Check Valve: Description and Operation
A single washer system check valve is standard equipment on this vehicle, and is installed in the washer system plumbing. The check valve is integral to
the washer nozzle plumbing wye fitting (2) located in the cowl plenum area beneath the cowl plenum cover/grille panel near the base of the windshield.
The check valve consists of a molded plastic body with a raised arrowhead (4) molded into its center that indicates the direction of the flow through the
valve, and three barbed hose nipples (1 and 3) formed in a wye configuration on the outside circumference of the center of the valve body. The check
valve cannot be adjusted or repaired and, if ineffective or damaged, it must be replaced.
