• Q: How to Replace an A/C Hose in a Compressor Hose Assembly on 2000 Chevrolet Malibu?

  A: The first step to replace the compressor hose assembly requires the recovery of refrigerant. You must extract both the refrigerant pressure sensor from its hose and the bolt that maintains the compressor hose bracket to the Fan Shroud. You must detach the compressor hose from the condenser by taking out both the nut and hose and getting rid of the o-ring seal. You should begin by elevating the vehicle while taking out the splash shield that covers the right wheelhouse. Release the nut which attaches the compressor hose to the accumulator before removing the hose completely while discarding both seals. First separate the compressor hose assembly around the block fitting bolt then pull out the assembly from the compressor unit while discarding the sealing washers. The new compressor hose assembly should be placed into position while new sealing washers get installed at the compressor ports. Fitting the block assembly to the compressor rear head requires proper bolt tightening to 33 n.m (24 lb ft). Place an accumulator-end o-ring seal on the compressor hose and apply 525 viscosity refrigerant oil onto it before attaching the hose to the accumulator port while tightening the nut to 25 n.m (18 lb ft). Place the right wheelhouse splash shield back and bring down the vehicle. Align the condenser end of the compressor hose with a new o-ring that received 525 viscosity refrigerant oil treatment and fix it as per the instruction with a torque of 25 n.m (18 lb ft). Secure the compressor hose bracket along with its bolt to the Fan Shroud by tightening the bolt to 10 n.m (89 lb in). Complete the procedure by mounting the refrigerant pressure sensor to the new hose and charging the a/c system for testing the operation and conducting a leak test.
