Yeah, I just changed out my tranny fluid in my '90 with valvoline maxlife.. OOhh what a difference that made. But anyway, I decided to go at the muddy power steering fluid.. so I vacuumed out all the fluid started her up did the move lock to lock, then I vacuumed up everything that came into resevoir and again went lock to lock until no fluid would come up. I then proceeded to add close to a quart, which is the capacity, of valvoline maxlife power steering fluid. Then I started her up let her suck that up and went lock to lock until it quited down a bit, I think it will take a while to get all the air out of there, but I can tell already the difference of having clean fluid in there.
