2003 Vulcan has leak through cap on power steering pump. Any sugestions of cause of problem?[/b]
I have seen this problem reported frequently, and have experienced it myself. The symptom of spewing fluid out of the cap vent is usually caused by air in the system. I have bled mine on numerous occasions by slowly turning the wheels from lock to lock in a parking lot, but the problem returns eventually. I also see where fluid is added to to a low reservoir but overflows later as fluid is going into the boot and eventually comes back into the system and overflows. I also see where many have to replace the rack due to leaking into the boot. Or others who replace the pumpr due to excessive noise. Pump noise can be caused by air in the system also.
I ran across a very interesting post by someone with the same problem who found the cause to be a loose recessed nut with four holes inside the passenger boot. When the nut was tightened the air problem and fluid spewing went away. Fluid in the driver's can be the result of the same loose nut ont he passenger side as there is an equalizer tube between both sides.
I am wondering if anyone here has tried this fix, and/or how easy is it to reach the nut to check it and a good tool to use.
here is an excerpt from the thread and a link below .... thoughts ??

I think I may have good news for the majority of you with Taurus' and Sables' that have power steering bubbling/ spewing issues. My wife and I own both of these cars both 1999 models. 1st my sable started with the bubbling of the power steering fluid and it spewing out of the weep hole on the cap. I tried bleeding it repeatedly with the same end result. I finally decided to save the money wasted on power steering fluid and drive without it. Till one day, I was expecting a flooring delivery in the A.M. hours that did not arrive until 5:30 pm, the exact time that I needed to leave to pick up my daughter. My wife had to drive the car. I had to put plastic under the cap so that she would have power steering at least as long as it took for her to pick her up and get back home. It worked with bad results (at least I thought bad results). As soon as she got back there was a pop and power steering fluid leaking like it was being poured on the ground. I realized it was leaking from the rack on the passenger’s side. I removed the boot and saw that an internal nut had work its way out. This nut has 4 holes that apparently are used to screw the nut in place. No one at the auto stores seemed to know what the tools was, so I had to improvise. I purchased A very long screwdriver (I THINK 2 FEET) I taped a pipe to the screwdriver to give it more stiffness. (I used the pipe from my hydraulic jack) I worked the nut back in through the wheel well. Once I was done I had power steering NO MORE BUBBLING OR SPEWING!
Fast forward about a year, we purchased the Taurus for my wife and after about 8 months the same bubbling and spewing began. I added fluid that never leaked onto the ground. I again thought it was a bleeding issue. I kept bleeding by turning the wheel left to right and adding fluid as the level dropped. I thought I had it when...POP, the boot slit, power steering fluid was leaking from the rack BUT this time on the driver’s side. I removed the boot hoping to see the same internal bolt... But to my dismay no! The set up was totally different. I could not tell where the fluid was coming from, until I saw this small metal tube dripping slowly. I followed it and realized it went to the passengers side boot. Upon removing the boot I checked that infamous internal bolt and IT WAS LOOSE! After working it back in... You guessed it... no more bubbling or SPEWING!
I surmise that the bubbling is a direct result of that internal bolt being loosed causing air to be sucked into the system. Case Solved! Thank God!

My husband and his friend, who used to be a mechanic spent hours trying to figure out what was wrong with my power steering pump. I searched on-line, found your info, and gave it to them. They were skeptical at first, but you were dead on correct. This fix saves both time, and lots of money. I think you may have right and left reversed in the fix, but the bolt was loose, and after being tightened, it doesn't spray/spout any more fluid. Thank you so much!!!

Regarding the steering problem with the 99 Ford Taurus, I would like to thank the person who wrote about tightening the nut on the rack assembly (passenger side). The car belongs to my sister and she was given a quote of $1300 to replace the rack and power steering pump. Based on the entry from this site, I was able to remove the boot, tighten the nut (using the needle nose pliers and a great deal of patience), and then turned the wheels back and forth a couple times to expel the oil that had filled the drivers side boot (and to make sure no more oil leaked out). Note that this boot gets filled because of the equalizing vent line between boots. I put the boot back on and the steering problem is 100X better, but not 100%. I would also like to thank the operator of this site for enabling the sharing of this kind of experience.[/b]
Are people replacing racks unnecessarily ? I see some on threads have replaced their racks and pumps more than once
This may not be the solution for all. But I have bled my system and it has been fine for a while, but eventually air comes back in the system.
