Here's the water pump that came out of my 2001 Forester Automatic donor. So this could be used in lieu of Tom's adaptor?

that may work. i was referring to this:
https://www.ebay.com/itm/291474507584?fits=Model%3...SweW5VYnDg
note, that is some bobo junk one but subaru makes the same one.
i'd be more inclined to run that as you can have the hot water tickle the 'bulb' side of the t stat. basically, tom's adapter did the same thing as the water pump i linked by spacing it down and pissing hot water right at the bulb
you may be able to use that thermostat cover but i would suspect you're temps may be a bit 'spikey' with that cover. this is a non issue in a stock subaru that holds very little coolant, but may pose an issue on the 500 gallons the vanagon holds _________________

Here a WRX pump I found at the U Pull. Stock pump on the right.
I'm thinking I'll use it on my build. I like that it doesn't hang down and the cap already points to the side. The timing belt cover fits just fine. The crusty stuff on the inlets cleaned right off with CLR.
I'll use this to cap off unused inlet.

This car apparently had a good quality timing belt kit and water pump put in just before getting wrecked. I grabbed all the made in Japan idlers and Aisin pump for around $20 _________________ '84 Westy, '93 Subaru ej22 and Subarugears 5speed

SG, to me that appears to have the fitting on the 'wrong' side of the T-Stat.
it won't be in 'constant flow' as is required. it would only flow when the T-stat opened. which may be ok for the OE transmission return loop. but not satisfy the lack of return water via the heater hose from a vanagon shut off valve.
so NOPE. this alone is insufficient.
either a turbo water pump, a Shiels adapter or a return loop heater valve.

Glad you guys pointed that out in my picture! I realized too that the connection with the hose on it in my pic is for outbound coolant to the oil cooler beehive. _________________ 1986 Volkswagen Vanagon Westfalia "Von Westy"

it's actually inbound/returning coolant.
the T-stat regulates the return (cold supply) side of the loop.
the small hoses that attach to the Pump are returns from their various loops.
heater core return and trans cooler return (and turbo return)
the trans cooler return will be closed when the T-stat is closed
where as the heater (and turbo) returns are in constant flow.. and this gives the T-stat an positive indication of the coolant temperature
unless installed in a vanagon with a closed non-returning heater valve.
sorry to be pedantic but it's best to stay clear on this and iron out any confusion.. _________________

There is a two nipple WP for the auto trans Forrester available in 2002 (Rockauto).
The rear facing (on van) nipple might make a tight fit with the Smallcar mount but a 90 degree hose should work.
There is a side facing two nipple available for the 2004 turbo Forrester (even a three nipple)
Cast impeller was better than the stamped last I read. The original Subaru WP gasket is metal. |

Like anything in life
the position of the nipple is important.
again, if that rear facing automatic nipple is as in the image posted above..
then it is on the wrong side of the waterpump to properly flow to prevent overheating of a vanagon installation.
just because it has an extra one, does not mean it will function as needed.

i'm just going to throw this out....
i'd pony up for a subaru pump. even the aisin pumps i have used don't seem to hold up as well as a genuine subaru pump even though they are made by aisin.
i for sure wouldn't use a rock auto pump or rock auto anything in the timing belt area. call me a parts snob but i have seen too much in all of my years doing this for a living _________________

they are, but for some reason they don't seem to be as good as one from the dealer.
i use to use them but i had 2 leak. one with 20k on it and the other with 35k _________________

Don't think so. The two nipple WPs on Rockauto and shown on the Ebay link are different from the pic shown by the OP. Both nipples are topside.
I got a NPW WP from Ebay that has worked just fine. Aisin and GMB are both Made in Japan I think. Rockauto parts work just fine. |
