  Q: How to Replace an A/C Hose in a Compressor Hose Assembly on Chevrolet Classic?

  A:

  The first step to replace the compressor hose assembly is to recover any present refrigerant. The sensor separation starts with disconnecting the electrical component from the pressure monitor located on the hose. Begin by unwinding the bolt which anchors the compressor hose bracket to the Fan Shroud and afterward remove the compressor hose assembly to condenser nut and final step is to separate the compressor hose assembly from the condenser by discarding the seal washer. Rise the car and take off the right front fender liner. Neutralize the compressor hose assembly nut which mounts to the accumulator before separating the assembly from its mounting point on the accumulator while discarding the existing seal washer. Proceed to remove the block fitting bolt from the compressor and disconnect the compressor hose assembly from the compressor unit by discarding both seal washers. Install block fitting bolt to compressor when it is 33 n.m (24 lb ft) tight. To start the installation, place new seal washers onto compressor ports first. Begin installation by attaching new seal washers to the accumulator location of the compressor hose then joining the compressor hose assembly and nut to the accumulator while tightening this nut to 25 n.m (18 lb ft). Place the right front fender liner back and lower the vehicle before installing the new seal washer on the condenser end of the compressor hose. After fitting the condenser hose with its nut connect it tightly to 25 n.m (18 lb-ft). Insert the compressor hose bracket with its bolt onto the Fan Shroud before torquing the bolt to 10 n.m (89 lb in). The last step involves mounting the new hose being connected to the refrigerant pressure sensor after installing its o-ring. Complete a vacuum process of the refrigerant system before charging it with new gas while using the halogen leak detector (J 39400-A) to inspect all component fittings for leaks.
