Windshield Washer Reservoir: Description and Operation
Washer Reservoir
A single washer fluid reservoir is used for both the front and rear washer systems. The molded plastic washer fluid reservoir is mounted on the outboard
side of the right front frame rail in front of the right front wheel, where it is concealed by the right front wheel house splash shield. The only visible
component of the washer reservoir is the filler neck and cap unit, which extends through a hole in the right front wheel house extension panel into the
engine compartment. A bright yellow plastic filler cap with an integral bail strap and filler neck mounting bracket is labeled with an International Control
and Display Symbol icon for "Windshield Washer." The cap snaps over the open end of the filler neck.
There is a dedicated hole in the top of a ledge-like sump area of the reservoir provided for the mounting of the washer pump/motor unit, and another
dedicated hole inboard of the pump for the washer fluid level switch. A receptacle molded into the reservoir allows for mounting of the washer pump
without the use of fasteners. The reservoir also features an integral rear hose routing trough on its outboard side. The washer reservoir is secured to the
outboard side of the right front frame rail by two screws and an integral molded hook tab that engages in a slot in the right front frame rail. A blind rivet
secures the reservoir filler neck bracket to the upper radiator crossmember in the front of the engine compartment. The forward end of the right front
fender wheel house splash shield must be removed to access the washer reservoir for service.
The washer reservoir cannot be repaired and, if faulty or damaged, it must be replaced. The washer reservoir, the grommet seal/filter screen for the
washer pump/motor unit, the grommet seal for washer fluid level switch, and the filler cap are each available for individual service replacement.
The washer fluid reservoir provides a secure, on-vehicle storage location for a large reserve of washer fluid for operation of the front and rear washer
systems. The washer reservoir filler neck provides a clearly marked and readily accessible point from which to add washer fluid to the reservoir. The
washer/pump motor unit is located in a sump area near the front of the reservoir to be certain that washer fluid will be available to the pump as the fluid
level in the reservoir becomes depleted. The washer pump/motor unit is mounted above the lowest position in the sump. The washer fluid level switch is
mounted just above the sump area of the reservoir so that there will be adequate warning to the vehicle operator that the washer fluid level is low, before
the washer system will no longer operate.
