It is not like most cars that I have had where you simply pull off a hose and pull out the valve. It is inside a housing that you remove two bolts and take off the cover which has a heavy duty spring under it so take it off slowly. Then remove the spring and I used some needle-nose pliers to grab the nipple of the valve and it pulled right out. I then replaced it with a new valve and put it back together the same way I took it off.
For a detailed desrciption of how to replace with pics check out:
