How to Replace an A/C Hose on Cadillac DeVille?

Starting the suction hose replacement requires recovering refrigerant from the whole system first. Lift the suction hose out of the accumulator after first unscrewing its retaining nut from the accumulator. Caretakers must first lift their vehicle before they remove its front air deflector for replacement of the suction hose. Use your tools to unscrew and then detach the suction hose nut from its position. Check the sealing washers for damage before any replacement as worn out washers do not need lubrication. Attach the suction hose to the compressor while also installing its retaining nut. Buy the suction hose nut and join it to the compressor before tensioning it to 16 n.m (12 lb ft). Proceed with lowering the vehicle before installing the suction hose to the accumulator then fasten the suction hose nut with 20 n.m torque settings (15 lb ft). The a/c system needs to be recharged before conducting halogen leak detector (J 39400-A) procedure on fittings to check for leaks. The conclusion involves reinstalling the front air deflector.
