Compressor Assembly

The service and repair of the air suspension compressor must begin with turning off electrical power to the air suspension system to stop unexpected air spring inflation or deflation that would shift the vehicle while you work. The first step involves turning off the air suspension switch and removing both the pushpin-mounting engine air cleaner and air compressor drier cover through pushpin extraction. Proceed to extract the snorkel after removing its pushpin. Disconnection of the air compressor begins with compressing and removing the locking ring followed by extracting the air line then disconnecting the electrical harness. First raise the vehicle then install support before removing the nuts and gently lower it to access the air compressor. The installation of air lines into the compressor drier requires at least 3 mm (1/8 inch) of visible white air line extended beyond the fitting. The process terminates with steps that are opposite to the removal actions.

The first step for servicing the air suspension compressor involves turning off power to the system because unintended air spring movements might shift the vehicle while repairing which could cause injury to personnel. The switch for air suspension service should be set to OFF. The vehicle should rest in NEUTRAL position while positioned on a hoist. The air cleaner along with the air compressor drier cover needs to be removed by detaching the pushpins. Open the compressor canister by removing its pushpin and pull out the canister. To remove the air suspension compressor plug the quick connect locking ring by compressing it before pulling the air line out then disconnect the electrical connector. When reinstalling the air suspension compressor retain the nuts tightly at 7 Nm (62 inch lbs.). The last step is compressor air suspension removal. Check the installation success by inserting at least 3 mm (1/8 inch) of white air line visibility in the compressor drier fitting before finishing the installation procedure.

The air suspension compressor servicing process begins with cutting off electrical power to prevent unexpected air spring operation that might shift the vehicle and lead to injury. The air suspension service switch should point towards OFF before proceeding. The vehicle requires positioning on a hoist while residing in NEUTRAL gear. The service starts by taking out the air cleaner along with the air compressor drier cover which requires removal of pushpins and unlatching the cover. After removing its pushpin the canister can be extracted. Unplug the air suspension compressor by unlocking the quick connect using continuous pressure while easing the air tube from its holder and separating the power cable. When reassembling the compressor bracket secure its three nuts to 5 Nm (44 lb-in) torque. Remove the air suspension compressor assembly as the last step. The installation process requires inserting at least 3 mm (1/8 in) of white tube into the air tubes' fitting for the compressor drier, followed by reversing the removal steps to finish the installation.

The first step before commencing air suspension compressor service starts with turning off electrical power to avoid unexpected air spring changes that create vehicle shifts leading to potentially severe injuries. Activating the air suspension service switch should be set to OFF position. Set the NEUTRAL gear and position the vehicle on a hoist. Start the process by removing the air cleaner and proceeding to take out the drier cover by first detaching pushpins and then removing the cover. The following step involves pulling out the canister through its attached pushpin. Cable the air suspension compressor by depression of the quick connect locking ring to remove the air tube followed by disconnecting the electrical connector. When reinstalling the air suspension compressor bracket nuts use a torque of exactly 5 Nm (44 lb-in). The air suspension compressor assembly needs removal as the final step of this process. For the air tubes into the compressor drier you must insert minimum 3 mm (1/8 in) visible white tube at the fitting point during the reinstall process. Reinstallation should proceed in the reverse order of removal steps.

The first step for servicing and repairing the air suspension compressor requires turning off power to the air suspension system because unexpected air spring changes can lead to vehicle shifts posing significant personal injury risks. It is important to turn the air suspension service switch to OFF state. Place the vehicle in NEUTRAL position before setting it onto the hoist. Start the service or repair by removing the air cleaner followed by dealing with the air compressor drier cover while you take out its pushpins first. You must first discard the canister pushpin to extract the canister itself from the system configuration. Use the quick connect locking ring to press then pull out the air tube leading to the disconnection of the air suspension compressor followed by disconnecting its electrical connector. You should tighten the three air suspension compressor bracket nuts to 44 lb-inch and 5 Nm (44 lb-inch) after reattaching them. To finish the task remove the air suspension compressor assembly. You should insert at least 3 millimeters (1/8 inch) of white tube through the fitting before assembly of air tubes to the compressor drier while following the opposite procedure to installation. Reinstall the components by using new parts with identical part numbers or equivalent parts while following the specified torque requirements to maintain correct component retention.

To protect against sudden air spring changes that could harm people, the first step before compressor servicing is ensuring power to air suspension power is disabled. The air suspension service must be set to OFF position. Position the vehicle into NEUTRAL and maintain it on the hoist. Start the process by removing the air cleaner followed by removal of the air compressor drier cover using a pushpin first and a cover second protocol. Finish the task by pulling out the canister through its pushpin removal. Disconnect the air suspension compressor by using the quick connect locking ring compression to extract the air tube before separating the electric connector. Reassemble the air suspension compressor brackets by tightening their bracket nuts to 5 Nm (44 lb-in) torque setting. The installation ends with removing the air suspension compressor assembly. The installation requires feeding at least 3 mm (1/8 in) of visible white tube into the fittings where air tubes connect to the compressor drier before proceeding with installation.

Ensure that at least 3 mm (1/8 in) of visible white tube is inserted into the fitting.

Remove the air cleaner and the air compressor drier cover by taking out the pushpins, then remove the canister pushpin and the canister itself.

Raise and support the vehicle.

Remove the snorkel pushpin and take out the snorkel.

Compress the quick connect locking ring and pull out the air line, then disconnect the electrical connector.

Ensure that a minimum of 3 mm (1/8 inch) of visible white air line is inserted into the fitting for the compressor drier.
