Air Line Fluid Purge

WARNING: Do not remove an air spring under any circumstances when there is pressure in the air spring. Do not remove any components supporting an air spring without either exhausting the air or providing support for the air spring to prevent vehicle damage or personal injury.

WARNING: Disconnecting an air line that is connected to the air compressor can cause personal injury or damage to components as high pressure air is vented uncontrolled.

1. NOTE: Carry out this procedure if fluid (water and or oil) is found in the air line. Purge fluid from rear air lines and install new components if affected.

Disconnect the air line at the air compressor drier.
2. Disconnect the air line from the air springs.
3. Connect a shop air line to the disconnected air line and blow any fluid out.

4. NOTE: When installing the air lines, make sure the white air line is fully inserted into the fitting for correct installation.

Reconnect the air lines at the air springs.
5. Install a new air compressor drier.
6. Reconnect the air line to the air compressor drier.
7. Make sure that all air line fittings are sealed.
