Level Control Solenoid Valve: Service and Repair

Air Spring Solenoid Valve











Removal and Installation

CAUTION: Suspension fasteners are critical parts because they effect performance of vital components and systems and their failure may result in major service expense. A new part with the same part number or an equivalent part must be installed, if installation is necessary. Do not use a part of lesser quality or substitute design. Torque values must be used as specified during reassembly to make sure of correct retention of these parts.

1. If the air spring solenoid valve is functional, use the scan tool to vent the appropriate air spring(s).
2. With the vehicle in NEUTRAL, position it on a hoist.
3. Disconnect the electrical connector and the air tube in the following sequence.
1. Disconnect the electrical connector.
2. Compress the quick connect lock ring and pull out on the air tube.

4. CAUTION: Remove any dirt or other foreign material from the air spring assembly prior to removing the air spring solenoid valve from the air spring assembly or damage to the air spring solenoid may occur.

Remove the air spring solenoid retainer.

5. WARNING: Vent all air pressure from the air suspension system prior to disconnecting or removing any air suspension components. It is dangerous to remove air suspension components while under pressure. Failure to follow this instruction may result in serious personal injury.

Rotate the air spring solenoid and remove the solenoid.





6. NOTE: Inspect the O-ring for damage and install a new O-ring as necessary. Lubricate the solenoid seal area with silicone grease.

NOTE: When installing the air tubes, make sure the white tube is fully inserted into the fitting for correct installation.

To install, reverse the removal procedure.
