Camry :: V6 Water Pump Leaking Through Its Pulley Shaft

I 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.

Camry :: Toyota 2008 - Misaligned Water Pump Pulley?

I 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 .....

Prius (2004-09) :: Rattling Noise Near Water Pump / Pulley

My 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.

Ford F-150 - 1997-2003 :: Water Pump Pulley Shims

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.

Mustang :: Replaced Water Pump / Thermostat / Underdrive Pulley But Still Overheats?

My 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.

Prius (2004-09) :: Pink Coolant Residue On Inside Of ICE Water Pump Pulley

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.

Lexus SC430 :: Brake Noise / Squeal During Initial Deceleration

So, I have Stoptech rotors and brakes, and it squeals when (a) it's warm after a few minutes of driving and (2) only when I initiate braking softly to slow down, but disappears after braking firmly to stop. Brake pads have about 80% left on them.

Lexus SC430 :: Squeal From Brake Fluid Reservoir Area

Just fired up my 2002 SC430 (115k miles) for the first time this year, so it's stood for over six months. Connected fresh battery, checked all fluid levels etc. Runs fine and purrs like a kitty BUT I'm getting a loud intermittent squeal (like you might get with a sticky pump or a slipping belt). Almost like a loud "meow" in duration & tone. So loud it can be heard from 20' away. Sometimes once per minute or two, sometime several times in a row then silence for a few minutes.

This is from the area where the Brake Fluid Reservoir is (on Right Hand Drive SC430 this is right by the Windscreen on the left hand side of the engine bay as you look at it from the front of the car (may be reversed on Left Hand drive models). Directly in front of the Steering Wheel.

(ABS) check light is on. Also "VSC" & "VSC off" check lights on (probably related to ABS being in check and VSC button does nothing to clear those lights). Also getting the buzzer alarm from the dash. Pumping the brake pedal and driving the car forward/back 10' several times on the driveway doesn't clear this.

Now, this may be that the Brake Pads have bound to the Discs (Rotors to you left-pondians). I may need to pop the wheels off and free up the Pads in that case.

Lexus ES 2007-12 :: 2008 - Water Pump Failed No Warning - Engine Fried?

I was on my way to TN for vacation. Car 2008 ES 350 with 49,000 miles had just been to dealer for new battery 1 week before. Driving on I95 and check engine light and 2 other lights came on and smoke came out of hood but temp gage stayed at C even though car was overheating.

Got off hwy and discovered there was no coolant. Bought correct coolant and put it in. Got back on hwy and car started to smoke so pulled off and fortunately car died at end of ramp rather than in the middle of interstate. Had to be towed 50 miles to Lexus dealer who told me that water pump failed and heat destroyed engine. I'm away from home in shock without a car. How a 2008 with only 49,000 miles impeccably maintained could all of a sudden overheat without warning.

Lexus SC430 :: Slight Squeal From Left Rear Brake When In Reverse

I have a slight squeal from the left rear brake when in reverse. Doesn't do it all time and never when roads are wet. I disassembled the caliper and all looks good. I replaced the pads about a year ago and the noise just recently started, so its hard to blame that. I did not use the brake anti-noise lube......but I never have.

Lexus SC430 :: Driver Side Brake Has A Loud Pitched Squeal

I replaced my brake pads and rotors and now the driver's side brake has a loud pitched squeal. It doesn't squeal all the time and if I let up on the brakes and apply them it goes away.

I think maybe one piston is hung up.

How do you free up a stuck piston in the caliper piston?

Or could there be another reason for the squeal.

I installed Callahan slotted rotors and ceramic pads on all 4-wheels.

Ford F-150 (2004-2008) :: Squeal That Sounds Like A Bad Pulley?

Its actually on a 2008 E350 with a 5.4 but figured its all the same. There is a squeal that sounds like a bad pulley but its coming from the flexplate or torque converter. I have taken the belt off to verify. I dont see anything psychically wrong like cracks, bends or anything touching. The little I can find on this subject I would say flexplate has a crack somewhere. Transmission shop also can not figure it out. I just want assurance before pulling the transmission in this beast.

Here is a video : [URL]......

Lexus SC430 :: Water At The Front Of The Trunk - No Leakage

I am getting water at the very front of the trunk, nearest the passenger compartment. Might be the drains in that vicinity that might be plugged causing an overflow there .Rest of the trunk is dry. The only wet area is immediately underneath the pull-out "shade" thing that has to be in place for the top to operate. Some indication that the water is coming from above that, since it is wet also.

Ford Escape / Hybrid :: Water Pump Belt Squeaks For 15 - 20 Seconds After Cold Start

2 questions regarding my 2005 Mariner 3.0L, as follows:

1. After a cold start (in the garage, so not freezing cold) the water pump belt - not the serpentine belt - squeaks for 15 - 20 seconds; ambient temperature doesn't matter. I had put a new belt on about a year ago, then this began 6 or so months later. Thinking I may have a defective belt, I replaced it again about 3 months ago, but the squeaking has continued - starting immediately after the replacement. My analysis is that the water pump bearing is going south. I've noticed that it is taking a little longer for the squeak to go away in the past few weeks, so it's probably getting worse, altho no leaks at this point. So the question is, so any other reason this is happening?

2. Assuming I do need to replace the WP, I bought a new one from the local parts house. I have a shop manual for the car, which tells me to remove the thermostat housing, hose connection to the WP, etc., and then remove the WP by removing just 3 bolts. However, the replacement part is just the front of the housing with the impeller and pulley included, so there are a half-dozen or so bolts that hold this new part onto the WP housing. So, doing this change-out? Will the front of the WP housing come off by itself without disconnecting the hose, etc., or do I first have to remove the whole WP and then take it apart to replace the impeller and front cover? I can't really tell from the pic in the shop manual, and it doesn't address dis-assembly of the WP.

Also, I'd like to just remove the belt w/o cutting it and having to buy a new one. Can I do this by just loosening the WP bolts? (I know how to re-install, obviously.)
