Changing the power steering fluid

If it 's brown and burnt smelling then yes , I've heard it shouldn't be " purged " but if you draw out what is in the reservoir the new will mix with the old crap still in the lines , if you do the math it'll take multiple times to get near a majority of it new ., I guess you can pull a line and get all you can but running it dry probably isn't a good idea . That's what I think . I would use honda fluid .

At 188K, I would drain and refill.

Thanks for your responses.
