RAM 2500 Truck 2WD V8-5.7L (2008)
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 Y 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 section that indicates the direction of the flow
through the valve, and three barbed hose nipples (1 and 3) formed in a Y configuration on the outside circumference of the center section of the valve
body. The check valve cannot be adjusted or repaired and, if ineffective or damaged, it must be replaced.
