KenD Posted May 28, 2004 Report Share Posted May 28, 2004 Has anybody bled the power steering system before? If so, was it overly time consuming. I'm thinking of changing the p/s pump on the car and wanted to bleed the system while I was at it. Any suggestions or tips? 1994 STS Pearl White 260,000 KM (163,000 miles) <img src="http://img45.photobucket.com/albums/v137/caesar/caddycaesar.jpg" border="0" class="linked-sig-image" /> Link to comment Share on other sites More sharing options...
Scotty Posted May 28, 2004 Report Share Posted May 28, 2004 If I recall the proper way to bleed the power steering pump is to jack up the car so both front wheels are off the ground and turn the steering wheel lock to lock repeatedly pausing at the stops. If it still growns repeat the process. Mike Link to comment Share on other sites More sharing options...
CadiKing Posted May 28, 2004 Report Share Posted May 28, 2004 KenD, I am looking to change the power steering fluid as it smells burnt. Occasionally I get a slight studder in the wheel, that's what made me think it would be prudent to change the fluid. I never thought it might be air in the system! Does anyone know if air would cause a studder? I could not find the post, however, a while back someone explained how they changed the fluid by removing the return line and pumping it into a bucket while keeping the reservoir full. Any one know how to find that post? Link to comment Share on other sites More sharing options...
KenD Posted May 28, 2004 Author Report Share Posted May 28, 2004 In my service manual it's a two person job. Scotty is right about jacking up the front end and supporting it and then turning the wheels about 20 times to each stop point a the while keeping the reseviour topped up while doing it to get fresh fluid into the system. You have to take off the return hose and have the end in a bucket to collect the bad fluid. My fluid smells burnt also. If I had a scanner, I'd scan the page for you. It looks pretty simple to do but you know how it goes when something seems too easy sometimes.... 1994 STS Pearl White 260,000 KM (163,000 miles) <img src="http://img45.photobucket.com/albums/v137/caesar/caddycaesar.jpg" border="0" class="linked-sig-image" /> Link to comment Share on other sites More sharing options...
CadiKing Posted May 28, 2004 Report Share Posted May 28, 2004 KenD, Thanks for the response... Does the manual say how much fluid it will take? I take it you mean to turn the steering wheel side to side while adding fresh fluid as the old fluid is being pumped into a bucket. Is this special fluid for the magnasteer? Dealer Only? thanks again... Link to comment Share on other sites More sharing options...
STS Scott Posted May 28, 2004 Report Share Posted May 28, 2004 Do you guys mean to say I can eliminate my power steering whine? I thought I was just a trait of any aging car, and I just had to accept it. I am assuming there is air in MY system then too? Thanks!

JimD Posted May 28, 2004 Report Share Posted May 28, 2004 .... Is this special fluid for the magnasteer? Dealer Only? Any GM parts counter will have PN 89020661 power steering fluid bottled for GM systems. It is a mineral oil based fluid with appropriate additives to prevent foaming and corrosion.

KenD Posted May 28, 2004 Author Report Share Posted May 28, 2004 Does the manual say how much fluid it will take? If I'm not mistaken, I think it was about 900 ml or almost a litre. Most power steering fluid containers that I have seen were about 950 ml. Sorry, I don't know the conversion to imperial for ya, I was just a toddler when they switched over to the metric system here in the Great White North so I can't give it to you in imperial terms. 1994 STS Pearl White 260,000 KM (163,000 miles) <img src="http://img45.photobucket.com/albums/v137/caesar/caddycaesar.jpg" border="0" class="linked-sig-image" /> Link to comment Share on other sites More sharing options...
CadiKing Posted May 28, 2004 Report Share Posted May 28, 2004 Thanks KenD, I will Buy two liters/quarts. That should do it! You mentioned the Great White North. I live new the north coast of America, but not near enough to the large hills/mountains to really enjoy the winters without travelling. Last winter we spent some time at Whistler/Black Mountain snowboarding/skiing. I would give anything to live in the Great White North as it really is GREAT and WHITE with Snow. Gotta love that traction control - aye? Link to comment Share on other sites More sharing options...
KenD Posted May 28, 2004 Author Report Share Posted May 28, 2004 Hey, come up anytime and spend some of that Yankee green!! Whistler is AWESOME!! Done lots of skiing there on the boy's weeks out, if ya know what I mean....! Lived in Phoenix for a while and did lots of skiing in the White Mountains and Tahoe and Taos, plus Denver. Nothing like partying with the Canucks though. Oh, by the way, it's "eh" for the Canucks and "aye" or "oye" for the Aussies. I know, I know, da*n Commonwealth countries. I would be changing the PS fluid and pump this weekend, but it's supposed to rain AGAIN, so it'll have to be the next couple of weeks or when I get the urge. If you get to it sooner than me, let me know how it goes.

Any idea how much to buy to flush system? <_> One U.S. quart (946 ml) will do it if you stop pumping when you see clean fluid. I don't open the plumbing when I refresh the fluid. I empty the reservoir with a turkey baster and fill with fresh. Repeat several times with a few days of driving in between. Not a 100% flush, but pretty close. Jim Drive your car.

That place is amazing! Daughter lived in Washington state up until this spring. Skiing/Snowboarding this past winter at Crystal Mountain in Wa was good, but when we got to Whistler...there is no comparision! Whistler is a city of snow beauty! Is your pump bad? How can you tell? You're loosing me on the Canucks and Aussies. Who is Who? Thanks for the invite...Might just take you up on that! Have to remember the sun glasses, so I don't get snowblind and miss all that Beauty!

I do not recall that the return hose had to be disconnected to bleed the air out of the system. Maybe you are speaking of purging the system or changing the fluid? I was under the impression that raising the wheels off the ground and turning the wheels back and forth against the stops was all that was necessary to 'bleed' the air out of the system, Thanks, Mike Link to comment Share on other sites More sharing options...

KenD, the shudder you describe may be your belt slipping, check your tensioner to see if its is applying proper pressure and see that your belt is not dry rotted or glazed.

Scotty Posted May 28, 2004 Report Share Posted May 28, 2004 Ahh, maybe we are talking about different things, when you said bleed the system I am thinking you are tying to 'bleed' the air out after you changed the pump, a normal thing to do, however, if you are speaking about flushing the system fluid out, thats different and maybe that is what you are trying to do and in that instance you could accomplish that with the return hose.... air in the system will groan, and feel slightly sluggish after the pump is changed. Lately at my 3,000 mile oil changes, I have been pumping out as much power steering fluid as I can and refilling it, I also pump out about two quarts of tranny fluid and refill also (call me anal i know....but its an easy process, lol) Mike Link to comment Share on other sites More sharing options...
KenD Posted May 28, 2004 Author Report Share Posted May 28, 2004 My fault Scotty, you're absolutely correct for the bleeding proceedure. I was referring to the flushing proceedure when you have to take the return hose off and place it into a bucket. Once the old fluid is flushed from the system then you have to bleed it by the way you described with raising the wheels off the ground and turning them from stop to stop about 20 times to get the air out. My bad. (BTW the proceedure is on page 3B-4 - 3B-5 in the manual.) 1994 STS Pearl White 260,000 KM (163,000 miles) <img src="http://img45.photobucket.com/albums/v137/caesar/caddycaesar.jpg" border="0" class="linked-sig-image" /> Link to comment Share on other sites More sharing options...
rmac-etc Posted May 29, 2004 Report Share Posted May 29, 2004 I replaced my ps pump recently and the bleeding proceedure that I followed I got on these pages somewhere and it worked well. No whine. It's pretty simple, raise both front wheels off the ground. Turn the steering wheel lock to lock 20 cycles, ie both directions (engine not running). Keep an eye on the reservoir, it will probably overflow. Then lower the car, start the engine and repeat the 20 lock to lock steering excersize. I am pretty sure that is what I did, and it did the job. Link to comment Share on other sites More sharing options...
