Water pump replacements?

[Mika]

What do you folks use as a replacement water pump for the SVX?

There are two Subaru part codes that seem relevant:
21111AA033 - this pump is with two outlets
21111AA070 - this pump is with three outlets, with one line going to the oil cooler. There's only one picture of this pump in the internet, and the code is not recognized by Subaru but should be a valid FHI code.

So far the two pumps that we've tried are Aisin WPF002 and WPF006.
WPF002 does not fit, and has only one outlet, despite marketed as a replacement pump.
WPF006 roller would leave about half an inch of the timing belt unsupported, looks like it's too short to be used.

I'm aware of GMB160-2050, which seems to be a bit better on how far up the roller reaches. I haven't seen if they have a three outlet version available for the pump.

Any tips and ideas what pump would fit from which vendor? We can probably make do with two outlets. Wouldn't want to reuse the old pump, unless I absolutely have to.

Hello,

Is 21111AA033 no longer available now?

According to part list, compatible parts of X211AA000 (water pump kit) are

21111AA033 water pump complete
21114AA051 gasket water pump
21116AA020 sealing water pump
21234AA010 gasket thermostat

Also yahoo says

21111AA033 21111-AA060 21111-AA061 21111-AA062

Genuine 21111-AA062 seems still available.　JPY17,900

Also, GWSU-12A of GMB JPY6,390 seems okey.

Pls check it.

Thank you Noriyasu for taking your time to reply.

Apologies for not posting pictures earlier, this should make it a bit easier to see the issue. The SVX in question is MY1992 - as far as I know.

Here's the pump from the vehicle, with three outlets, one of them towards the oil cooler.


I've added a couple of markers to this photo to show a couple of features of the original pump.


Here's WPF006 from Aisin (it has three outlets too), with added markers. The roller in the Aisin pump is not high enough for the timing belt to fully latch on.


I'd need to see photos of the water pumps from this angle to check if they actually fit. I don't know if there's something odd in my SVX, or if the oil cooler has been retrofitted into it at some point.

Yahoo Japan does not ship goods to European Economic Area, so the link does not open for me.

GWSU-12B has one water outlet, we'd prefer a pump with at least two outlets. We can circumvent the need for the third outlet as long as the pump fits.

I'd need to get Monotaro's page translated somehow to order something from them. A genuine 21111AA033 does not seem to be available here, but I'll go check from the local Subaru dealer.

Oh, Finland...

Can you see this ?

I wrote this just to see compatibility. In the photo, there are only two outlet.

I found the photo when I replace the water pump and attach these. mine is '92. Pls refer. outlet seems two except thermostat in this photo too.

Also, important distance is from is from the engine block to the top(or bottom) of the pulley. Also, from block to base of idler. Pls try to measure it.
It may just be the mounting height of the thermostat cover that is different. It doesn't seem to interfere with the timing belt cover.

For the monotaro, it will ship only Japan domestic. I sometimes refer to this shopping site to check if the part has been discontinued or not. Discontinued parts usually appear as such. For reference, it's a little more expensive than buying from a dealer because of the shipping charges.

21111-AA061 seems discontinued.
21111-AA062 seems still available. I'm not sure it shape quite same as AA033

You may able to get from ebay.

Hi

WPF-008,21111-AA060/061 and GWSU-16A seems does not fit to SVX. See review of amazon.

https://www.amazon.com/Aisin-WPF-008.../dp/B008EEYXZW

umm.

[Mika]

Thank you for these checks!

I can see the translated page, but the pictures are not loading.

Yes, I'm actually Finnish. Here, Mika is a male name, which has caused a couple of confusions on my travels to Taiwan. Can't imagine what it would be in Japan.

We measured the distance from the engine block to the pulley top, WPF006 is about 10 mm shorter. It does look like the pulley height in 21111-061/62 is not high enough as stated in the review.

There is an Ebay option of the GMB water pump which seems to be of correct height. In the manufacturer's pictures, it does seem to have similar height.

All EU Spec SVX have the oil cooler, its one of the measures to get them Autobahn ready. Another one are the vented brake discs on the rear which -big surprise- arent available anymore, just like the water pumps.

Basicly the go to is that you only change the SVX waterpump if you absolutely have to and you always look for a company that restores the old one.

Another option was to get a foreign water pump (usually US as its cheapest to order from them) and have a company weld on the missing inlet.

But afaik original water pumps are out of stock completely and cant be ordered anywhere anymore. The gmb waterpumps might be a good replacement but I hope some americans can give some information on them. The GMB head gasket and timing belt stuff is usually pretty good.

Hello, I understand the reason for the third outlet. Thanks.

And, I agree with quality of GMB. I used GMB WP for old SUBARUs (not SVX) and no problem for now.

By the way, the oil cooler transfers the heat from the engine oil to the coolant. The water temperature in SVX tends to rise to begin with, but I feel like this will accelerate it. Does the EU specification SVX also have a upgraded radiator?

The water thermometer in the meter cluster has hysteresis, so you cannot see changes in temperature within the normal range. If you look at the SSM, you can clearly see that the water temperature is rising quickly.

BTW, for the 3rd outlet for oil-cooler, wouldn't it be safer to add an outlet with a T-joint? I am reluctant to modify WP.

Great help, everyone. Tks.

In summary...
EU spec SVX has 3 "barb" water pump.
US spec has 2 barb water pump.
Neither is available from Subaru.

A few non-OEM suppliers claim proper fit, but not verified by anyone on this site.
For non-OEM, I have seen:
GMB: https://gmb.net/product/160-2050/
Carquest: https://shop.advanceautoparts.com/p/...ctedStore=7616
USMW: https://www.usmotorworks.com/catalog/

So, bottom line...
(1) Can anyone on this forum verify the fit of any of these 3 water pumps...or any other available non-OEM water pump?
(2) And if this forum comes up blank for a verified WP replacement, then just keep my current WP...roll the dice...and look out for coolant leaks for the foreseeable future.

Much appreciated. And feel free to correct or add anything.
Cheers, B.
