Windshield Washer Hose: Description and Operation
HOSE-WINDSHIELD WASHERDESCRIPTION
FRONT
The front washer plumbing consists of a small diameter rubber hose (6) or hard plastic tubing that is routed along with the rear washer plumbing (4) from the washer reservoir (1) located at the left front corner of the engine compartment. Both hoses or tubes are attached to their respective front or rear outlet nipple of the washer pump/motor unit (2) near the bottom of the reservoir. The hoses are then secured by three plastic push-in type retainers (3) to the left side sheet metal within the engine compartment to the left side of the dash panel (11).
From the dash panel, the two washer hoses or tubes are routed separately. The front hose or tube is routed up toward the hood (10), while the rear hose or tube is routed through a grommet and a hole (5) in the dash panel into the passenger compartment. The front hose or tube is secured to the left side of the inner hood panel reinforcement by a plastic push-in type retainer (7). Two plastic in-line fittings and a molded rubber tee (8) provide the take out for the left washer nozzle, and a plastic in-line fitting with a molded rubber elbow (9) terminate and connect the front hose or tube at the right washer nozzle.
Washer hose or tube 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.
REAR
The rear washer plumbing consists of a small diameter rubber hose or hard plastic tube that is routed along with the front washer plumbing from the washer reservoir under the left front fender ahead of the left front wheel to the engine compartment. Both hoses or tubes are attached to their respective front or rear outlet nipple of the washer pump/motor unit near the bottom of the reservoir. The hoses or tubes are then secured by retainers to the left inner fender. Just forward of the dash panel (3) in the engine compartment, an in-line connector with barbed nipples joins the rear washer reservoir hose (1) or tube to the A-pillar hose or tube (2).
The A-pillar hose or tube (1) passes through a hole with a rubber grommet (2) in the dash panel (3) into the passenger compartment where it is attached to the A-pillar (4) with plastic retainers (6). The A-pillar hose or tube is then routed up the left A-pillar to the headliner. At the headliner, an in-line connector joins the A-pillar hose or tube to the headliner hose or tube (5).
The headliner hose or tube is routed above the headliner and along the left roof side rail to the rear of the vehicle. At the rear of the vehicle, the headliner hose or tube is routed above the headliner and along the upper liftgate opening panel toward the right side of the vehicle. The headliner hose or tube then passes through a hole with a rubber grommet in the upper liftgate opening panel and through another hole with a rubber grommet into the upper inner liftgate panel to the rear washer nozzle.
Washer hose or tubing is available for service only as roll stock, which must then be cut to length. The headliner washer hose or tube is integral to the headliner and, if ineffective or damaged, the headliner unit must be replaced. The molded plastic washer hose fittings and routing clips cannot be repaired. If these fittings or clips are ineffective or damaged, they must be replaced.
OPERATION
FRONT
Washer fluid in the washer reservoir is pressurized and fed by the washer pump/motor unit through the front washer system plumbing and fittings to the two front 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.
REAR
Washer fluid in the washer reservoir is pressurized and fed by the washer pump/motor unit through the rear washer system plumbing and fittings to the rear washer nozzle located on the Center High-Mounted Stop Lamp (CHMSL) on the top of the liftgate outer panel. 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, any sharp bends that might pinch the hose must be avoided.
