Windshield Washer Hose: Description and Operation
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 combination washer reservoir/coolant reserve bottle through a trough molded into the outboard side of the reservoir/bottle unit
above the washer pump to the engine compartment washer hose (2) The engine compartment washer hose is secured in routing clips located along the
length of the headlamp and dash wire harness (2), which is routed through the engine compartment along the top of the right front inner fender shield (1)
from the headlamp support to the dash panel. This hose is connected to the washer reservoir washer hose with a molded plastic in-line fitting that has a
barbed nipple on each end.
The engine compartment washer hose passes through a hole protected with a rubber grommet (3) in the right side of the cowl plenum panel. In the cowl
plenum the engine compartment hose is connected to the cowl plenum washer hose by another molded plastic in-line fitting. The cowl plenum washer
hose is connected to the washer system check valve/wire 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 wire 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 faulty or damaged, they must be replaced.
Washer fluid in the washer reservoir is pressurized and fed by the washer pump/motor unit through the washer system plumbing and fittings to the two
washer nozzles. Whenever routing the washer hose or a wire harness containing a washer hose, it must be routed away from hot, sharp, or moving parts;
and, sharp bends that might pinch the hose must be avoided.
