Be careful NOT to overpressure the system. In my case, all I had to do was push the rubber connections further on, and change the o-rings (which you've all ready done), all of which were leaking. Pressuring the system up to about 2 PSI, I was able to find the leaking parts. Then I inserted the valve through the center of the wine cork, so that the rubber (with the cork core) would seal the power steering reservoir opening, and I could pressure the system through the valve, which was now sticking out of the top of the wine cork. Did you try pressuring up the system and looking for leaks? I did this: I cut a bicycle tire tube such that the presta valve was preserved, and the was enough tube rubber left to wrap around the outside of a wine cork. Unfortunately, the leak can be small enough to let air in, but not let fluid out, making it very hard to find. As you may know, this system runs under a vacuum, and the fast flowing fluid will create an even stronger vacuum, pulling air in. Sounds like you've done some great troubleshooting. I did not see this test in that procedure, so.ĭisclaimer: I am NOT an expert. This is what I did - I can't guarantee it will work for you (try at your own risk). Like the procedure you mentioned, I need to start this with. I can replace the hose from reservoir to pump easy enough, but the others probably not.Īny thoughts on the foaming coming out of the high pressure hose? That disappears behind the engine, and I might take it to my mechanic to replace. 'Foaming Fluid' in a PS pump is indicative of an over filled reservoir, a low reservoir, or in the case of rack and pinion steering, a 'blow-by' in the reserculating valve. We did not see dirt or trash on the reservoir screen, but could it be clogged? How could the reservoir otherwise en-train air? Would the hose into the reservoir en-train air and foam the oil? I would think not? I read through this thread after searching on this problem. Turn the wheel stop to stop, and crank the engine, repeating, thinking there is air in the system that needs to work itself out. My attempts to recover, after putting it back together, was to use a turkey baster to pull the fluid out, and put fresh fluid in. it does not seem to be doing that now, 3) with the car off, turning stop to stop, i get creaking or crackling - maybe that is normal and not an indicator, 4) the fluid in the reservoir was dark. I observed a few things: 1) the reservoir is foaming, 2) foam was coming out of the high pressure hose above the pump at first. I cranked the car and turned the wheel from stop to stop. I Got the o-rings in, cleaned, replaced, and refilled the reservoir. I had towels and rags down, but it was still a mess. This resulted in oil being blown out of hose that feeds the reservoir. I replaced the low pressure and high pressure hose o-rings.ĭuring the job, with the low pressure hose and reservoir removed, the car was accidentally cranked and ran for a couple of seconds. My 2001 Odyssey had a steering whine that was characteristic of a leak on the low pressure/suction side.
