front of the left front wheel house.
Each washer pump and motor unit has a barbed
nipple, which is installed through a rubber grommet
seal inserted in a hole near the bottom of the reser-
voir. The washer pumps are retained by an interfer-
ence fit between the barbed nipple and the grommet
seal, which is a light press fit.
The washer reservoir has a separate filler neck
and grommet seal. The filler neck snaps into the res-
ervoir from the engine compartment side of the left
inner fender shield. A snap-fit filler cap with an inte-
gral bail strap is fit to the reservoir filler neck. On
models so equipped, the reservoir also has a hole pro-
vided for a washer fluid level sensor.
The washer reservoir, filler neck, grommet seal,
and filler cap are each available for service.
