Jolbaru_LGT Posted March 18, 2021 Share Posted March 18, 2021 Hi, so it looks like I've got a leak at the power steering pump. Wondering how I can fix this easily and painlessly. The reservoir was at or a bit below "low cold." I just topped it off to "cold max" with Amsoil ATF. I have a feeling it's been leaking for a while, but I've just replaced my timing belt and cleaned the engine pretty well, so the crusty oil soak is new. Any help or suggestions would be great!

apexi Posted March 18, 2021 Share Posted March 18, 2021 Have you replaced the o-ring before? Subaru part #34439FG000 pic https://legacygt.com/forums/showpost.php?p=5091736&postcount=115 Link to comment Share on other sites More sharing options...

apexi Posted March 18, 2021 Share Posted March 18, 2021 Pretty easy, you don't have to replace the fluid. You might lose a little bit of fluid, so it's good to have a little extra on hand. I'd buy 2 o-rings to be safe, since they're cheap. I worry about possibly damaging one if you try putting it into the pump, and maybe hitting it with the elbow by accident. What I think most people do is they remove the 10mm bolt holding the plastic elbow on, remove the plastic elbow from the pump, put your finger over the hole in the plastic elbow so fluid doesn't spill everywhere, put the o-ring down in the pump and quickly put the elbow back down in. From what I remember, that didn't work for me, I think I had a little leak. So instead of putting the o-ring into the pump, I put it on the plastic elbow, and then put the elbow back down into a pump. This way is probably a little messier.

socalsleeper Posted March 18, 2021 Share Posted March 18, 2021 Make sure you pinch the hose from the reservoir to the pump since it sits higher than the pump it will make a mess if you don't. Also Trans fluid makes a lot of smoke when it burns on you manifold which is right below. Link to comment Share on other sites More sharing options...
BoozeRS05 Posted March 19, 2021 Share Posted March 19, 2021 (edited) It's easy. Definitely recommend putting the new oring on the elbow and not into the pump. As long as you hold the line up it shouldn't spill much and shouldn't need to clamp the line, just a rag to catch/wipe excess and refill reservoir. Couple tight turns in each direction in an empty parking lot after and check fluid.

Pleides Posted March 19, 2021 Share Posted March 19, 2021 Surgeline did my o-ring months ago and later replaced my old fluid. Seems to be a common point of failure on these cars. It did not appear super difficult to do. Link to comment Share on other sites More sharing options...
Artizan Posted March 19, 2021 Share Posted March 19, 2021 Start with the suggested o-ring. If that doesn't stop the leak, it's your power steering pump itself. Not a difficult job either, if you have to replace the pump. Link to comment Share on other sites More sharing options...
Guest Posted March 21, 2021 Share Posted March 21, 2021 (edited) You should be able to tell if it's the o-ring or elsewhere in the pump. O-ring will have residue on the suction line. Oil really should not pool under the pump due to this. If it does it's almost certainly pump. My started leaking - oil was pooling under it. I replaced it with brand new OEM, which is stupid expensive (~$380). I did not want to chance aftermarket and did not have time to do rebuild. Subaru sells rebuild kit with all the internal gaskets. If interested I can sell my old pump real cheap so you can do rebuild without disabling the car and then just do the swap which is quite easy (<1h job).

I did not want to chance aftermarket and did not have time to do rebuild. . That's the route I ended up taking too. I went through two ac delco professional remans that both leaked, seemingly from the center where the pump halves mate and there is one large o-ring, but I can't say for sure. Got tired of swapping the pumps out and cleaning up the mess. You can sometimes get lucky buying oem parts on ebay, I got a new pump for around $305 or $310 shipped from Quirk parts.
