Over the weekend I pulled my 2000 Odyssey up on ramps and replaced the AC compressor. To get the compressor in, I had to push past the power steering fluid resevoir several times while removing the alternator and old compressor. When I completed the job and started to back down the ramps, I had a new noise that was not there before changing the compressor. I could hear the whine that a power steering system makes when it is low on fluid. I stopped quickly and discovered that the power steering resevoir had fluid foaming and bubbling out the top of the reservoir. There was no problem with the power steering when I started the compressor change out. Visual inspection did not reveal any damaged lines or kinked power steering hoses. Is there any likely cause for the new problem? Thanks in advance for any suggestions.
