2003 Honda CRV How do I replace power steering pump on a 20

Its easily done but hard to explain, there is a nut on a long thread which is your adjuster, you need to loosen this, and loosen all the bolts holding the pump to the engine. Look on the internet for a workshop repair manual. But if you dont know much about the car your probly better off getting someone who knows how to do it to do it.
