Front Check Valve: Description
Diaphragm-type washer system check valves are standard equipment in this vehicle. The check valves for the front washer system are integral to their respective washer nozzles (1). The check valve for the headlamp washer system, which is optional equipment only on vehicles manufactured for certain export markets, is integral to the headlamp washer hose tee fitting. The headlamp washer tee fitting is located behind the front fascia near the right headlamp washer nozzle.
Each diaphragm-type check valve consists of a molded plastic valve body where a small diaphragm is held against the lip of an integral sump well by a small plastic piston and a coiled spring.
The front and rear check valves cannot be adjusted or repaired and, if ineffective or damaged, the washer nozzle unit must replaced. The headlamp washer system tee fitting with the integral check valve also cannot be adjusted or repaired, and is serviced only as a unit with the headlamp washer hose assembly.
