I 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 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.
View 4 RepliesMy wife calls me yesterday and said she could hear a rattling noise from the engine area, but no other issues presented themselves. Later, I checked the engine compartment for the noise with the engine on and found that the noise was coming from the area of the engine water pump/idler pulley but i couldn't really narrow it much closer. The noise honestly sounds like bearings about to go out. I did see that behind the water pump pulley there was a small buildup of corrosion on the water pump, but no apparent leaks or wetness. The car has the original water pump and idler pulley with 140k. I plan on replacing the water pump, idler pulley and thermostat in the morning. Or is this overkill? I don't want to lose the engine nor do I want my wife to get stranded anywhere.
View 9 RepliesI get a small "squeal" from the engine usually only when it's cold out, and have narrowed it down to the water pump pulley (2nd pulley down from the top). I put a drop or two of WD-40 on the "rod" that runs through the pulley and it stops. I know not to put anything on the belt to avoid contamination but it seems to me that it's the metal bolt that keeps the pulley in place. I stopped by an O'Reilly and had the tech have a look because I was going to try a more viscous grease. He thinks that it's either the pump is starting to fail or that the pulley could have moved out of place. He said I should remove the belt and tug on the pulley.
If it moves then it's loose and needs to be lubed and tightened. If it doesn't then it's a water pump replacement. What do you all think? I don't want to drop a ton of money as it truly only squeals when it's cold, and unfortunately I'm thinking Chicago's gonna have a cold one this year even though after the engine heats up it's goes away. If you have a guess to the problem, what do you think replacement will run me. I'm only at 30,000 miles, and has been garaged until recently so I don't think it's a belt change or pump failure yet.

View 6 RepliesI was hearing some sounds from my engine and opened up the timing covers to determine where the sound was coming from. It sounds exactly like the Sienna with the same 3MZ engine in this video: YouTube ....
While I didn't find the source of the noise, I did find that my water-pump is leaking. My question is, is this water-pump leaking bad enough to be replaced? I do not notice any coolant loss and never had the need to top up.
It appears from this last photo that the pump is leaking through its pulley shaft and not at the interface with the engine:
The timing belt and water-pump were changed 3 years ago with the Gates timing belt kit from RockAuto. The pump at the time didn't look that great quality in its casting compared to an Aisin pump.
I could not feel any play or hear any abnormal sounds from the pump while it was running with the timing covers off.
This is on my 2005 Lexus ES330 with the 3MZ-FE 3.3L V6 engine, same motor as the Gen 5 Camry SE V6.
How to remove the water pump pulley on a 2003 W8? I removed the 4 bolts but I don't want to go crazy and end up ruining it.
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 12 RepliesI have a 2008 Toyota Camry, 4-Cylinder w/ 55,000 miles on it.
Yesterday, when I started the engine I heard a rattling noise. Opening it up and looking inside, it seemed to be coming from the area of the serpentine belt. Looking closer, I saw that the pulley appeared to be wobbling slightly, although it didn't feel loose to the touch.
As I'm out of town on a roadtrip and needed to try to get home, I decided to try to drive it anyway. Aside from the noise itself, the car ran fine - the engine temperature stayed normal, which I kept an eye on closely.
After a bit over 50 miles of this, however, the serpentine belt got thrown off. With my engine temperature rising, alternator not functioning and power steering cut out, I pulled over immediately and shut off the car.
Looking more closely at the water pump pulley, I could see that it was clearly tilted in its alignment in comparison to the other pulleys along the belt's route. This explains the wobbling I saw. Clearly that needs to be repaired, lest it throw off the serpentine belt again.
So, this brings me to my questions here.
Given that the water pump itself seemed to be functioning fine during the drive until the belt got thrown, is it possible that just the pulley itself is broken? Or that it's misaligned?
If so, is it possible to replace / realign the pulley without having a mechanic tear the car apart to get the water pump out?
If these aren't the issue, is it possible that the water pump itself is just misaligned as opposed to broken? If so, can it be realigned without buying a new one?
I'm basically trying to assess
* what exactly is the problem
* whether it is something I can fix myself without a mechanit
* whether I'll need parts and what those parts would be
* how many hours of service I should expect to have to fund if I can't do it myself
Here's a picture of how it looks right now .....
Is it common to have to shim the water pump pulley? I don't know why but mine seems to have moved back a fraction of an inch. I loosen the belt tension and slide the belt back and as soon as I start the motor, the belt slides forward again. And as I rev the motor, the belt moves even further out onto the edge of the water pump pulley and starts to squeal. All other pulleys are aligned and the belt spins fine on them. I thought about buying a shim kit, but I ordered a new Motorcraft water pump since I have 154k miles on my truck.
View 7 RepliesMy son has a Mustang GT 5.0 that is overheating. I replaced the radiator with a heavy duty 3 core radiator. It had underdrive pulleys so I replaced them with stock pulleys. I put dual electric fans on it. I flushed the block and put a new thermostat and replaced all the hoses (made sure the bottom radiator hose had wire in it so it wouldn't collapse). I put a new water pump and drive belt but it still overheats when sitting in traffic and overheats when driving with the A/C on.
View 14 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?
On the 06 Prius I have been working on, I noticed a light build up of pink coolant residue on the inside of the ICE water pump pulley. I assumed that this was due to a coolant leak from the weep hole, which points to an impending water pump failure.
View 16 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 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 RepliesAn 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 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 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.
