is it to do on or trucks?
