• Q: How to Replace an A/C Hose in a Compressor Hose Assembly on 2002 Chevrolet Malibu?

  A: The first step to replace the compressor hose assembly requires the recovery of refrigerant. First remove the refrigerant pressure sensor from the hose after detaching its electrical connector. Start by removing the bolt attaching the compressor hose bracket to the Fan Shroud then proceed with disconnecting the compressor hose assembly to condenser nut followed by removing the compressor hose assembly from the condenser throwing out the seal washer. The right fender liner should be unwrapped from the vehicle when raised. Disassemble the compressor hose assembly to the accumulator by removing its securing nut and detaching it from the accumulator along with disposing of the seal washer. Use tools to remove the block fitting bolt installed in the compressor while you unfasten the compressor hose assembly from the compressor unit then dispose all seal washers. Start by putting new seal washers at the compressor ports before securing the block fitting bolt to the compressor while achieving a torque of 33 n.m (24 lb ft). After installing the new seal washer on the accumulator end of the compressor hose you should attach the compressor assembly which includes the nut; tighten the nut to 25 n.m (18 lb ft). Place the new seal washer at the compressor end of the hose before reattaching the condenser end of the compressor hose assembly. Install the right front fender liner then lower the vehicle. Fasten the compressor hose along with the nut to the condenser while using a torque wrench to set it at 25 n.m (18 lb ft). Reinstall the compressor hose bracket along with its bolt to the Fan Shroud by tightening the bolt to 10 n.m (89 lb in). The new hose must receive the sensor pressure sensor o-ring prior to adding the sensor. The last step involves evacuating and pressurizing the refrigeration system while conducting leak detection of fittings with the halogen leak detector (J 39400-A).
