Power Steering Pump Leak 900

Hi All,

945 Turbo SW 2.0L - 1997

My car has been leaking some fluid for years in the steering pump area.
Today I cleaned the pump as best as I could to identify where this is coming from, and it looks like the suction hose is the culprit.





From VIDA, I got the P/N 3530083, the clamp holding it in place seems to be tight, how is it possible that it leaks from there?
On the other hand, it is wet, and if I pass my finger under the hose, I can see enough oil to explain the drops.

Before I do anything, I need to be sure.

As always, your advice is very welcome.

Thank you!
Alex

    Power Steering Pump Leak 900

    Dear Metallo,

    Hope you're well and stay so! The suction (return) hose may simply have failed. Over 20 years, I recall few posts about leaking power steering pumps.

    I'd further clean the pump housing, replace the hose, tighten the hose clamps until "snug", and wait. Hoses generally fail from the inside, unless damaged externally by friction (rubbing), lube oil (which softens rubber) etc.

    When removing the hose from the power steering reservoir, take care. Old plastic can be brittle, especially when it is cold. It is best to slit the hose longitudinally, making very shallow cuts, for, say, 1.5" (40 mm). Use a small, flat-bladed screwdriver to spread the hose on either side of the cut. The goal is not to have to cut to the point, where the knife blade contacts the pump's plastic hose nipple.

    Hope this helps.

    Yours faithfully,

    Spook

      Hi Spook,

      Thank you so much for your advice.

      I guess I have to drain the power steering fluid to change the suction hose?

        Dear Metallo,

        I would loosen those two banjo bolts underneath the steering rack to drain the fluid away (into a drain pan of course). Key word here is "loosen" meaning not to take them out. All bolts and copper washers are still in place so that no missing parts later. Blow some air into the reservoir opening to push more fluid out. Steer the wheels (easier to do with the front jacked up) to let more fluid out. Retighten the bolts after draining all fluid. This way the system is almost dry.

        No nasty surprises of fluid spilling on floor or front engine pan while doing your repair.

        Do the same if you want to flush old steering fluid out. No more turkey baster method.

        Amarin.

        Dear Metallo,

        Hope you're well and stay so. You can use a turkey baster - a plastic tube with a rubber suction bulb - to empty the power steering reservoir, before you remove the return hose. That will make the job way easier.

        Once you remove the hose from the reservoir, raise the hose's end, so it is above the reservoir. Then put that end of the hose in a plastic bag, and rubber-band it tightly, about four inches from the end, where you sliced the hose to remove it.

        When you lower the bag-covered hose-end to the ground (and so below the pump), fluid in the hose will drain into the plastic bag. You can then dispose of the fluid at a re-cycling center. If there is none near you, some auto parts stores will accept used fluid for re-cycling.

        When you have replaced the hose, re-fill the reservoir with Synthetic ATF (automatic transmission fluid), which is the same as power steering fluid.

        Turn-on the engine and top-up the power steering fluid reservoir. Then, with the engine running, turn wheels from side to side, a couple of times. This "bleeding process" allows any air in the system to rise to the reservoir and exit the system. Add ATF, if needed, until the reservoir's "dip-stick" shows the reservoir is "full".

        Hope this helps.

        Yours faithfully,

        "Spook"
