Shipping may bring it up to AutoZone's price; I didn't check that.
I cleaned the one on my Escape a while back and it has worked OK so far
(knock on wood). I used WD-40 and an old toothbrush, and rinsed it well (
with WD-40) before putting it back on. You can move the plunger back and
forth fairly easily when clean. Don't use alcohol- it dries the rubber
parts, causing to crack.
Good luck!
