• Q: How to replace the A/C Condenser with RPO Code CZ3 on 2003 Cadillac CTS?

  A: Starting the condenser replacement with rpo code cz3 requires refrigerant recovery as your first step. The j 39400-a detector should be used for leak testing all fittings on repaired or reinstalled components. Start by taking off the radiator support brackets and upper condenser mounting bolts and auxiliary cooling fan. The operator must begin condenser inlet hose replacement by removing the inlet hose bolt at the condenser and must slowly pull the line to safeguard the o-ring. After minimizing discharge hose movement at the condenser unit the operator should remove the condenser. To install the new condenser you should start by adding proper refrigerant oil followed by installing the condenser and finally installing the auxiliary cooling fan. Put refrigerant oil on the o-ring then attach the discharge hose to the condenser where the installation requires the discharge hose bolt to attain a torque amounting to 5.4 n.m (48 lb in). Apply the lubricating process on the o-ring a second time before attaching the condenser inlet hose to the condenser with its inlet hose bolt along with the proper torque setting at 5.4 n.m (48 lb in). Fasten the air deflector and upper condenser bolts while tightening them to 3.9 n.m (35 lb in), then return the radiator support brackets to their original position. Evacuate and recharge the refrigerant system as the last step.
