The cap for the windshield washer tank on my Jeep JK has started to leak fluid over the last couple of years. The cap itself was in good condition, but the foam seal underneath had become brittle and had curled up from the exposer to the chemical in the washer fluid. This would cause the tank to leak fluid if I hit a good bump in the road, or if I was off camber on the trails. I was also concerned that the foam seal would fall down inside the washer tank and get debris clogged into the washer pump. So it was time to replace it with a new cap. I did check the dealership and seeing that they practically wanted a left kidney for a new cap, I check Amazon for a Dorman and found the same cap for much less.
The windshield washer tank cap on my JK would leak fluid everytime I hit a good bump, or was off camber while wheeling. Never enough to drain a tank, but just enough to leave residue and streaks on top of the tank. The cap itself was in good condition, but the foam seal underneath was loose, brittle and crumbling away after many years.
Installation:
Removal of the old cap and installation of the new is very simple. Open the cap and then pull forward on the base where it is hinged underneath a plastic hook attached to the washer tank. It should come out fairly easy, you shouldn't have to pry on the cap at all to get it out. Reinstall the new cap the same way.
