I saw a used one on ebay for $40 with a 3-mo. warranty the other day, I think the auction had a day or two left. No bids, should still be up. Some things I would not buy used, but a ps pump is not that critical. I would have bought it but I already have a used spare... ;)

Usually they can be rebuilt if you find a kit or match the seals, but not as easy as it seems. There is usually the internal pressure relief valve, and a good rebuild would have to deal with that...

For $70, I would let a mechanic do it, but it is not difficult, just a bit messy.

You will need to soak the pipe thread and the bolts at the pump with PB Blaster or some other kind of penetrating oil.

New o-ring seal, not sure what size, Saab p/n 4104048. New hose clamp, p/n 7970072. Looks like you might need a flare nut wrench, not sure what size, to get a good grip on the pipe fitting. Any part store or Sears will have those.

I will probably replace the ps fluid when I do mine, but it sounds like you don't have much of the old fluid left anyway...:cheesy:

What a bugger! I drove home today with my spare bottle fo CHF11S handy and when I got home.. NO LEAK!? :confused:
Sorry dude, what a nightmare...

As far as I know 1995 and 96 cars use GM Power Steering Fluid, says so in my owners manual, not sure after those years. If not, then I have been adding the wrong stuff... <sigh> do NOT mix the fluids (as in "do not cross the streams")

Aside from that... The pressure in the ps system can vary. Some leaks are intermittent, because pressure spikes in the system when you turn the steering wheel hard to one side (google "power steering" and "pressure spikes"). People sometimes blow the rack seals while trying to get the car out of a tight parking spot, or while replacing the fluid the old fashioned way, by turning the wheel back and forth to help pump it out. In Europe they blame the smaller Saginaw racks, but I don't think that is likely accurate. Saginaw has been making car parts for a while now.

I would turn the wheel all the way, and have someone watch the seal (not from up close, at least not w/o safety glasses) don't wear your good shoes, either...

Replace the pump, and even the hoses that are subject to excessive heat...
There is only one hose w/o a hard line attached. The whole system is a nightmare when it starts to go. The hard lines are crimped to the hoses, and there are three of those. Only one is available as an aftermarket part (I think). Oem, the combination lines are very expensive. The hoses are reinforced, and the rubber parts seem to be in better shape than the crimp joints and the metal lines on my car... the cooling line is BELOW the oil cooler where all the salt goes, and rusts out... the barbed plastic ends at the reservoir tend to break while taking off a stuck hose... how they can stick to the plastic, and at the same time leak eludes me completely... my pet rant, ranks even above the SID... :x ;oops:

When I get the new pump, should I put in CHF11S or GM Power Steering Fluid?
I checked the Pentosin web site, and there is nothing to say whether you can mix that fluid or not.

I would check with the dealer, tell them you found out the old owner's manual said GM fluid, see what they say. Flushing the whole system if you don't need to would be silly.
