Can't help you on that one Matt. I didn't remove the hood nozzles, I simply cleaned them out using as straight pin. Perfect size to clean out the crusty build up AND for adjusting the aiming point. The headlight wiper nozzles are held in with a phillips head screw. Be careful if you decide to pull them, the nozzles also hold down one end of the wiper arm spring. As soon as you remove the nozzle the spring will pop off, not difficult to replace if you have a small set of needle nose and some patience.
Again, for the headlight nozzles I used the straight pin again, plus blew through them the reverse of the water flow to clear. Also used the pin to adjust the aiming point of the headlight nozzles.
I probably used close to 2 gallons of water to clean and adjust both sets of nozzles.
