Q: How to replace the A/C Hose on 2009 Cadillac STS?
A: A technician must recover all refrigerant before starting the condenser tube replacement. The front air deflector and condenser tube to condenser retaining bolt need removal when working on 3.6l or 4.6l engine air cleaner assemblies. Start by disconnecting the a/c quick connect fitting at the liquid line before raising and supporting the vehicle. Start by removing the front air deflector before proceeding to disconnect the condenser tube to condenser retaining bolt. The technician disconnects the condenser tube from both the fan shroud retainer clip and the condenser and liquid line before disconnecting the a/c pressure sensor electrical connector to remove the condenser tube. Set aside the a/c pressure sensor after you detach it while removing its o-rings. New o-rings should be placed onto the condenser tube before installing the a/c pressure sensor followed by the condenser tube. After reattaching the a/c pressure sensor electrical connector you should connect the condenser tube to the liquid line followed by connecting the condenser and the fan shroud retainer clip. Tighten the condenser tube to condenser retaining bolt to 9 nm (80 lb in). After lowering the vehicle the front air deflector should be replaced while the a/c quick connect fitting should be installed onto the liquid line. The conclusion of the repair process includes installing the appropriate engine air cleaner assembly followed by evacuating and pressurizing the a/c system before using j 39400-a to check for leakage at component fittings.
