Camry :: V6 Water Pump Leaking Through Its Pulley Shaft
Sep 27, 2015
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.

A little less than a year ago I decided to change the timing belt & water pump on my then 61k miles '05 V8. I bought the BlauParts timing belt kit and rented the tools from them also. The install went without a hitch, the old water pump gasket came off nice and clean and I installed the new water pump gasket without any RTV as per the instructions.
A couple of weeks ago the Phaeton hit 65k miles so I did an oil change and while I had the belly pan off I noticed a small whitish pink spot on the belly pan, right below the crankshaft pulley. Looking closer I found coolant traces that came from the water pump area. I cleaned it all up and decided to drive it for a few weeks to see if it's an actual ongoing leak or if that was maybe just an old leak that might have happened just after the install. Unfortunately it's an actual leak ..
First I thought maybe it's leaking out at the gasket but closer investigation shows that the leak is actually right below the pulley at the bottom of what looks like a freeze plug at the front of the water pump. Is this a common area for a leak with this type of water pump? It's only been installed for 11 months and 4,500 miles. Btw, the pump in the kit is a Saleri model GD42107.
I'm really bummed about this because it's a lot of work to swap a water pump out and I'd hate going thru all that work again (and having to rent the tools again). Question is, can I swap the water pump out without putting the front bumper into the service position? From what I recall the only clearance issue might be finding a puller that is short enough to pop off the camshaft sprockets with the radiator that close.
Here are a few photos from when I found the leak:
This was after a 200 mile trip, fresh coolant:
This is were the leak is coming from:

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 .....

my 2007 Camry LE I4 and I got an oil change at the dealer today. He tried to tell me my water pump was leaking and needed replacement.
Offered me a deal of "%50 off the price for $500" which I think is ridiculous. Took it to a family friend that is a mechanic and he said $266 to replace the whole thing.
Dealer said they would do a price match but I'm not sure what to do.
They said it would make it to Tennessee and back because it's in its infant stage.
My question is, when I refilled my low antifreeze, I accidentally overfilled a lot past the line. Would this have anything to do with this issue?

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.

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.

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.

I 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.

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.

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.

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.

Need 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.

2010, 5.4L... Noticed a small oil spot under the truck this morning. Took it into the shop after work, we lifted it up, and ran it for 15 min to see where the leak was coming from, and the truck did not leak a drop... until we turned it off. The oil would slowly leak near the power steering pump pulley. But only when the engine was not running ...

I learned today there are at least two water pumps in my 2006 Prius, and that one of them is leaking. I had the recall done for the electric motor water pump in November. Now, during my scheduled maintenance, they tell me my second water pump has been leaking (slowly). My car has 132,000 miles.

I just got back from the dealer and was told my water pump was leaking. I was told it was a small leak and that it could only be seen by lifting the car. I opened the hood and noticed some pink crusty looking thing on what i believed to be the water pump. I took some pictures of the water pump, the radiator and overflow level. If you look closely you can see some of the pink crusty stuff around the pump. I poked it with a pencil and it broke apart pretty easy.
First of all if that pink crusty stuff is anything i should worry about? Also if the levels of the fluid in the radiator/overflow tank are good? Is there another sure way i can tell that i even have a water pump leak? I searched around the forum and it looks like the hardest part about replacing the water pump is getting the air out of the system and that the dealer quote is a rip-off.

My ICE failed to start on a wooded forest road -- after the car had sat under a fir tree for a day or three it ended up starting and all the warning lights went away. I ended up taking it to the dealer though and while they replaced a leaking water pump, never found any cause for the ICE failure.

I replaced my timing belt, tensioner and water pump last weekend because I noticed I was leaking coolant from the water pump. The other day I popped my hood after driving and notice the reservoir bubbling a little bit because it sounded like the coolant was boiling and the line coming into the top of the reservoir felt hotter than normal. I opened the cap slowly and never heard any pressure release. I figured it was air in the line somewhere so I tried to work the air out. It sounded like the air came out and I took it for a drive and I finally heard pressure release after 3 different attempts. I opened the cap later when it was cool and noticed that the coolant was still at the original level.
Then the next day I was driving and came to a stop and noticed white smoke coming out when I gave it gas. It still drove fine though. I pulled over and opened the cap slowly but didn't hear any pressure release. I put in a little bit of radiator sealant and it seemed to do the trick.
The car has never overheated and there's no oil in the coolant or coolant in the oil. The heat also seems to be working correctly and my fans come.

I have a 2008 sante fe 3.3 the water pump is leaking. I have the replacement pump, however I'm not sure how it is designed to come out due to clearance issues. It's easy enough to unbolt a pull loose, however clearance between the car frame and pulley is 1/4 inch. How does it come out of the compartment?

I have an 2002 which I bought new. It's got low millage, just over 92,000. I took it into the dealer for a free state inspection and was told that the water pump is leaking. Given the age I'm not too surprised although I don't know what the reliability is like on that part.
I want to verify myself that the water pump is actually leaking before having it replaced but don't know where it is or what to look for. Googling hasn't been too useful - I get lots of hits about the inverter pump, not the water pump.
I have not seen any signs of leaking on the ground under the car. There was no mention of the water pump leaking when I took it to the dealer at 90,000 for an oil change, with my original service advisor.
Is the water pump something that I can fairly easily inspect? Where do I find it and what do I look for?

My water pump housing is leaking. My 09 is well out of warranty but that's not really my question. I would like to know what you did when you replaced your water pump. did you upgrade to a metal impeller pump such as the GEBA brand?

This is weird, I just replaced my ICE water pump 2 months ago and now upon inspection, I notice there is pink seepage coming out of the pump again. Although it's a very very slight amount, but being the fluid is pink, I can see the stuff coming out again.
