Default I need to drain all power steering fluid. How?

The manual is mute on how to drain all the fluid, but it does mention doing it a couple of times. How can I get all the fluid out?

After my engine swap in which I had the lines off and the re-connected, I (stupidly) filled it with Valvoline synthetic power steering fluid. After start up, I got a shudder through the wheel when turning while stopped or at low speeds. Well, after a quick look at the manual, I saw Subaru specs Dexron III. I drained the resevoir and filled with Amsoil synth Dexron III, but the problem is still there. It seems most of the fluid is in the lines and rack, not the resevoir.

http://www.scoobymods.com/forums/att...achmentid=2131 Right click and save as, or it won't work.

Most people use a turkey baster to suck the fluid out of the reservoir.

Thanks, but I have that in my manual. Under the specs its says that the resevoir holds .3l out of a .7l capacity, so I need to get it all out, not just the bit in the tank. Think of it this way; my power steering needs an enema, I just need to know where to put the nozzle

Take off the return line (not the one that goes to the pump) and start the car. Run it until no more fluid comes out and shut it down. After you refill, start the car and turn the steering wheel lock-to-lock a couple times to get all the air out of the rack.

I'm not sure what you mean. Both lines go to the pump, don't they? Do you mean to take the line that returns fluid to the pump and disconnect that line where it attaches to the rack?

One line from the reservoir feeds the pump. The other is the return from the steering rack. Drain the reservoir, disconnect the line that goes to the steering rack and stick it in a bucket. Almost all the fluid will get pumped out.

The pump relies on the ATF for lubrication. Once all the fluid's out and your engine's still turning the pump, mightn't you do damage to the pump's bearings?

Could you remove the belt and turn the pump by hand instead, so as to put less load on the bearings?

What if he has a manual and has no ATF. I think engine oil for the pump would be more apropriate, unless it uses none. just pointing that first part out, I don't know how the pump works.

Take off a line from the rack (one that comes from the pump or the return), one that is easy to get to, im not sure if they are easy to get too though if they are, put the front end up in the air and then WITH THE CAR OFF turn the wheel back and forth till you pump all the fluid out, that will get the job done the fastest, easiest and safest way

Do not run the car with the pump dry or you will damage it.

Merdock777 - The power steering system uses ATF. ATF is a hydraulic fluid.

Yes, use a little common sense and turn off the car.

Just use the turkey baster 3X times and you have 95% new PS fluid. Just drive a few milles between each time. I like the baster method because I don't like undoing any oil lines unless absolutly necessary because of the potential for leaks. I ALWAYS follow the manual so when it says ATF I use ATF. ed
