Found a 2000 S70 at salvage yard and it appears the power steering pump is the same configuration as my daughter's '99 S70, except possibly for the size of the pulley. Can I take the pulley off the '99 and make it work on the 2000 pump? If so, how difficult is it to remove the pulleys?
Thanks in advance.

 

FYI..There's a guy on Ebay US who is selling early S70 P/S pumps brand new in the box for $25 ! I believe there is some change in the pumps early in the series which is probably well known here ? I did purchase one anyway, which fitted my 1997 S70 fine and is working A1 ( albeit for only about 3000klm so far ) They do come sans pulley so you have to swap yours over. He ships O/S no problem and mine cost $82 all up shipped to Sydney, Australia. Funny when others on ebay US are advertising reco pups at $190 exchange with $35 deposit. I'm tempted to buy another for a spare. If you want to give it a look the current auction is NO. 280563020187 cheers.

 

Sorry, meant to say that the pulleys are fairly easy to fit. I have a press, but a good quality push/puller would do it fine. It is not advisable to use a 3 leg type puller on them as the pulley would be easily distorted.
You need a setup that places a flat surface under the pulley and spreads the load around a fair part of the pulley's diameter.
It's a 5 minute job for a shop and so it shouldn't cost much to have it done if you haven't the gear yourself.
It's a straight push on/push off press fit. I'd go to a P/S service to have it done regardless of which pump you buy.
That's just my humble opinion of course. good luck.

 

Thanks GCM, unfortunately, they changed the PS pump setup in '99 and the fluid reservoir is separate. From everything I can gather, the pumps on the '99 and 2000 are the same but the pulley on the 2000 is a little larger. I'll see if my mechanic can swap the pulleys for me or I'll go to Advance Auto and borrow a puller. My only concern is the threads on the Volvo pulley.

 

FYI, Chris Delano of IPDusa responded to my email query with this: The power steering pumps are the same, but they did use different belts in those years which would be related to the pulley.
I'll be giving IPDusa my business in the future.

 

Borrowed PS pulley puller from O'Reilly's Saturday and pulled the pulley off the 2000 pump and put it on the shelf. Pulled the pulley off the 1999 and pressed it on the 2000 pump. Installed with new PS fluid and it's done. Used a mix of Maxlife PS fluid and Pentosin CHF 11S. The Pentosin looks pretty thin. If I drain and refill again, will a fill with Pentosin only lead to steering rack leaks?
