A single washer fluid reservoir is used for both the front and rear washer systems. See Fig 1. 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.
