I would use ATF fluid. I used Dexron IV and it made my pump whine / there was more resistance when turning the wheel. I reflushed with ATF fluid and it's as good as it was (just no leaks now).

Materials needed:
Rag (for spillage).
Turkey baster (to suck out the fluid).
ATF fluid (should have at least 3 quarts).
Empty container or jug (to hold old fluid).
One Silvia or Silvia derivative.

FIlling up after replacing line:
1. Pop the hood.
2. Remove PS cap off reservoir.
3. Fill reservoir with fluid (assuming you replaced a line and drained it).
4. Start car.
5. Move steering wheel all the way to the right. Then all the way to the left. Stop if you hear air getting sucked in the pump [Repeat this step 2x, this is optional but I did it multiple times anyway]
6. Top off reservoir again.
7. Repeat steps 5-6 until there's no more air in the system.

Flushing (assuming you do this right after filling):
1. Remove the power steering res filter, put it somewhere CLEAN and be careful not to get dirt inside.
2. Use turkey baster to remove ~75% of the old fluid out of the reservoir. Put it into the container. I used a Tupperware container. Be careful not to remove too much, or you'll introduce air into the system.
3. Fill reservoir back up. (Although it's hard to tell, the fluid in the res is moving through the system / mixing)
4. Turn wheel all the way left, then all the way right. By all the way, I mean the bump stops. You'll feel them. [Repeat 2x, again optional]
5. Repeat steps 2-4 until the fluid coming out (should be dark red at first) looks like the fluid going in (light red). If you use all the fluid, make sure that if you go back to step 2 you have enough fluid for step 4.
6. Put filter back in.
7. Put cap back on.
8. Drop hood.
9. Go to the nearest parking lot and rip some hektik skidz yo.

If you need help with the power steering line, PM me. I might do a writeup soon. EDIT: If you have A/C + emissions hooked up, be prepared for a world of pain trying to get off the hardline bracket. If I did this again, I would try to take the hardline off the PS line and not even touch the hardlines otherwise. Be extra careful with the hardlines. You do not want to round off the fittings, it's quite easy.

No problem! The other writeup requires you have a fluid pump and isn't very specific lol. Didn't like it too much.

thanks for this im doing this soon. my ps is perfect in the summer but since its been getting a bit colder its seems a bit stiff, im sure a flush with some good atf will solve the problem the fluid in there is probably from like the mid 90s or something.

Dexron III ATF is what Nissan spec'd. Dexron IV is compatible with III, so I don't know what kind of issues Mercury^2 was having.

Dex III is becoming hard to find... ATF for older GM is what you need.
