Easy Method To Change Power Steering Fluid

I used an easy, very clean, non-messy method to change my GT’s power steering fluid. So when I say all fluids have been changed, all fluids really have been changed.

I fabricated a fluid tank that fits on top of the GT power steering reservoir, see pic. This was made from PVC plumbing parts laying around the house or sourced from Lowes. I purchased a ZF power steering cap for about $5.00, which I drilled and tapped to fit a plastic ½” nipple. I plugged the ZF cap vent.

In operation, the power steering fluid runs from the reservoir, to the pump, to the steering rack, through the cooler and then back to the reservoir. I disconnected the driver’s side power steering hose from the power steering cooler, see pic. This hose is from the steering rack. I connected drain hoses to both the now disconnected hose and the cooler. The reservoir gravity drained very, very slowly through the drain hose connected to the cooler. When the oil quit draining, I refilled the reservoir with new fluid, about ½ quart. I let this drain again through the cooler, flushing the line with new fluid. When it quit draining this second time, I plugged the cooler drain hose. I clamped the drain hose from the rack into a 5 gallon bucket, see pic. I attached the fabricated PVC tank to the top of the reservoir, see pic. I poured 2-1/2 quarts of new fluid into the tank. I started the car and turned the steering wheel lock to lock a few times until the tank ran dry. Then I turned the car off preferably before the reservoir ran dry. Doing this, flushed new fluid through the pump and internals of the rack. I removed the tank, connected the rack hose back onto the cooler, filled the reservoir – DONE. Power steering fluid all flushed and replaced with new fluid - and no mess.

Nice, I assume where you connected to the cooler is the lowest point in the system?
