My '06 had the dreaded power steering pump failure that occurred after the warranty expired. I got the pump for $123 at O'Reilly Auto Parts and bought 4 pints of Honda Power Steering Fluid from the dealer ($23). The project took about 3 1/2 hours and that was with me going slowly and not rushing anything.
The new pump had non Honda fluid inside (factory testing?) so I purged it and primed it with Honda fluid while chucked up in the bench vise. My procedure was similar to this user's post:
The process had no surprises other than getting used to the tight confines of the engine compartment. Three things will make your replacement easier:
1. use a rope or ratcheting strap to hold the hood in a vertical position (way past prop-rod position) via a roof rack rail. This gets the hood way up out of your way and prevents the prop rod from interfering while you work.
2. Completely remove the reservoir. Its absence, along with the pump supply hose frees up a lot of space for working.
3. Definitely remove the pulley as the other user's thread suggests. This also makes removal of the pump easier due to the tight confines.
Post a reply if you are going to undertake this project and I will email you a PDF scan of the factory service/repair manual for this procedure.
