I would like to add to this thread. I recently had an engine replaced. The garage that did the work had and I assume has very poor mechanical ability. They never bled my power steering. MY SYSTEM HAD AN UNUSUAL LARGE AMOUNT OF AIR IN IT!!! Upon getting the system bled out and getting ALL THE AIR OUT, I learned about a great idea that Ford discontinued in 1997 on the entire Taurus lineup. This will give your power steering pump a much longer life!!!!!!!!
I have a2001 3.0 ohv
code U. You can use this procedure on any model I suspect.
My fluid was dark brown/black and foaming badly. The pump wined terrible but the shop owner said it would work its way out when driving. 45 miles later and pissed off I did the following.
The return hose coming off the pwr steering pump reservoir can be cut and clamped with a new TRANSMISSION INLINE FILTER if your GEN 4 wants cleaner fluid for longer!!!. You will have to find a good location on the line as the filter is about as large as an inline fuel filter canister. Ford sells these "Power Steering Fluid Inline Filters" for $60.00+ tax but it is listed in there computers as a Transmission Inline Filter after 1997!? TOO MUCH $$$. SEARCH FOR AN AFTER MARKET.
To completely remove all the air I left my engine OFF. Using LOTS of old rags I wrapped them around the Pwr Stg Punp cap, (with the cap OFF), and turned the key to unlock and began turning the wheel slowly left and right to the end stops. After each cycle of left to right I would remove the rags, Soaked with fluid. I fortunately had a buddy watch as all the air bubbles rose to the top and literally burped out of my system!!!! THIS WAS MUCH MORE EFFECTIVE THAN THE HAYNES MANUAL. After the air came out he fluid would then go lower replacing where the air had been in the system. After about 10 cycles I had very little fluid in the reservoir as it had bled down into the system. I then added more fluid up to the cold fill line and did the procedure a few more times. After there were no more bubbles I filled to cold line, replaced the cap and all is fine.
I then read in the Haynes Manual that there is an inline filter to replace but my year does not show one on any parts computer in any Ford Store or auto parts store.. I found out through many calls to auto part stores and Ford Parts Dept. of the filter being discontinued after 1997. WHY, WHY, WHY???. Advance Auto and the like do not offer any inline filters for pwr steering or tranny. Auto Zone said they used to sell an aftermarket inline tranny filter that would work but they have not gotten back to me.
I will update when I here from them or find one through a transmission shop.
