This is a 3-way windshield washer check valve that controls the flow of washer fluid to the windshield nozzles. It ensures fluid is directed correctly and prevents backflow, maintaining proper system pressure. A worn valve may cause weak or erratic spray patterns, or washer fluid to drain back into the reservoir, leading to delayed spray when activated.
Always verify with serial number before ordering.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
Weak or inconsistent spray from one or more washer nozzles is the first sign. If ignored, the spray may become intermittent or cease altogether, reducing visibility in inclement weather. Ultimately, the system may fail to deliver fluid when needed, compromising driver safety.
Ensure all fluid lines are clean and free of debris before connecting them to the new valve. Avoid forcing connections, as this can damage the valve's ports.
Inspect the washer fluid pump and nozzles for proper operation and any signs of clogging or wear when replacing the check valve.
