The water pump on my 04 with 132k miles is rattling / wobbling (but surprisingly, not leaking). So I am going to replace the water pump, serpentine belt, and thermostat. The idler pulley seemed fine so I am wondering if I should replace it. What is the failure mode on the idler pulley and how will I know it is going bad without having to check it? Or should I just go ahead and replace it?
View 9 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 RepliesMy sister's 2010 corolla with 80k has a rattling. She sent a video. The oil level is fine. She had a belt squeak previously that she had fixed. My concern is a bad water pump. Is there a service bulletin on this that we can confirm?
View 17 RepliesI had the doors open while unloading the car this morning and noticed that the brake booster pump just kept running and running and running, plus I can hear a strange, hollow rattling sound somewhere under the car that coincides with the pump. When I say it runs "constantly," I really mean that it runs for 10 seconds (with the rattle), stops for about 5 seconds (silence), runs and rattles for ten seconds again, stops for another five, and just keeps on going for as long as I care to sit there with the door open.
View 15 RepliesI 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.
View 19 RepliesI 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 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 RepliesLooks like my mystery growling noise at idle is the WP going bad. Not leaking but making a racket at idle.
View 19 RepliesI've got a grinding noise coming from near my water pump. replaced the serpentine belt w no luck. it's got 212,000 miles on it so I'm guessing the water pump is going bad.
View 14 RepliesToyota dealer said computer indicated the water pump and belt needed replacing. We decided to do the replacement ourself. Now the light comes on which indicates car is running hot. We did replace the coolant. The 2005 Toyota Prius never ran hot before the replacement, What did we do wrong?
View 3 RepliesI just joined this great forum and having a tough time finding a solution for Water Pump and Timing Cover Leaks.
2007 Prius Pkg 6
111k miles
Bought the car used from a dealer (non toyota) and doubt that the 90k service was done
Issues found by dealer (when I took it in for the steering shaft recall):
-Replace water pump (Found coolant leak) (for the gas engine)
-Reseal timing cover (Found engine oil seep)
2 weeks ago I filled my coolant as I saw it was a tiny bit low, but since then I have not seen the coolant levels drop. The Dealer is quoting me an absurd amount of money and I for one cannot afford that.
My 2005 Prius sounds louder to me than normal. The car has 117,000 miles on it and is in great condition. Anyways I can hear, maybe, on the gas engine what sounds like a bad water pump or tension pulley, not sure though? I checked the water pump area and there is no visible signs of a leak or dried pink coolant. If the water pump is indeed bad what can I expect at the Toyota dealership cost wise?
View 18 RepliesI have worked on several minor to moderate engine issues over the years with various brand cars so I was thinking about replacing my leaking main water pump (not the Hybrid pump).
View 9 RepliesI have a 2008 Prius T6 that I took in for routine oil change at Big-O tires. They called and said water pump was leaking badly.
Pump replaced 2 hours later, but they cannot "burp" car because it won't start. The hybrid battery is apparently too low (1 purple bar) and after repeated attempts it's dead (one vertical bar on display). I've never seen this happen before... I've seen the car battery die (after leaving lights on) but the hybrid battery has never gone low.
Big-O calls and says,
(1) We've replaced pump before and never seen this happen
(2) We called Toyota and there is only one high-voltage charger in the region... we don't know where
(3) Toyota said nothing is wrong with the car, it just needs a charge
(4) Toyota said we did nothing wrong
Recently blew the belt that runs the water pump, etc while on a vacation. Had to leave the car at a small mechanic in Winthrop, WA. He replaced the Water pump which had gone bad and the belt that shredded. The car ran beautifully for a week. Now there is this constant rattling sound coming from the water pump area. the link is a video with the sound. The sound will quicken as you accelerate. At cold start up it is usually not present then starts a couple of minutes in.

View 2 RepliesI took my 78K '07 Prius into dealer for the recalls, one of which was the electric water pump.
After picking up my car pulling out of the parking lot it started gurgling and hearing liquid sloshing around, I drove it straight back to dealer and they told me this new noise was from nothing they had done and must be a convenience. They believe its the ICE water pump as they can go bad at any time. I'm frustrated as I feel they had sabotaged my Prius and want the $400 to do the replacement.
On my 05 Prius (65K miles) I recently had my local Toyota dealer replace both the inverter water pump (for free per recall) and main engine water pump (~$500 based on their recommendation because of some coolant leakage). 1 week later, I got the P1121 code coming off and on intermittently.
My dealer says that the work they did is not related to P1121.
The gist is that my 2006 Prius would not start, even with an attempted jump, and now the dealer (Keany Mesa Toyota in San Diego) says the total cost of repair will be $2400 for a new junction box relay and water pump ($800/$2400). I am stunned at the cost and am questioning the need for both jbr and wp -- but apparently, wp is leaking. About a year ago, the expensive battery was replaced, luckily under warranty , so no cost. Don't know if jbr, wp and battery failures are related, typical repairs or we just have a lemon or getting ripped off. is the water pump recall from years ago relevant here? Should we get a competing bid from a non-dealer/Prius expert (is there one in SD, a search of Prius chat found 1 recommendation but it was rather weak), or just get the damn work done and have a stiff drink to deal with it, or maybe it is time to get a new car - Prius or other (what's the chance the dealer give us a good trade-in deal?)
View 17 RepliesI have a small problem, the dealer that serviced my car just told me that my water pump was leaking and I was low on coolant. I can't remember when was the last time I checked the coolant level but when the dealer top off the coolant, he nearly used the entire bottle. Needless to say, I believe the radiator was pretty low on coolant.
Now I've never noticed a high temperature warning lamp or ever broken down. Today at 125,000 miles, I went to change my spark plugs. The 1st plug to the far left as you are facing the car has oil in the spark plug. This is freaking me out, could my engine be damaged from the low 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.
