Key Features:

• Factory replacement check valve ensures reliable windshield washer operation

What It Does:

This check valve is a critical component in the windshield washer system. When functioning properly, it keeps washer fluid in the delivery lines after use, ensuring immediate spray when you activate the washers. A failed check valve can cause symptoms like delayed fluid delivery, weak spray patterns, reduced pressure, or fluid leaking from the valve itself. The valve uses an internal rubber diaphragm that allows fluid to flow in one direction while sealing to prevent backflow.
