I have a 2004 Honda Accord. It is foaming orange stuff. The fluid should be clear?? Took it to a shop, they flushed the system, said they had to do it 3 times, said there were no leaks in the lines and the pump was working fine. Said they got most of the orange stuff out, but theres still a tinge of it, but its mostly clear again. Felt better driving it after the flush. Started it up this morning, made the same whining noise as before, worse when you move wheel back and forth. Looked in the reservior, orange and foaming again. Sigh. Any ideas??
The 'foaming' you describe is almost certainly air getting into the system. The power steering pump will cause a suction effect in the pump and then pressurise the system. Look for loose hose clips, damaged piping, and leaking seals on the pump body between the pump and its fluid reservoir.
