Check Valve: Description and Operation
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.
