DIY waterpump RnR

[kou]

this was from before the hack just thought i would put it up again.
1.let the car cool down.
2.disconnect battery.
3.disconnect plug and wire from alternator,lossen two bolts on alternator so you can remove belt.
4.remove 10mm bolt from bracket holding ac hose and slide bracket back.
5.remove two bolts from alternator and take it out of the car.
6.remove waterpump pulley three 10mm bolts and remove pulley from car.
7.remove the bolts from the waterpump.
8.get a jack with a some wood to support the motor as you will need to remove the bolts from the side mount and drop the motor to remove the waterpump from the car.
9.put new waterpump on and do all this in reverse.
10.fill up coolant.

Great post... How many miles/km on the car when the pump went?

[PetersRedYaris]

On Scionlife I have read about quite a few water pumps failing early. Same motor, same pump? Probably just a freak thing...

Edit- Well what do you know, 59,000 miles and my pump has some crust below the weep hole. These water pump failures seem to getting more and more common.

Great post... How many miles/km on the car when the pump went?

only 15,000 miles but i think it was my fault for tighetening the belt to much when installing NST pulley set.

[ztrack157]

You have coolant all over the place. I just took my hood off because I was fiddling around with something and sure enough I have coolant on the under side of the hood. I have nowhere the amount you did and there was none on the pulley or in the vicinity. Either way the bitch is being changed out next week.

[CB900F2]

ztrack.. Did you also install a NST pulley and possibly over tighten the pulley belt?

What's the deal with water pumps failing on NST pulley equiped engines? I don't think mine was affected by the pulley as the WP bearing noise started just a few miles post the NST installation and the antifreeze "crust" looked like it had been there awhile, though I didn't see it when installing the pulley.

My belts are definitely not to tight as I like them on the loose side. So long as they don't squeel, they're tight enough.

[kou]

i think mine was bad before the nst pulleys.maybe just the way the belt is tensioned from the factory.

[ztrack157]

I have NST as well. And in the last 2,000 miles I heard a noise I knew shouldn't be coming from the engine bay. It was the water pump. I don't know what is considered to tight I can still wiggle the belt. And I had thought it was to tight so i loosened it slightly and then spun the belt so it wasn't to tight after installation.

[auxmike]

THe pump's not covered by the warr. guys?
Why did'nt you just let the dealer shoulder the labor/cost?
Don't you get 5/60,000 on the drivetrain???

[ztrack157]

Yes we have that but with NSt they can say we over tightened the belt. Thus no warranty.

[BLAZINBLUEVITZ]

this problem isn't specific to nst equipped cars so don't start assuming its gonna happen to you if you have or are gonna buy. my buddy who's a toyota mechanic says water pumps and yari are starting to become a regular thing at his shop.....

[nemelek]

How much does a water pump cost? Did you get from Toyota or some place else like Auto Zone or NAPA?

[auxmike]

my buddy who's a toyota mechanic says water pumps and yari are starting to become a regular thing at his shop.....

Wonderful.:mad:
Did he give you any idea on about what milage the pumps go?
That's unacceptable, especially for a make like Toyota, supposedly "the best".
Thanks for the heads up, BTW.
Now I gotta start watching a waterpump on a brand freakin' new car........

[auxmike]

The Genuine dealer water pump MSRP is about $100USD. I've seen it OEM on the net for $75USD.
Pump includes parts #8 & #9 in the sketch below.
Hope this helps.....

I agree, it's just kinda funny that most of us have an NST pulley installed.

Are you guys running the TRD rad caps too?
Perhaps too much pressure for the pumps seals?
Hope the Yaris does'nt turn out to be a Japanese Yugo.....

A belt tension gauge should be used to check the tension on the belt and to insure it is with in spec...

yeah well easier than going out and buying a belt tensioner gauge is to just 'eyeball' the deflection.....

where the belt is stretched between the farthest pulleys, push down on it it shouldn't move maybe 1/2" to 3/4" down ---any more and add tension......

[ztrack157]

My pump was $68. There are about $55 otherwise from Kragen/Schucks?checker or whatever the hell they are in your area. Mine is OEM replacement. The others are Cardone.

Haha, Sucks to be you. The Xb water pump is only $53.87, I assumed them to be the same. I see no reason why they would be different, same motor and the pulley must be transfered...

Peter.. Did you ever change out your water pump??...

[YarisSedan]

My water pump has gone out twice already i have 23k miles.

[GeneralDon7]

The dealer actually notified me that mine was leaking when I went in to do that Seat belt tensioner recall. They covered it then (40,000 mi), not sure if i would be now(71000 mi).

[127.0.0.1]

'easier' is not necessarily correct. same with bolt torque.

if you do not have the correct tools,
you have no business in the engine compartment

(not -you-, I mean anyone)

anyhow, water pumps do fail and they are easy to replace. they should last >180,000 though

Someone told me if you can turn your belt to the side with one finger, its tight enough, so thats what I have been doing, I might have to tighten it a littttttle bit just a little because it has been squeaking bad on cold starts only when it warms up its find.


and my water pump hasn't had any problems yet, i have 50,000 miles on my car with the whole nst pulley setup (10 % underdrive crank, wp, alt.)

[bankrobber]

I have 81,000 miles and everything is stock on engine. Not had a problem with water pump yet.

It's exactly the same price as the Yaris one :iono: Your link:
Water pump, xb 04-06 $92.34 $73.87

Unless the 7 is displayed as 5 on some computers :wink:

[TheSilkySmooth]

Hey, is there a water pump lube from toyota or coolant conditioner to add at say 30k miles? - I hear all these problems are from the long life coolant. My Rav4 WP puked at 50k miles too ;(

[kou]

please sticky to DIY section.Thanks.

[OtownYaris]

I just had my water pump replaced today @ 33K miles. The car turns 3 years old this month. Kind of disappointing. The underside of my hood looked exactly as shown in the picture.

[Lucas13]

Mine went out at 55k and other stuff is going out too such as my transmission leaking too!

[bronsin]

I think a Yaris is good but it doesnt appear to enjoy the stellar reliability of its forerunner the ECHO. Never heard of this wp issue with the ECHO and its even the same engine. Some have said the L life coolant is to blame. Does anyone know if any other Toyotas having wp issues? Wife has a Camry with 60k and so far so good.

[auxmike]

Mom's 2006 Corolla pump lasted 16k.

[Klink10]

Just changed mine out last week after 15K. I attribute it to several factors which may or may not have been my fault. In either case I went to a discount OEM parts supplier and got one for $76.00. Did the work myself and changed up my NST pulley install procedure. I really do think that the weakest point on the Toyota waterpump is the seal around the bearing and that care should be used in the removal/install of the pulley and the tightening of the belt. I do know that Toyota offers no additive to the coolant used (Toyota Pink) in the Yaris. I also know that Toyota had 2 types of coolant and some dealers or whatever may still have the obsolete (Toyota Red) still around. The red is straight while the pink is a pre-mix. For info, if you look at the back of the "pink" jug it says that if you flush use only the "pink" to flush with and not "any kind" of water. The logic I assume is that you can't get all your flush out and thus would be dilluting your new stuff. Personally, after having read other stories I took it to heart and went with their advise. I know others have done it different and seem to be doing okay. Me, this is the way I went.

[DARK AGE 53]

if the water pump is covered under the drivetrain warranty then I'm good for life, hopefully I won't have to find out.

[budzrsi]

Hi guys! Anyone knows whether there suppose to sealant applied after the pump is changed? Cos it did come wid an o-ring.

[Klink10]

Hi guys! Anyone knows whether there suppose to sealant applied after the pump is changed? Cos it did come wid an o-ring.

No sealant supplied. The service manual which I used as reference mentioned no sealant either. Didn't use any. Mine is an 07.

[birdman]

Nice write up so now I know where to watch for crystal formation.

[TickleTimeTim]

my hood looked like that but not pink. not sure how long it has been out, but the squeaking is getting worse...like much worse.

[auxmike]

Maybe just the way the belt is tensioned from the factory.

Yeah, I tried to match that factory setting by marking the position with a sharpie when replacing the old pump and I could'nt pull hard enough to even get it THAT darn tight!
I got it close to the factory "mark", and the new pump went about 2k before it started spritzing again....
I check the "new" (2nd) pump almost daily, it only spritzes very little every other day, it's been that way since Xmas. Mabye I'll install a 3rd new pump once the weather improves (I have an AC Delco unit stashed):clap:

[marcus]

looks pretty simple thinking of getting ac delco water pump might be better than toyota..i just dont get how to drop your engine 2 inches..

[ROCKLANDTOYOTA]

NOT A CHANCE 3/36

[goliath1812]

i just dont get how to drop your engine 2 inches..

+1

I removed the bolts from the motor mount, but the motor didn't go anywhere. Even with the jack not supporting it at all....

[auxmike]

Here's my Delco pump and FelPro gasket I keep handy....

[marcus]

thats exactly what i want on the yaris..looks more durable than oem!!

[ROCKLANDTOYOTA]

Here's my Delco pump and FelPro gasket I keep handy....

WHY does the 2 gaskets in the last picture look different??

[Bluevitz-rs]

Put a jack under the oil pan and undo the passenger side motor mount.

[marcus]

Put a jack under the oil pan and undo the passenger side motor mount.

i re read his post over looked removing SIDE MOUNT!!!!!!!!!!! now what side mount is he talking about???

[auxmike]

WHY does the 2 gaskets in the last picture look different??

Because I bought the felpro separately.I also have a new metal oem one.

[ROCKLANDTOYOTA]

Because I bought the felpro separately.I also have a new metal oem one.

must be how im looking at it but they do look DIFFERENT....

[Bluevitz-rs]

i re read his post over looked removing SIDE MOUNT!!!!!!!!!!! now what side mount is he talking about???

Common man, there's only 3 mount on the engine, and I don't think you're going to remove the one on the transmission side.

[auxmike]

must be how im looking at it but they do look DIFFERENT....

I'll see if I can post a pic of those two and the metal oem one after I get home.

[goliath1812]

Put a jack under the oil pan and undo the passenger side motor mount.

I've done that, but the motor still doesn't drop.

[Bluevitz-rs]

I've done that, but the motor still doesn't drop.

you lowered the jack and the motor didn't move?

[goliath1812]

nope, didn't move one bit. the jack wasn't even touching the oil pan.

[auxmike]

I just put a 4ft prybay to the side of the engine and pryed while sliding out the pump...
I did'nt even have to remove a tire.

[sort_o_sane]

Other than the Autozone or Kragen/O'Reilly replacements, is there something a bit better for an aftermarket replacement?

This also makes me want to look into an oil cooling kit for my yari :)

[auxmike]

I bought the AC Delco one. Madeinthe USA !

[sort_o_sane]

Ok, this is going to sound completely stupid, but how in the hell do i get the mount to separate when I'm trying to drop the motor?, bolts removed and the damn thing won't budge. WTH?

[sort_o_sane]

let me also add the i beat the hell out of a pipe i had using it as a pry bar and was tempted to climb onto the engine and jump on it...

[sort_o_sane]

never mind, i'm a dumbass and see the tip of the bolt that held the nut i need to remove...

[bronsin]

I just put a 4ft prybay to the side of the engine and pryed while sliding out the pump...
I did'nt even have to remove a tire.

SWEET!

[auxmike]

I don't recommend doing this any more, I put a nice dent in my a/c line!

[marcus]

you have to take out a bolt anyways might as well take off the ac compressor instead of dropping the engine then the pump will clear i watched the way toyota did it..

[auxmike]

I wouldn't do that, especially without a lift. When I used the prybar I didn't
Mess with any bolts..

[bronsin]

I don't recommend doing this any more, I put a nice dent in my a/c line!



Well now we know better.

Where and what did you pry against? Besides the AC line I mean?

Was it a case of PRY....quick wp out...PRY...quick wp in?

I THINK I can control myself not to rush and think about what I am doing and so avoid ruining my car.

Is it possible to get the old wp off then cut a piece off it with a dremel so as to be able to remove it?

Perhaps there are extrainious parts on the new one that could be ground off to get it in there?

Im like the people who cut jeeps into four pieces with a cutting torch to fly them in C47s over the Hump in WW2 then welded them back together again once they got there.

Whatever works think outside the box.

[auxmike]

Bronsin, I pried on the center of the crank pulley, NOT the timing chain cover. You have to pull REAL hard whist sliding out the pumps. Those AC lines are thin aluminum tubing,watch out!

[c-dub]

did my girls today. didn't drop the motor, but needed to pry it back about 1/2" to get the pump out and in. used a 1/2" breaker bar between the motor mount and the head. didn't need any force, the blocked moved easy.

[junorico24]

When you said you dropped it 2 inches. Did you undo the the motor mount bolts?

[sort_o_sane]

yes, just on the passenger side. both or at least there were 2 on mne

[baseballfan416]

Did you drain coolant or merely have to fill it back to acceptable range given the amount that leaked from the pump?

[baseballfan416]

on yaris from 2003, i´m trying to follow this DIY... already remove the two bolts from passenger side mout but no drop. What is missing? thanks

[hw6515]

I though of adding that to the guide at some point, there is a 3rd bolt from the bottom.

I can tell you the size or make a pic if you need it.

ok! ia go to the car and see it now ( and try to continue the replacement :)
Thanks

[hw6515]

refresh the page, pic is in my previous post.

support the engine before loosing the final bolt.

If you have any other question, let me know.

[cbmago]

refresh the page, pic is in my previous post.

Got it! :)) spent almost all afternoon trying to find why!!!!!!!!

Thank you very much for your help :)

[murfy]

Yaris Verso 2000, I loosened the 2 top bolts on the engine mount and the nut on the underside of the mount a couple of turns, I then got a nail bar and some wood and levered the engine, this shifted the engine enough so the pump came out easily.

Thanks for the original guide

[bronsin]

Whats a nail bar? :iono:

[ws6toto]

I just did my waterpump on my 2007 yaris two weeks ago i didnt had to loosen the two top bolts from passenger side mount,I had enough room to take out and install the waterpump,I just took the waterpump pulley off.

[Veganman]

I just changed out the water pump on our 2007 Yaris at 190,000 miles. It never leaked a drop but began making a disturbing noise that was very difficult to track down. After referring to many posts on Yarisworld, I felt confident the noise was in the pump even though it felt fine when the belt was removed and the pump was turned by hand. The only additional comments I would make are as follows: I never had to lower the front of the engine by 2"; in fact, I didn't lower it at all. The pump can be removed and the new one installed by carefully turning and twisting it a bit.
I bought a replacement pump and a metal gasket from Auto Zone and everything worked out perfectly. Total time to replace the pump and get the car running again was 2 1/2 hours.

Good point. I found that unbolting the AC tubing mount, that sits by the pulley, also helps with being able to remove it without lowering or raising the engine.

Did you buy the Duralast water pump (AWP-9187)? How many miles have you driven since replacing the pump with an aftermarket? Any issues or recommendations?

["G"]

Mine has 200k and is not leaking yet. But I did flush my coolant at the recommended service intervals and only used toyota pink fluid.
