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.
View 6 RepliesI 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 10 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 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 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.
Changing serpentine belt? I have to but was looking for some pointers or tips. I assume the fan shroud must come off?
View 14 RepliesThere are two bosses on back of hpop cover that have bolts holding heat shroud for the exhaust. How difficult are these to remove? The drivers side looks fairly accessible, but passenger side I am not too sure of. I will be back to disassembling everything in a couple of days, and just getting a heads up on it.
View 5 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 2 RepliesI 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.
View 6 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 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 4 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.
07 f250 I just replaced the power steering pump. I put the serpentine belt back on and when I started my truck I now have a squeaking noise. It's driving me nuts and the more I push the pedal it gets alil louder. Now before I did the ps pump I did hear a little noise like of bearings squeaking when I put my ear to grill.... I put the old ps pump pulley on the new pump but I don't think that is it because it is pressed on. Would it be a bad idler/tension pully? Is it just a coincidence after I do ps pump that it now decides to squeak?
View 10 RepliesNeed to know the thread pitch and diameter for the water pump pulley bolts? The previous owner of the engine I bought clearly didn't know how to get the fan off as the pulley and plastic fan are both loose so I cannot loosen large nut.
View 1 RepliesOk 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 am reviewing the ford assembly instructions before I put my engine back together and noted that it indicates that the balancer bolts are torque to yield. I thought it odd but is it really necessary to replace these? Is it done in practice?
View 1 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 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 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.
