*Removal Guideline

Caution: Damage to the vehicle and air suspension system can be incurred if work is carried out in a manner other than specified in the instructions or in a different sequence.

1.To avoid the possibility of short circuits while working with electric components consult your owner's manual on how to disconnect your battery.

2.Consult your vehicle owner's manual, service manual, or car dealer for the correct jacking points on your vehicle and for additional care, safety and maintenance instructions. Under no circumstances should any work be completed underneath the vehicle if it is not adequately supported, as serious injuries and death can occur.

1.Raise the vehicle to locate the air suspension compressor assembly under the rear left side of the vehicle.(picture 1)

2.Remove the four(4)bolts holding the compressor cover to the vehicle.(picture 2,3,4,5)

3.Remove the cover to access the compressor assembly.(picture 6)

4.Remove the air line from the compressor assembly.(picture 7,8)

5.Locate and disconnect the two(2)electrical connectors from the compressor assembly.(picture 9,10)

6.Locate and disconnect the intake hose from the compressor assembly.(picture 11,12)

7.Remove the three(3)mounting nuts and hardware holding the compressor assembly to the vehicle.(picture 13,14,15,16)

8.Remove the compressor assembly from the vehicle.(picture 17,18)

*Air Suspension Compressor Removal

1.Place the compressor assembly on a work bench or other adequate work surface.

2.Remove the three(3)bolts holding the compressor to the mounting bracket.(picture 19)

3.Unclip and remove the wiring harness from the compressor bracket.(picture 20,21)

4.Remove the compressor from the mounting bracket.(picture 22)

*Air Suspension Compressor Installation

1.Install the new compressor into the mounting bracket in the reverse order of removal.

*Warning & Notice

1.When the air compressor being replaced, the matching relay must be replaced according to the corresponding vehicle. If there is something wrong with the relay which leads the compressor to continuous operation without any break, it will burn out the electric motor or other plastic part.

2.When the air compressor being installed, the critical parts such as rubber shock pad and damping spring must be fully fixed on the stand without short installation or missing installation (The air compressor is unequipped with parts). With the anti-vibration parts of short installation or missing installation, a loud noisy instance will happen when the air compressor is working for the sake of resonance.

3.Distribution valve, shock absorber, air tank and tube connector must be checked after air compressor installed to ensure air-tightness. The lifespan of the air compressor will be shortened if the leakage exists.

4.Increased noises while the compressor is running may be caused by a non-functioning compressor mounting. Change the rubbers and springs of the mounting in any case.

5.A porous intake hose often is the cause for a breakdown of the compressor. Change the intake hose and preferably also the filter and noise absorber, because we do not want the compressor to breakdown because of these.

6.Change the relays before installing the compressor even if it seems to still work. This is also a specification by the car manufacturer. Be sure to change the right relays. Relays look similar, that is why there is a risk to change the wrong relays.

7.Be sure to check whether the system is leakproof after repairing. The easiest way to do this is to park the vehicle. Wait for the system to automatically re-adjust if your car has this feature. Then measure the heights from the ground to the lower edge of the fender as exactly as possible and take notes. On the day after measure these heights again and compare them with the ones before. Even a small difference will lead to a damaged compressor and damaged valves in the long run.
