430 Drain Power Steering Fluid

I remember doing that years ago. Complete PITA as you’re figuring out. From what I remember I had to remove various hoses around it. Not something I’d want to do again.

 

I think there a better way at the PS reservoir. I'm about to do this (prob this week) and this is the method I'm going to try.

here is a video of the procedure on a different car, but the physics/mechanics are the same.

 

The WSM says to turn lock to lock to pump out the old fluid. Refilling along the way isn't that critical since the system self bleeds. You could disconnect at most any point along the return line and add a hose & container as long as the level in the container isn't above the top of the PS reservoir. It would then flow from there through the reservoir, clearing out the rest of the return line.

I have done it and it isn't hard. I believe we tend to overthink it.

I put a procedure on how to do this on here a few weeks ago, an easy diy job.

 

You disconnect the return at the tank and then fit an extension pipe so you can drop the fluid into a container, the pump draws from the tank so no point connecting to it. The rack does the pumping.

 

I did it at the rack. Open the bottom panel and you are off to the races

 

Will doing it at the rack flush the system, if the return goes to the tank you are sure it is getting the full circuit, unless the connection at the rack is the other end of the return line

 

It is per the WSM and yes, it is the other end of the return. When you remove it it drains the tank.

 

You sure you have the right one as i would have expected the return to go to the top of the tank

 

Per the WSM but do as you please.
