For 1990-2009 cars

At the rear struts and at the pressure limiter valve, the air tube connectors are held on with spring clips which snap into the grooves of the struts air fittings or pressure limiter valve. Air tube connectors are sealed using two O-rings.

Important: Before disconnecting any air tube, clean the connector and the surrounding area to prevent dirt and other foreign material from entering the ALC system.

To disconnect an air tube from a strut or from the pressure limiter valve, rotate the spring clip 90 degrees out of the slots, and pull the connector off.

Important: Ensure that the air tube is routed correctly and all fasteners are used.

To connect an air tube to a strut or to the pressure limiter valve, use the following instructions:

1. Lubricate the two O-rings using silicone lubricant.
2. Rotate the spring clip 90 degrees into the slots.
3. Push the air tube connector on the strut fitting or pressure limiter valve until the spring clip snaps into the groove.

### Removal Procedure

1. Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.

Important: Steps 2 through 4 apply to the air tube that is routed from the air compressor to the crossover air tube. Step 5 through 8 apply to the crossover air tube (routed between the struts).

2. Disconnect the air tube from the pressure limiter valve.
3. Remove the air tube from the height sensor harness clips.
4. Disconnect the air tube from the crossover air tube tee (1) or the inflator valve air tube (2) (vehicles with optional inflator valve only).
5. Remove both rear wheels. Refer to Wheel Removal in Tires and Wheels.
6. Disconnect the crossover air tube from the right strut and two clips.
7. Disconnect the crossover air tube from the left strut and two clips.
8. Disconnect the air tube (coming from the air compressor) from the crossover air tube tee.
9. Remove the crossover air tube tee from the vehicle.

### Installation Procedure

Important: Steps 1 through 5 and 8 apply to the crossover air tube (routed between the struts). Steps 5 through 8 apply to the air tube that is routed from the air compressor to the crossover air tube.

1. Install the crossover air tube tee on the vehicle.
2. Connect the air tube to the right rear strut and install the air tube in two clips.
3. Connect the air tube to the left rear strut and install the air tube in two clips.
4. Install both rear wheels. Refer to Wheel Installation in Tires and Wheels.
5. Connect the air tube (from the air compressor) to the crossover air tube tee (1) or the inflator valve air tube (2) (vehicles with optional inflator valve only).
6. Install the air tube in the height sensor harness clips.
7. Connect the air tube to the pressure limiter valve.

Important: Before driving the vehicle, turn the ignition on and wait approximately 45 seconds. This will permit the ELC system to execute the ARC, ensuring that the air adjustable struts are filled with residual pressure.

8. Lower the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
