Someone stopped by the shop today with a problem with the power steering leaking. I checked it out and the return line from the rack to the pump is rusted through and needs to be replaced. The pressure line looks just as bad and will develop a leak soon too, if not replaced.
While chatting the customer revealed that while stuck with no power steering, he put motor oil into the reserve tank because that’s all he had. It did get him home.
My plan is to replace the pressure line first, then cut the return line below the car (where it can be accessed better). Then use my evacuator,
hooked to the return line from the rack. Start the siphoning and fill the reserve tank with the proper fluid to flush everything out.
I figured that it would flush the reserve tank, pump, pressure line, and rack. Then replace the return line and top off the tank.
What are your thoughts. Will I have to have the engine running while I flush, and do I need to work the steering wheel left and right too.
