Replacing power steering fluid?

2005 4.2L v6. Is there a drain that I can't see to flush out the old fluid and replace it with new? Do I have to siphon the old stuff out? Please help.

There is no drain, and there are several methods for changing the fluid, if it needs it. Just siphoning whats in the resorvoir, and changing that wont get it all. Heres a simple way to do it, and flush the whole system. Take the return line off the resorvoir, on most thats the rubber line that attaches with a clamp. If it has two lines, itll be the smaller one, not sure exactly what that setup looks like. Hook a hose to this line and run it into a clear container. Put a vacum cap over the fitting it came off of. Take the belt off, so you can turn the power steering pump by hand. Turn the pump till the resorvoir gets low, and keep it full, so you dont get air in the system. You can wrap a string around the pulley to speed things up a little if you want, but it really doesnt take long. One revolution of the pump will pump 1/2 to 1 oz. Do this till you get fresh fluid coming out, hook the lines up, and youre done.
