When it comes to Power Steering, I admit, I've never flushed it, but once in a while, I will take a cheap turkey baster, pull all the fluid out of the res and re-fill with clean fluid. I know it's not a "flush", but it's at least a cycle of some fresh fluid.

 

I've changed my PS fluid the same way using a small hand pump. Did it 3 times over the course of a week. Figured it at least helped the fluid situation.

 

I finally got the Monte fixed! I had a day that the weather finally cooperated with me. I didn't like what I saw when I sucked the extra power steering fluid out though. There was chunks of dirt all through it The new engine mount bracket went smooth though. Hopefully the other one won't break now lol.
