Self leveling: NO
Head lamp washer: Not really but, you'll get your pants wet.
First, wrap some cardboard around the lamp washer hose and squeez it with small vise-grips, so you don't lose all your W/W.
With a small screw driver pry the lamp washer out a bit (be very gentle or you'll crack the flimsy painted cover) and when you can, fit your fingers behind it and pull it out. Once you did that you'll see how it's made like a -T- at the end. Grabe both sides of the T's bar and yank it out. It's just clipped in. When you do that the rest of the washer nozzle wile slide back and spit what's left of W/W on your pants.
Once that's done you have two screws on top of the headlamp and two others that are lower behinf the rad. support. you then just slide the lamp out.
