• Q: How to Replace an A/C Hose in a Compressor Hose Assembly on 2004 Buick LeSabre?

  A: Refrigerant recovery starts the process followed by disconnecting the negative Battery Cable for replacing the compressor hose assembly. The procedure starts by sliding off the a/c pressure switch electrical connector followed by unfastening and disconnecting the A/C Compressor hose assembly from the compressor at its compressor end. The A/C Compressor hose assembly needs to be disconnected from the condenser after the removal of the hose nut at the condenser end. The next step involves removing the A/C Compressor hose nut connected to the accumulator before disconnecting the hose from the accumulator and proceeding to remove the hose from the vehicle and disconnect the a/c refrigerant pressure sensor from its hose. The procedure for installation starts by attaching the a/c refrigerant pressure sensor to the hose before adding the A/C Compressor hose to the vehicle and connecting it to the A/C Compressor. Seal washers require pre-installation examination for damage as necessary replacements must be conducted before returning the a/c lines and hoses to their original position. The installation procedure for flat washer type seals requires no lubrication substance. Security experts should install the A/C Compressor hose nut while applying 39 n.m (31 lb ft) torque to it. Apply the electrical connector to the a/c pressure switch then route the A/C Compressor hose to the condenser before installing the A/C Compressor hose nut at 20 n.m (15 lb ft). Screw the accumulator hose to its port by tightening the nut to 20 n.m (15 lb ft). Complete the connection of the negative Battery Cable before you recharge the a/c system and evaluate the component fittings with the halogen leak detector (J 39400-A).
