Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
CHECK VALVE, Washer: 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.
