Installation and Replacement

Ensure the vehicle's pneumatic system is fully depressurized before starting work. Disconnect the vehicle battery negative terminal.

Locate the original solenoid valve assembly. Note the exact position of pneumatic line connections and electrical connector orientation. Take reference photos if necessary.

Disconnect the electrical connector from the old solenoid valve. Carefully remove the pneumatic lines from the valve ports. Label each line to ensure correct reconnection.

Remove the mounting bolts securing the old valve bracket to the chassis. Remove the complete old assembly.

Position the new double solenoid valve assembly with bracket in the original mounting location. Secure the bracket using original bolts and torque to FAW Jiefang factory specifications.

Reconnect the pneumatic lines to the correct ports as labeled. Ensure all connections are tight and properly seated to prevent air leaks.

Reconnect the electrical connector. Reconnect the vehicle battery.

Start the engine and allow the air system to reach operating pressure. Check all pneumatic connections for leaks using soapy water or leak detection spray.

Test the function of the solenoid valve by operating the corresponding vehicle controls (brake pedal, clutch, etc.) and listening for proper valve actuation.
