Hi. Glad I could help someone!! Do you KNOW you have the correct pump? There are two of them. Yes, just take off the wheel, and if you know how to remove the inner fender-well plastic, you get full access to the washer reservoir, and the 2 pumps are attached to it. They just unscrew and pull off the reservoir, or you remove the reservoir and the pumps are on the back side of it, pull off the line to the rear window, make sure it doesnt have any tiny holes in it, might as inspect it, to see how good it is, then put it back together and thats it.

PLEASE let me know how you get the inner fender-well plastics off, if you have a way to take some pics. of the plugs/screws that holds it in, post how to take them out. I thought you had to buy new ones from the dealer. BUT I am probably wrong. That once you push in on those plug screws, they have to be replaced. I know they are cheap...but they probably can be used over and over.
