Check Valve: Description and Operation
Front Washer Check Valve - Description
FRONT
The front check valve (2) is standard equipment on this vehicle, and is located in the engine compartment in the washer supply hose on the underside of
the hood panel just outboard of the front washer nozzle. The check valve consists of a molded plastic valve body with a raised arrowhead (4) molded
into its center section indicating the direction of the flow through the valve. A barbed hose nipple (1 and 3) is formed on each side of the raised center
section of the valve body. Within the check valve body, a small diaphragm is held against the lip of an integral sump well by a small plastic piston and a
coiled spring.
The front check valve cannot be adjusted or repaired and, if ineffective or damaged, it must be replaced.
