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.

I had to replace my water pump after driving with newly replaced Toyota Red antifreeze from the 8 year old Pink. I drove only two weeks and 1000 miles on it.
I believe that was just a coincidence. Some Camry's water pumps do not last even that long. Even if the coolant was not compatible with Toyota specification, it still could not destroy the pump seals in two weeks.
I have a 2011 ISF with 41k miles on it and yesterday I noticed the famous dried pink coolant below the water pump. I thought it only impacted previous years but apparently not. I'm going to drop it off tonight at the dealer since it is still under warranty. Doesn't look like the job has been done before according to Lexus service records.
View 3 Replies2004 Lexus rx 330 with 53000 miles, I took it to the dealer for 50,000 mile service when he requested me to change water pipe for coolant because he found heavy coolant residue under the water pump. My question is do I need to change timing belt also right now. when I called the mechanics some of them recommending me to do the timing belt also.
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 RepliesThis 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.
View 8 RepliesI noticed some "pink residue" while changing my oil this evening. Is this a coolant leak? I'm not sure what parts are pictured, but I'm guessing that is the water pump area since the pink residue is also inside a pulley.
I currently have 85K miles on my 2008 and purchased the extended warranty which pushes it out to 100K. QUESTION: If it is a coolant leak would this be covered under the extended "Platinum" warranty I purchased?
My 2006 Prius with 120k miles has coolant seeping around the water pump. I called around to get quotes on replacement cost, but one place said the thermostat should be replaced at the same time, while the other said it shouldn't. (BTW, I will have the belt replaced at the same time).
View 8 RepliesToday, I was greeted by a big red STOP! warning from my 2000 Passat 6 cylinder. The car drove fine last night. The coolant reservoir appears empty and has brown residue all over the inside. I notice for the first time that there is pink fluid on the floor -- I'm assuming this is the G12 coolant.
It's not a hot day, so I put in distilled water, turn up the heat and drive my Passat (trying to stay under 2k rpm) down to the dealer. They say that the coolant from the oil cooler leaked into the oil (and presumably, vice-versa).
I bought my 2008 JDM Prius a couple of weeks ago, at 84,500km. After a week, it started losing engine coolant. (Great start! Hope it's not a sign of things to come...) Fortunately, covered by a 3 month Dealer Warranty - hopefully. Yet to make the claim.
Anyway, went to the local Toyota Dealer to get some of the proper Toyota SSL (Super Long Life) Coolant to top it up. Got chatting with the Service Agent about Prius Service and what HSD Adjustments are possible (not many) and showed him my symptoms.
Actually 2 very similar questions about my Prius 2007.
1. My water pump was replaced by a dealer due to failure some half a year ago at 95,000 miles. Yesterday, after oil change (98,000), I was told it is recommended to replace engine coolant. Does this sound right? Don't they change coolant when replacing the pump?!
2. Identical question about HV pump. It was replaced at 80,000. Now they recommend do change the coolant for hybrid system. Don't they have to do it when replacing the pump?
I want to do everything necessary to maintain the car. But don't want to spend money for something that is not needed.
My 2004 just developed a coolant leak. The past couple times I've moved the car, there's been a small pink puddle under where the engine was. The leak seems to be coming from a weep hole positioned between the two bolts of the lower engine mount. The hole is circled in red in both pics.
View 1 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 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 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.
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.
View 14 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 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 was driving my 2005 RX 330 (138k miles) North on I-75 through Atlanta in rush hour traffic when the car completely died in the left hand lane w/ no shoulder. GDOT stopped six lanes of traffic to push us up and over a couple of hundred yards to a right shoulder. It was determined that due to a coolant leak from the water pump the timing belt malfunctioned and shredded.
I had heard that the water pump should be replaced during the 90k maintenance when the timing belt is changed, but my water pump was not replaced according to my maintenance records. I understand from reading a couple of posts that this isn't always required but that they do check the water pump. Is this correct? And if so should they have noticed that there was a potential problem?
