![]() What's the best way to change my power steering fluid. (1989 Mustang 5.0LX, 120,00 miles)
The fluid is old and dark (power steering works good, no noise) but I'd like to change it for good measure. The car had a new (leaking) pump installed but they didn't change the fluid. I tried draining and refilling the resevior but it's still pretty dark. Is it okay to disconnect the low pressure hose and crank the engine. Will doing this suck the old fluid out of the rack? Any help would be appreciated! Thanks, Phil |

![]() Yeah, I think the idea you have about the disconnecting the low pressure hose will work. Just don't let it run dry for more than several seconds. Don't wanna screw up the pump.
Or, I guess you could just get a rubber bulb and pull it out OR stuff a big rag down in there and soak up as much as possible. Then add new fluid run car (while turning steering wheel from side to side) a few minutes and then soak that stuff out and repeat till it's clear enough for ya. ![]()

![]() Yep exactly, use the low pressure (screwclamp) side.
What I do is plug that end of the pump, and point the hose into a bucket. Empty most of the reservoir, the stuff that just spilled all over the floor.... ![]() Then without starting, crank the motor, and add new fluid into reservoir. This pumps (one-way) fluid thru the system, and flushes it. Put the hose back on, and top off reservoir. CRANK steering lock to lock to remove air bubbles, and top off reservoir.
