2009 Chevrolet Aveo Parts Questions & Experts Answers

• Q: How to replace the A/C Hose in North America on 2009 Chevrolet Aveo?

  A: The north american procedure for refrigerant tube replacement starts by disconnecting the negative Battery Cable while recovering refrigerant. First remove the bolts from the air cleaner housing followed by the connection from air filter housing assembly and electrical connector from pressure transducer. The technician first disconnects the firewall retaining nut of the evaporator pipe connector block and then removes the pipe connector block to condenser retaining bolt followed by the refrigerant suction hose to liquid pipe block retaining nut . First detach the liquid evaporator pipe support clamp bolt before removing both the liquid evaporator pipe and the refrigerant suction hose. The next step requires removal of the compressor connector block retaining nut on the refrigerant suction hose while also taking out the connector block bolt from the condenser connected to the refrigerant discharge hose and finally removing the discharge hose support clamp bolt. Connect an appropriate cap on the receiver-dryer opening to stop contamination entry. Next install the refrigerant suction hose section inside the vehicle while using new o-rings to seal the condenser connector block and the plate connector block of the liquid condenser. Install the refrigerant discharge hose support clamp bolt first and torque it to 8 nm (71 lb in). Then install and tighten the connector block bolt of the refrigerant discharge hose at the condenser to 16 nm (12 lb ft). Move onto attaching the refrigerant suction hose to the compressor connector block retaining nut at 33 nm (24 lb ft) torque followed by the redundant tightening of the refrigerant suction hose connector block retaining nut to 15 nm (11 lb ft). The liquid pipe connector block must be installed to the condenser retaining bolt before tightening it to 14 nm (10 lb ft). Subsequently, install and tighten the liquid evaporator pipe connector block retaining nut at the firewall to 15 nm (11 lb ft). Mount the air cleaner housing assembly while tightening bolts to 12 nm (106 lb in). Then connect the negative Battery Cable before finishing with an evacuation and recharge of the a/c system.
