Air suspension cylinder electromagnetic valve block (Discovery 3)

Removal

1.

CAUTION: Never work on a vehicle supported only by a jack. Always support the vehicle with special stands.

Raise and support the vehicle.

2. Use T4 to release pressure from the air suspension.

For more information, refer to Releasing and Raising Air Suspension System Pressure (60.50.38)

3. Remove the lower air suspension compressor cover.

• Remove 3 bolts.
• Release 5 clamps.

4. Move the air compressor electrical connector aside. Release the 2 clamps.



5.

CAUTION: Before disconnecting or disassembling parts, make sure the area around the contact surfaces is clean and dry. To avoid contamination of the system, plug all open connections.

CAUTION: Visually inspect the ends of the air line for damage or wear. Repair or replace the air line if necessary.

NOTE: Remember the position of the air lines.

Remove the air suspension air spring solenoid valve assembly.

• Disconnect 4 air lines.
• Disconnect the two electrical connectors.
• Release the three rubber valve block mounts.

6. Remove Voss type fittings. Remove and discard cone bushings and couplings.

Installation

1.

CAUTION: Make sure the new Voss type fitting is installed and tightened completely with the corrector plug installed on it.

NOTE: New air suspension components are supplied with Voss style nipples installed and already torqued to the correct value. If a new component is installed, it is not necessary to install new Voss style nipples.

Install new Voss type fittings to the air suspension air spring solenoid valve block. Tighten the connection. (tightening torque 2.5 Nm).

2.

NOTE: Be careful not to let the valve block come loose when connecting the air lines.

Install the air suspension air bladder solenoid valve block.

• Secure the three rubber valve block cushions.
• Connect the electrical connectors.
• Connect the air lines to the Voss type fittings.
• Pull on each air line to ensure it is securely seated in the Voss style fitting.

3. Connect the air compressor electrical connector.



4. Install the lower cover of the air suspension compressor. Insert the bolts and tighten them. (tightening torque 10 Nm).

5. Use T4 to increase the pressure in the air suspension. For more information, refer to Releasing and Increasing the Pressure in the Air Suspension System (60.50.38)
