Dodge Ram Truck 1500-2500-3500. Manual — part 606

A round bright yellow plastic cap (2) with a rubber seal snaps over the open end of the washer reservoir filler neck
and can be easily distinguished from the coolant overflow bottle cap (3) by an International Control and Display
Symbol icon for “Windshield Washer” and the text “Washer Fluid Only” molded into it. The cap hinges on and is
secured to a molded-in hook formation on the top of the reservoir just behind the filler neck when it is removed for
inspecting or adjusting the fluid level in the reservoir.

Except on SRT-10 and diesel models, the washer reservoir is secured to the cooling module radiator shroud with
two integral tabs at the bottom, and through two integral mounting brackets with two screws at the top. The two
bottom tabs are inserted into two slots near the bottom of the shroud, while the two screws secure the mounting
brackets to integral mounting points near the top of the shroud. On SRT-10 and diesel models, the washer reservoir
is secured with two screws through integral mounting brackets to the left vertical member of the radiator support.

There are separate, dedicated holes on the lower rearward facing side of either reservoir provided for the mounting
of the washer/pump motor unit (6) and the washer fluid level switch (5). A snap post receptacle for the washer pump
and a routing trough for the washer hose are molded into both reservoirs to allow for mounting of the washer pump/
motor unit without the use of fasteners.

Except on SRT-10 and diesel models, the washer reservoir is serviced only as a unit with the engine coolant
reserve bottle. A washer reservoir cannot be repaired and, if faulty or damaged, the unit must be replaced. The
washer pump/motor unit, the washer fluid level switch, their rubber grommet seals, as well as the reservoir 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 washer system. 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 bottom 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 fluid level switch
is mounted just above the washer pump inlet nipple in the sump area of the reservoir so that there will be adequate
warning to the vehicle operator that the washer fluid level is low, well before the washer system will no longer
operate.

REMOVAL

EXCEPT SRT-10 OR DIESEL ENGINE

1. Unlatch and open the hood.

2. Disconnect and isolate the battery negative cable.

3. Disconnect the coolant overflow hose (3) from the

CONTAINER - REMOVAL).

4. Disconnect the reservoir washer hose (4) from the

barbed nipple of the inline fitting at the engine com-
partment washer hose in the right headlamp and
dash wire harness and allow the washer fluid to
drain from the reservoir into a clean container for
reuse.

5. Disconnect the right headlamp and dash wire har-

ness connector for the washer fluid level switch
from the switch connector receptacle (5).

6. Disconnect the right headlamp and dash wire har-

ness connector for the washer pump/motor unit
from the motor connector receptacle (7).

7. Remove the two screws (2) that secure the reservoir mounting brackets to the top of the radiator shroud.

8. Grasp the bottom of the washer reservoir (1) firmly with both hands and pull the unit sharply upward to disen-

gage the locking feature on the washer reservoir from the depression in the radiator shroud.

WIPER ARM

DESCRIPTION

The wiper arms are the rigid members located
between the wiper pivots protruding from the cowl ple-
num cover/grille panel near the base of the windshield
and the wiper blades on the windshield glass. These
wiper arms feature an over-center hinge that allows
easy access to the windshield glass for cleaning.

The wiper arms each have a die cast metal pivot end
(3) with a large internally serrated socket formation at
one end. A key (4) within the socket formation indexes
the wiper arm to a keyway in the pivot shaft to provide
wiper alignment, and a spring-loaded latch (5) on the
underside of the pivot end locks the unit to the pivot
shaft when it is fully installed. The right and left wiper
arms for this model are not interchangeable, as the
right wiper arm is slightly longer than the left one.

The wide end of a tapered, stamped steel channel (8) hinges on and is secured with a hinge pin (6) to the blade
end of both the right and left wiper arm pivot ends. One end of a long, rigid, stamped steel strap (2), with a small
hole near its pivot end, is riveted and crimped within the narrow end of the stamped steel channel. The tip of the
wiper blade end of this strap is bent back under itself to form a small hook (1). Concealed within the stamped steel
channel, one end of a long spring (7) is engaged with a wire hook on the underside of the die cast pivot end, while
the other end of the spring is hooked through the small hole in the steel strap. The entire wiper arm has a satin
black finish applied to all of its visible surfaces.

A wiper arm cannot be adjusted or repaired. If damaged or faulty, the entire wiper arm unit must be replaced.
