Water Pump leaks and then stops

[CB900F2]

Hey guys.. Has anyone experience the situation where your water pump had a small leak from the pump's seeping hole but no further leaking?

I found a very small amount of coolant on the water pump pulley and it was crusted on the bottom of the pump near the seeping hole. I cleaned up the area and had no futher leaking since then, and it has been about 20 days now..

thanks guys..

P.S.. No mods to the pulleys, all OEM..

Its not uncommon that bit of crystalization can kinda slow or stop things for a little while but its going to start leaking again. Best to take it in while its still under warrenty than wait till it completely fails

[Sir A.Y. Atoyot]

Intermittent leaking is typical of water pumps. Just get it replaced - it won't really heal itself permanently:laugh:

Thanks guys

I will get the pump replaced under warrenty, guess now I will have to wait for it to leak a bit to show the dealer. Not sure if they will take my word on it

When i brought mine in the service writer just put on the paperwork customer states water pump is leaking.

End of the day i get a call my car is ready to be picked up and it has a new water pump.

They know its a very common problem with the car. All they have to do is just look at it with a flashlight. Of if it starts to get bad just look at the hood for pink lines.

Kinda pissed a newer car has this issue that may never go away without regular changing. Maybe should be part of the 30k mile service water pump replacement hah.

But at least its easy to do myself once warranty is over.

Little early for an 08 sedan to be needing a water pump,are you sure it wasnt a little splatter from the dealer toping up the radiator or maybe a bit of venting from the overflow tank..

[CB900F2]

It is the pump for sure.. and I only have approx 37000km.... not pleased with the situation with such low KM...

time for an electric i say. if i could find a good one i'd do it. had one on my camaro that got around 45k miles before i got rid of it, and as far as i know, the guy i sold it to still uses the same one. for 165 bux it was cheaper than factory, saved on power loss and i got better mileage with it.

im surprised with them being factory on stuff like bmw and mercedes that toyota and their 'fuel efficiency' claims havent done anything with them yet.

The LL coolant is a WP killer. BTW spell: warranty

[Lucas13]

My WP just gone with 56k!

Is one of those things that I never expected to happen to my Yaris Specially at that Mileage...? That sucks, but I’m pretty sure that staler will fix it under warranty.

Is there any other option of coolant that is compatible with the Yaris radiator and that is nice to the pump too?

[auxmike]

mine seems to have stopped leaking too now!
No more pink stuff shooting up onto the hood.....
Tempted to leave it be since it's seemed to have fixed itself ....

[severous01]

it will always leak again. fix it while it's on your schedule and not the pump's. cuz it's always gonna be that point when you have somewhere urgent to be.

[krusty]

the crystallization is not a water pump problem its the super long life crystallizing as far as Toyota is concerned it normal as long as the coolant level doesn't go down they do not want to replace the water pump.

[bronsin]

In the past typicially when a wp leaked a few drops it REALLY let go a short time later. It would be a catastrophic failure. These Yaris pumps seem to lose very little coolant when they leak. Then they stop. I would bet theres little or no discernable loss of coolant. If not under warranty I would be tempted to leave it be. But then if it crapped out it would probably be inconvient as could be.

Posted on other thread but the telltale signs were noticed on mine and a new one is on the way.

Lucas.....do a google on anything other than Toyota stuff before taking the plunge. I did and was surprised. Sticking with Toyota fluid.

i noticed a faint spray line on the underside of my hood, but it does not drip from beneath. just gonna keep an eye on it and watch my coolant level.

can anyone explain why or how my coolant only leaks when the engine is running? this is not normal, right?

[auxmike]

Coollant is under pressure and moving when engine is running.

[swidd]

How do I go about installing electric coolant pump if/when the wp gives up? Any DIY guides?

[brg88tx]

mine completely quit leaking too. coolant level in reservoir in near the full line.

maybe a little splash on the hood is not an indicator the water pump is out. does it just do this periodically to relieve pressure.

As far as I know it's a sealed system (except for the reservoir which has an overflow). if it's leaking, it is most likely that a seal has gone and liquid is getting out where it shouldn't. The water pump will probably still work, just not as effectively so it's not 'gone' but your seals are gone and it's probably a lot easier to replace the whole thing rather than just the seals.
if you kept running it with the leaking pump, then you're loosing pressure, loosing coolant and just not working as efficiently.

132,000km (82,000 miles) no water pump issues, no leaks, no spray on the hood.:headbang:

I have a 2003 echo, can noise from the engine come from faulty water pump?

I checked the pulley and it semms a bit 'loose', and my water deposit level goes down pretty fast :s

[BLH]

I don't do much driving.
My 2007 with 14,470 miles and exactly four years from delivery date.
Water pump failed with similar findings.
Dried coolant spray line on underside of hood and inside the water pump pulley.
In warranty replacement yesterday as it was part of the 60 month 60,000 mile warranty.

[auxmike]

I'm on my second pump. The original went at about 35k. The OEM replacement started leaking less than 2k after install. It "spits" some days, does'nt on others. I just check it and the coolant level frequently. Level's been pretty steady, does'nt go down. I'm not putting in another till it gets bad. Or I might pop in an AC Delco unit I bought recently around Nov. before the cold weather hits...

auxmike - Just curious as I'm guessing I'll run into this issue at some point too. Did you DIY and was it cramped getting the pump in and out? Doesn't appear to be whole lot of clearance in that area.

[Klink10]

Alt.---not Mike but having done it myself yes it is cramped. It's alot easier if you can get the pulley off and then remove the pump. I am glad I had changed over to the NST pulleys when it came time. By being able to remove the pulley you really don't need to mess with the motor mount as per the service manual instructions.

Yeah, I did DIY.
In order to get the old pump out I had to put a 4ft. pry bar between the engine and the frame side. Then I pulled real hard as I slid out the pump. It did put 2 dents in one of the A/C tubes though. Rested the bar on the center bolt of the crank pulley. I did this because I did'nt want to start lowering the engine and causing more problems...

Oh yes, removing the pulley first is a must. Did you pry at the engine sideways to get it off?

[Klink10]

Mike. No prying at all, once the pulley off and that bracket rotated it was a piece of cake.

Which bracket? Fill me in!:eyebulge:

[Klink10]

You know that little bracket affixed to the frame that holds the AC line. Just un-bolt from the frame and rotate it up so its out of the way. Leaves a clear path for withdraw of the pump.
