Check Valve: Description and Operation
Washer Check Valve - Description
DESCRIPTION
The rear check valve (2) connects the liftgate washer hose to the headliner washer hose and is located near the upper liftgate opening header behind the
right D-pillar trim panel within the passenger compartment. 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 rear check valve cannot be adjusted or repaired and, if ineffective or damaged, it must be replaced.
