WASHER RESERVOIR
DESCRIPTION
A single washer fluid reservoir (2) 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 (1) 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 (4), and another dedicated hole inboard of the pump for the washer fluid level switch (6).
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 (3) 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 (5) that engages in
a slot in the right front frame rail. A blind rivet secures the reservoir filler neck bracket to the upper radiator cross-
member 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 inoperative 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.
OPERATION
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.
