Has anyone used the stock AAZ power steering pump for a water I.C.pump for there water cooled intercooler ?
I look at the fittings on the pump and I think this will work ?
what kinda of psi does the pump create ?
Cheers !

It might! just work with water and that soluble oil used for cooling machine tools and lathes, but there might be a reason why nobody else has done this. ;)

I was thinking of synthetic water ( Water Wetter )????
-
i think it would be easier to just run an eletric water pump, they can't be expensive
-
long as you ran some sort of water lube for the rust you will be fine(they sell it at napa).....will a PS pump actually move water?? or is water too thin?
-
Why not just run PS fluid? Could the PS fluid carry enough heat away? And yes, electric water pumps can be found cheap. I watched a new genuine Audi one on eBay sell for $10 last week. You can also spend a lot of more on one. PWR sells a Bosch one for $179.

I love the idea and the thinking outside of the box. I would do it if I were you and tell us how it goes. My only concern is how much HP will it rob to drive it? When dirt track racing we usually got rid of the PS pump and the alt and it helped the throttle response quite a bit. How much difference between the electric pump draw and the PS pump only you could tell us:D.

if hes already got the P/S pump, then why not? if it works then awesome, if not then switch to a electric pump. the porsche ones work wicked, my friend is using one on a tdi.

i was under the impression that pwr steering pumps pumped at very very high pressure...
-
That's what I was thinking...
Just a Idea out of the box.. ;)
-
why not use a VR6 aux coolant pump? you can get them all day used for 20 bux or less.
-
I will do bosch ( new ) , pull the ps pump off
Doing a PD150 WITH A WATER COOLED I.C.
Iam going to have manifold drilled and tapped for the mcnally guage , then to extrudeahone for polishing , then off to powder coating

basically a knock off shur-flo wash down pump. see them on alot of boats. dont move much volume. but the impellers last forever. not high pressure or high volume. i would use a centrifugal pump, like whats found on VR6's and newer vw's. maybe not that exact pump, but something like it. centrifugal pumps dont have very high pressure, but they move alot of volume.

240gph is pretty good volume I would say?? you dont really need any pressure...just be able to move the fluid through a cooler...
-
there is no way those pumps flow 4 gpm. i used lots of those stupid little pumps up in alaska, and they didnt move near that much water/fluid. but it would probably work just fine for a2w IC coolant pump, just not my preference.
-
A pump won't create pressure unless theres a restriction. I would just wonder how much volume the ps pump would move. A prob i see with using power steering fluid much like atf is if you had a leak your engine could ingest that and run off on you. The tractor pullers use a water soluable oil for their water injection systems. They use a high pressure high volume pump similar to a ps pump. If i didn't hate the ps brkts and belt setup i'd be up for doing it.

I got a few of those (and the 260 model) recently, and although they'll work, they aren't ideal unless you can get them really really cheaply. They pull a lot of current (240 uses 4A with no load) and are fairly noisy. Also, they are rated for intermittent use only. So you will need to have it under some form of PWM or similar control.
Another electric pump to throw in the mix is the aux coolant pump on the MB's. Pulls 1A and moves around 3-4gpm. ;D
