• Q: How to replace the Air Suspension Compressor on 2007 Cadillac STS?

  A: Start by elevating and stabilizing the vehicle before installing a new Air Suspension Compressor. You need to start by detaching the exhaust system from its rear exhaust hangers before you uninstall the automatic level control (ALC) compressor bracket mounting bolts to lower the alc compressor assembly carefully. Loosen the alc compressor clamp air tube while disconnecting the alc electrical harness connector. Separate the side mounting nut from the alc compressor bracket while removing the compressor assembly including bracket from the vehicle. Start by taking the alc compressor bracket mounting screw and electrical harness connector out from the bracket along with disconnecting the bleed hose from its clip. Remove the screws attached to the alc bracket and later remove the bracket from the alc compressor. Install the alc bracket on the compressor by screwing alc compressor screws and tightening them up to 9 n.m (80 lb in). You must first attach the bleed hose to the clip followed by the electrical connector installation onto the alc compressor bracket and the final connection between the air tube and the alc compressor. Reconnect the alc electrical harness connector while you install the alc bracket side mounting nut and secure the alc bracket mounting bolts which need to be tightened to 9 n.m (80 lb in). The last step involves reattaching the exhaust system to rear exhaust hangers while lowering down the vehicle.
