Ford Excursion :: Idler Pulley To The Right Of Alternator On V10


Mar 20, 2010

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?

Ford F-150 - 1997-2003 :: Replacing Idler Pulley?

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.

Ford F-150 (2004-2008) :: Top Right Idler Pulley Bolt Broken

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.

Ford Ranger / B-Series :: Squeak When Running / Idler Pulley For The Timing Belt

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.

Santa FE SM (2001-06) :: Idler Tensioner Pulley Seized

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?

Sonata NF (2006-10) :: Idler Pulley Bearing Has Become Quite Noisy

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.

Lexus RX 2004-09 :: Chirping Noise Coming From Belt Tensioner Or Idler Pulley

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 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.

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?

Camry :: 2006 - Loud Noise Coming From Idler Pulley On Cold Startups When Put It In Gear

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?

Santa Fe (CM - 2007-12) :: 2011 - Alternator Pulley Loose

My sister has a 2011 Santa Fe that was making some noise so she had it looked at at a local Monroe, which then said that the Alternator Pulley is loose. I haven't had the chance to look at the car myself, but in this case, would it be possible to replace just the pulley? Or will I have to replace the whole alternator?

The guys from Monroe said the alternator will have to be replaced as a whole. But from pictures I'm seeing online, it looks like the pulley is held by a 6-point nut, with a torx screw in between to counter hold the rotation. I can also see some listings on eBay for just the pulley. So I'm thinking I could start off by tightening the nut or replace the pulley if it's dented or off shape. Will I have to replace the whole alternator?

Ford Excursion :: Alternator Gone - Fused Somewhere?

Coming home tonight I drove the last 10 minutes in total darkness with only enough power apparently to keep fuel pump running. I just replaced the alternator two weeks ago but it seems to have gone again. At the alternator I have 11.3v at idle. There is a two wire plug plus the power cable. One of the wires has constant on power. The other has nothing. It is not switched even though I think it is supposed to be. Is it fused somewhere?

Ford Excursion :: Change Out Alternator To High Output?

I decided to change out my alternator to a high output. After researching I've decided to go with a DC Power...I'm planning more lights and a power inverter. Any recommendation on which one? I don't care what it cost just don't want to over do it, can too many amps hurt anything? Also, on my previous EX I did the big 3 upgrade. Is it the same on a 2 battery setup?
