Ok so the how to is in the "how to" section (go figure) but for those of us who don't feel like spending mad money on a pump that does not need replacing, I am trying to find the seal mentioned here--- http://www.saabcentral.com/forums/showthread.php?t=179610 --- these are the dimensions of it 17x29.9x7 or 17x30x7 but where can this be sourced.

thanks, (and yes I have googled the $#!t out of this and am only able to find the whole pump assembly)

Can't help you on the seal issue, but if you don't have any luck try finding salvage yards online that have one. I purchased a pump from a 2008 for $40 shipped and no leaks so far.

OMFG!!!


I now understand why my car take 1 liter of precious 0w40 each 1000km and why my powersteering pump always overflow...

Last week I put a ''tracer'' in my oil to inspect the engine with a black light... I wash the engine, we look everywhere except in the damn power steering tank...

Seal - PS

Guys, go to Napa auto parts. They have the seal needed. I put mine in several months ago, no problems at all. As for the flush, flush the entire thing or just vacum out the fluid and replace what you can. It may take a couple times, but you'll get enough out to prevent problems.

seal

go to an industrial bearing supplier you want a 17x30x7mm double lip viton seal,viton is the cadilac seals takes extreme heat,double lip gives 2 sealing surfaces.I'm an industrial mechanic and have changed hundreds of seals.
apply some grease on the seal surfaces during install. :D
p.s. viton is brown in colour

That is awesome news. Along with the previous post saying napa has them. (going there tomorrow) I will be sure to take pics so that people know what is needed. I at this point still am not sure exactly what the seal is going to look like.

I went to NAPA and have called every national auto parts store I can think of. So far no luck getting the high temp seal. The rubber one is available through NAPA. Rubber is good from -40 to 250 degrees F. High Temp is good up to 500 F.

High Temp/Long Life seal stock# 6625
Rubber seal stock# 6622

Here is a page from the book most places will order from.

Here is the Style of Seal:

And the Lip code is:
R = Rubber
V = Long life/High Temp

Hello

I had the same problem ... leaking power steering pump.
First I replaced the O-Ring and in about 2 weeks it started to leak again.
I took the pump out, measured the rubber seal and I went to a company that fabricates such seals to make an order.
After 2 days I installed the new seal on the car, and until now everything works perfect ( 9 months without any leak ).

I will post some pictures with the seal.

today I have a city ride about 30 kms and I check in hot conditions the steering cap level......... over-filler... too much oil.
I think that is the problem......... dealer over-fill it in cold conditions the steering reservoir and it must be done in hot conditions due the oil pressure.

non O-rings support the oil over filler pressure.
I hope this will help

DIY: Seal Replacement

So finally got the new seal in on Thursday. So far no leaks. Total cost: $20 compared to $160 to $380.

Use 13mm to remove the upper and lower bolts. 19mm for bolt on the output and channel locks to remove the clamp on the lower return line. Disconnect or remove the sensor on top of the pump.


Once the pump is out you will see the seal.

Image


I used a small screw driver to pop out the seal. Be carefull as to not scratch the center shaft.

Image


Picture of old (black) and new (brown) seal.

Image

Image


To install place the new seal on and slip it over the shaft. You should be able to press it in a little.

Image


Then I used a 21mm socket and a plastic hammer to tap into place. You don't need to tap to hard.

Image


Then once it's in make sure it is level and not crooked.

Image


Enjoy

I hope so too. The original seal looks to be made of rubber, where as the new replacement is the viton (high temp). I thought I remember reading the saab power steering pump number has changed since the original came out and curious to know if they just installed the viton seals on the new ones to prevent this.

Here is a pic of the seal and package.

Does your PS Rack need replaced

I have this issue with oil leaking out the top of my PS reservoir but my PS fluid never seems to go low, my engine oil does however get low. So I have located the seal at NAPA. My question is, should I replace my pump with a rebuilt or used one while I am in there since engine oil has been cycling through? Secondly, has anyone had any other failures (like their PS rack) after this has happened?

Thank for th input:D

No need to replace the pump unless there are other signs of failure. Replace the seal and flush the system, replace with CHF11S synthetic fluid.

If your power steering reservoir is overflowing and your engine oil level is dropping with no obvious external leak, then yes, you probably have a bad seal on the pump.

The power steering pump is driven directly by the camshaft, the engine side of the assembly is bathed in engine oil to lubricate the contact point. There is a seal on the shaft of the pump that fails and allows engine oil into the pump and then into the steering system and overflows the power steering reservoir.

OK, so apparently not all Napa's order from the same suppliers. Odd. Anyways, if you're trying to find this part try several Napa's before giving up. Also, mine only carried the rubber version, SKF #6622. It's $5.49. Beats $350 for a new pump. Kiss my *** Saab. I wanted the high temp, but the original lasted this long so the new one should too. Fine by me.
