Air Springs-2500
All pressurized air suspension components contain high pressure air (up to 220 psig). Use extreme caution when inspecting for leaks. Wear safety goggles and adequate protective clothing when inspecting or servicing the air suspension system. A sudden release of air under this amount of pressure can cause possible serious or fatal injury.
Support the vehicle by supplemental means before performing any work on the air suspension system to prevent the vehicle from changing height. Before any given component is to be serviced it must be deflated. Servicing the air suspension system without supplemental support, or with pressure in the specific component, can cause possible serious or fatal injury.
When removing an air line from a component and the air line is to be reused, do not remove the 90° fitting or the brass fitting from the air line. If either is removed, the air line must be replaced. New components have air line fittings attached; however if the original air line is used the original fitting must also be used. Do not remove protective caps or plugs from air lines or components until ready to install the air line to prevent moisture or dirt intrusion. All air line fittings must be hand started to avoid cross threading.
New air springs replacements will be at normal ride height.
- Connect the air line (1). Tighten the air line nut to the proper specification. Refer to SPECIFICATIONS .
- Position the air spring on the lower spring seat.
- Install the lower air spring nuts (1). Tighten the lower air spring nut to the proper specification. Refer to SPECIFICATIONS .
- An assistant will be needed for the following steps to assist proper positioning of the air spring, use Short Time Inflate option from the menu selections and the spring will inflate, then verify the air spring is properly seated into the upper mounting points (1).
- Connect the air line (1).
- With a scan tool, using the routines under the Air Suspension Control Module (ASCM), carry out the following:
- Run the Fill Spring From Reservoir routine on the spring that was installed.
- Lower the vehicle to the ground, after 10 seconds, the vehicle will adjust to normal ride height. With the scan tool, using the routines under the Air Suspension Control Module (ASCM), Clear any codes.
- Perform the ASCM Verification Test. Refer to STANDARD PROCEDURE - ASCM VERIFICATION TEST .
- Using a soap and water solution, check the for leaks at the fitting. Correct as necessary.
