View 6 RepliesMy 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?
View 12 RepliesDoing 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.
View 1 RepliesI 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.
View 1 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 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?
View 3 RepliesI have a 2004 accord exl (4 cyl) and it's making a whining noise. At 1st I thought it was the serpentine belt but then listen closer and it's seems like it's the water pump pulley (top pulley). I sprayed it with silicon oil and it minimized it but still comes back some with driving. The car has 110.5K miles on it. Kind of early for the water pump to go??? The belt is original and doesn't seem too bad. so I guess the bearings are going and it's time to change the belt and the water pump.
View 10 RepliesSo I have had my 2005 Prius for over a year now. I love my car but after 7 months it made a whining noise coming from by the pulley. When I would accelerate the noise would get worse. Engine light came on tested and said loss of power. The car would not go up large hills it was gutless. So I parked it. I recently just replaced the pulley and now the noise is gone. I have been driving it short distances and at about 30 miles per hour the car would sputter and hesitate. I would let off the gas and push down on gas pedal lighter and it would go fine.
View 19 RepliesMy 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?
An idler pulley on my 2002 F-150 seized and snapped the serpentine belt. The pulley is below and to the left of the belt tensioner. The pulley doesn't have a bolt but a hole that looks like an allen wrench would fit it. I couldn't find an allen wrench to fit it. Called AutoZone and they have a pulley removal tool in three sizes. What size wrench would fit the idler pulley? I want to make sure I get the correct size tool so as not to screw up the pulley when I start pulling on it.

View 5 RepliesIn 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.
I need to replace the bearing on my Idler pulleys, both smooth and grooved. I also want to replace the bearing on the tensioner pulley. What are the part numbers and the best place to order them from?

View 6 RepliesI 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?
View 6 RepliesThe 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.
View 11 Replies2002 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've been noticing more and more lately that while my trucks in 1st or maybe 2nd gear, say, slowly coasting around a parking lot for example, there's a whining noise coming from either the rearend or the tranny (cant tell which). It gets louder and more high pitched as I move faster then disappears as soon as the truck shifts gears..
Is this something serious like my transmission on its way out? From what I gather a lot of people seem to have a similar thing going on.. From what I can remember my truck has done this since I bought it, but lately (and maybe its just me) I seem to notice it more like maybe its getting louder..
I have 2005 F150 XLT 5.4 litre engine and my battery light comes on after letting the truck run on idle or sometimes driving.
Last Saturday went out drove it heater on and radio on I smelled something coming from the heater kinda like burning wire smell didn't think anything of it no smoke from heater (indicating the core was bad) no lights on the cluster nothing; went into the bank let it run came back out my battery light on. Drove it home and while driving the light goes off.
Opened the hood and the smell was coming from the alternator. So I turned the truck off. Let it sit for an hour or so then I took my voltmeter to see if the battery was good. The battery was 12.4v with engine off. Checked my battery connection for corrosion or loose connections everything was tight there was some dust on the battery terminals so I brushed them off. I checked the battery cable that goes from positive to the alternator where it connects to the alternator with that nut it was good, clean and tight.
So I started the engine up and I can hear a whining noise from one of the pulleys. Let it idle for 2 minutes no battery light so I put my voltmeter on the battery it read 13.8v, so I turned on the A/C, head lights, radio and the heater tried again the voltage dropped down to 11.9v then the battery light came back on. Also through all this my battery gauge in the cluster always stays a half way mark doesn't drop or go high. Next with the engine turned off I took the belt off checked the pulleys the idler pulleys seem fine and the belt doesn't show any glazing but the alternator was hot almost like touching a hot exhaust manifold.
So for the last 3 days I have been trying to come up with how to resolve this issue obviously it could be the alternator going bad but the battery has never lost a charge yet I let the truck sit for these past 3 days and today I started the truck and it started right up I don't see any dimming lights except it has a whining noise and the battery light didn't come on immediately I let it run for 5-10 minutes before it came on; I even drove it around the block and the whining noise gets louder every time I step on the gas. To me it's either I need new alternator, tension pulley is bad or the idler pulleys are bad but they turn fine.
'05 F150 5.4 Sounds like a whining noise from the front end when turning to the right or going straight. Goes away on left turns. Thought it was tire whine but put originals back on and got same thing. 13.5x35 verses 275 Truck has a Fabtech 6" lift. Right CV axle seems tight, rotor assembly replace 2k miles ago. Any other option before going into front diff?
