Water Pump leaks and then stops - Page 2 - Toyota Yaris Forums

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

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.

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

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.

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 · 05-05-2011, 06:39 PM

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 · 05-08-2011, 09:05 PM

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

Which bracket? Fill me in!

Klink10 · 05-09-2011, 09:14 AM

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.
