Oops! Wrong Fluid!—Follow-Up—HELP!
Hello and Thankyou for the previous help, but I am in need of more.
I need to know the easiest way to get the BRAKE/CLUTCH fluid out of my POWER STEERING unit. The '94 is on ramps. I couldn't get far enough under the car — probably because of my stomach & I didn't think it would be necessary. From the passenger top-side, I could see
2 rubber hoses—one, that I did not know where it went & the other
clamped to metal tubing/conduit that seem to pass thru a cooling unit
going to the drivers side and into the steering gear box. I could not get
to either one of the clamped hoses. QUESTION: would the "other" hose be a hose that returns the fluid to the reservoir? If so, wouldn't that be the hose to disconnect—after the fluid has passed thru the entire system? Does it have to pass thru the entire system to be flushed entirely. PLEASE NOTE: The "bad" fluid has been in the car
going on 3 days. Should I be overly concerned? Can it hold until the
weekend? ADVICE NEEDED. Thanks Again.

As long as you still haven't cranked the engine, you might be OK. I would just vacume it outwithvacume-pump or eventhe turkey baster ASAP. Fill it with new fluid and crankitup for just a minute. Kill engine and suck it out again, refill and repeat 3-4 times at least (just let the ngine run a little longer each time). After changing it the first three times I would turn the streeing wheel 'lock to Lock' acouple of times for the last couple of changes.
You need to get that out ASAP, though.

It isn't as bad as you think, since you did use a hydraulic fluid.
The hose under the resevoir is the pump suction intake (low pressure LP hose). The pump pressure line connects to the rack with special high pressure fittings (this is the only high pressure line that you;re not going to touch). The exhaust from the rack is a LP hose that connects to the cooler. There is a LP hose from the cooler that connects to the side of the resevoir.
You want to disconnect the lp pump suction hose from the bottom of the resevoir to drain the resevoir and then reconnect.
Next disconnect the return lp hose that connects to the side of the resevoir at the connection to the cooler.
Plug the hose end that returns to the resevoir and place a 3/8" rubber hose on the end of the cooler and set up to discharge into an oil collection pan on the floor.
Filll the resevoir with new fluid.
Have someone start your engine while you keep adding fluid to the resevoir. Have your assistantr turn the steering wheel all the way left then all the way right to flush out the old fluid until you see clear fluid, then have your assisitant turn off your engine.
Reconnect the temporarily plugged resevoir return hose back to the cooler.
Top off the reservoir to the correct level. Restart, turn rack to rack a couple of times then teurn off engine and top off fluid.
Have a beer and be proud of your work
