Windshield Washer Hose: Description and Operation

Fig. 2 Wye Fitting And Check Valve:

WASHER HOSES/TUBES
The washer plumbing consists of a small diameter rubber hose that is routed from the barbed outlet nipple of the washer pump/motor on the washer reservoir to a molded plastic in-line fitting with barbed nipples near the left end of the cowl plenum panel in the engine compartment. A second section of washer hose passes from the cowl plenum panel to the rear of the inner hood reinforcement, where the engine compartment hose is connected to one barbed nipple of a molded plastic wye fitting. The other two barbed nipples of the wye fitting joins the engine compartment hose to the two washer nozzle hoses. The two washer hoses are routed with locating clips along the underside of the hood 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 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.
