It is a bit of a challenge just due to access. you can remove the wiper arms, and the upper cowl trim to open it up a bit. There are three heater hoses and a vacuum line that attach to the valve. The original layout was spring type hosse clamps, usually those are replaced with a worm drive hose clamp.
