Front Check Valve: Description
A single front washer system check valve is standard equipment on this model, and is installed in the front washer system plumbing. The front check valve is located in the engine compartment in the washer supply hose on the underside of the hood panel about 5 centimeters (2 inches) from the barbed nipple of the front washer nozzle. The check valve consists of a molded plastic valve body with a raised arrowhead molded into its center section that indicates the direction of the flow through the valve. A barbed hose nipple 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 faulty or damaged, it must be replaced.
