Which Power Steering Pump to Get

Post by Rileysowner » Fri Aug 09, 2013 1:20 pm

Looking at the various options in PS pumps and I find that it is not only the with or without reservoir, but also whether it includes the EVO or not, which I assume means if it does not you use the EVO currently on the system. So what sold I order. The least expensive option is without the reservoir, but that adds additional work.

I usually ask the parts store for the pump listed for my year make and model of van.
Then they ask if I want a reservoir or not.
I choose not, because the reservoir is just a container that the pump sits in.
If its an external reservoir style, the pump still lives in a container of a different shape, that you dont need to buy.
Confused now?

Yes, the pump sits in the reservoir. I take it that switching it is not that difficult?

I've had about 3 of those fail. Usually whilst doing big noisy donuts in a snowy parking lot during the first snowfall ! LOL, Remember that !
Yes, its a bunch cheaper to just buy the pump, without a res. Its easy enough to change it out.
Pretty sure the ones that have an external res are the same design of pump in a different shape container.
Getting the pullly off is the challenge! You need a pulley puller.

While I'm crawling under the van replacing the oil pan, figured I may as well replace the PS pump that's been leaking pretty bad. I cleaned it all up and found that it's not leaking from any of the hoses or connections, but running down the back of the reservoir from a location I cannot see (not the supply line). I have no experience w/power steering so my question is: should I go for a reman or suck up the extra hundred for a new?

It seems my van is springing leaks everywhere lately! Photo_van, mine is doing the same thing, I just replaced the weeping power steering cooler return line and am considering a rebuild kit for the pump. Cheap and how hard can it be? Plenty of how-to guides out there... If I don't do that, it will be a new AC Delco pump for sure as I just don't have much faith in some of the rebuild stuff out there.

wow! That Delco pump is priced right for new!!?? Unfortunately it doesn't seem to fit a 98 which seems weird :-s Anybody out there know what the difference is?

To good to be true; READ THE FINE PRINT!

"100% new, premium-grade seals, including high-temperature double-lip Viton seals for durability and reliability
Surface wear on cam packs are micro-finished for durable, quiet operation"

the seals are 100% new! There is no "surface wear" on a new pump that needs to be "micro finished".....

That's interesting though I wonder if that isn't just some stock (mis) information they have listed.

AC Delco #36-0057 is listed as "GM Original Equipment", not reman on the AC Delco site: http://parts-catalog.acdelco.com/catalo ... search.php

I emailed AC Delco asking for clarification and I'll post the reply.

Rock Auto also references the same OE info along with the original part #88963501 which can be had for $120 or so from GM Parts East: http://www.gmpartseast.com/Page_Product ... =53M&Year=

My bet is that it is a new pump but curious to know for sure now.

AC Delco site lists as fitting 2002-2005, GM Parts East 1999-2005 and Rock Auto 1996-2005 so I think you'd be fine with that pump.

Thanks for that info, it will be good to get it from the manufacturers mouth! I started questioning it when I went to "more info" and it talked about reman pumps.

Thanks for researching it! :cheers:

Great, thanks. Just ordered one. Got mine out today. Not a bad job, took a couple of hours. The rear hanger nut was awkward. It's good to know that bracket is slotted so you don't have to remove the nut.

Got my new AC Delco PS pump installed ($127 thru Amazon). The pump differs from the 97 and 98 models in that it doesn't have the EVO unit on back and that it is ~$200 cheaper.

Using this pump required using a newer (99) high pressure line.

The EVO was acting up at snow speeds anyway so I'm happy to be rid of it

That's interesting, I don't remember my '97 having EVO but it's been so long I could have forgotten! New pump is looking good! :cheers:
