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

  A: The first step in compressor hose assembly replacement requires the recovery of refrigerant from the system. Start by detaching the compressor suction/discharge hose bolt with its washer then disconnect the hose from the compressor before removing the sealing washers. You should remove the compressor suction hose from the accumulator while discarding the o-ring seal before taking off the lower Radiator Hose. The compressor discharge hose attachment from the condenser requires removal while throwing away the o-ring seal. Installation requires installing a new o-ring seal which received a 525 viscosity refrigerant oil coating and attaching the compressor discharge hose to the condenser while tightening it to 28 n.m (21 lb ft). The technician should attach the lower Radiator Hose to which he should apply another new o-ring seal that has received 525 viscosity refrigerant oil coating then connect the compressor suction hose to the accumulator point while tightening the bolts to 48 n.m (35 lb ft). Position the sealing washers after which you can hook the compressor suction and discharge hose to the compressor along with the washer and bolt before tightening the bolt to 33 n.m (24 lb ft). The system needs evacuation and recharging as the final step.
