I'm doing my power steering pump tomorrow afternoon.  The instructions screamed at me to flush every ounce of the old fluid out (not just remove what's in the reservoir).

Is it really necessary to do this?  If so what's the best way to do it....

1)  Drain the reservoir
2)  With car off....Turn the wheel a couple times to force more fluid into the reservoir & drain
3)  Disconnect the two lines and turn the wheel a couple more times to drain the system completely
4)  Remove any fluid in the reservoir.

What am I missing?  Is this overkill and should I just drain what I can get out of the reservoir and go on with life?

Thx

The idea is to get debris out of the system to prevent failure of the new pump . A little work now or a lot later .

You know what I just realized that when I had the Rack and Pinion and the high pressure line replaced 2 months ago, they replaced the fluid.  So if the fluid is only 2 months old, I can probably leave what's in the lines.  Right?

It depends if it threw a bunch of metal into your fluid when it went out.  

I had metal from a bad power steering pump ruin my rack and pinion.  Granted it was whining for quite a while before I changed it, so mostly my fault.

They make aftermarket inline filters specifically for power steering systems. Not very expensive and pretty easy to install, will catch the debris left in the system and protect the whole thing.

Yep, I am already on it.  Planning to buy it.

I assume we would have to be installed on the low pressure line.

Make sure to elevate the front wheels after the flush, refill and first time turning the steering wheel. There will be some air in the system.

I would just run 3 or 4 quarts of tranny fluid through the system and into a bucket. Make sure you get all of the debris out of the system.



I built power steering pumps for 15 years and this is how we did it in the service bay.




4 qts of transmission fluid is really cheap compared to the cost of another pump or rack.
