Windshield Washer Hose: Description and Operation
Description
DESCRIPTION
The washer plumbing consists of a small diameter rubber reservoir washer hose that is routed from the barbed outlet nipple of the electric washer
pump/motor unit on the washer reservoir through a trough molded into the back of the reservoir above the washer pump to the engine compartment
washer hose to the right side of the engine cooling module. On vehicles equipped with an optional diesel engine, the reservoir washer hose is routed
through routing clips on the top of the radiator fan shroud from the washer reservoir on the left side of the radiator to the engine compartment washer
hose on the right side of the radiator.
The engine compartment washer hose is contained within the right headlamp and dash wire harness (2), which is routed through the engine compartment
along the top of the right front fender wheel house to the dash panel. This hose is connected to the washer reservoir washer hose at one end (5) and to the
cowl plenum washer hose at the other end (3) with molded plastic in-line fittings that have a barbed nipple on each end.
The cowl plenum washer hose (4) is routed from the engine compartment into the cowl plenum area through a trough formation located near the right
end of the cowl plenum cover/grille panel. The cowl plenum washer hose is connected to the washer system check valve/Y fitting on the underside of the
cowl plenum cover/grille panel. The cowl plenum washer hose and the two washer nozzle hoses are routed through integral routing clips on the
underside of the cowl plenum cover/grille panel. The cowl plenum washer hose is connected to one nipple on the Y fitting and the two washer nozzle
hoses are connected to the other two nipples. The washer nozzle hoses are then routed along the underside of the cowl plenum cover/grille panel to the
two washer nozzles.
Washer hose is available for service only as roll stock, which must then be cut to length. The molded plastic washer hose fittings cannot be repaired. If
these fittings are ineffective or damaged, they must be replaced.
