2006 Buick Rendezvous Radiator Parts Questions & Experts Answers

• Q: How to replace the radiator in an A/C system on 2006 Buick Rendezvous?

  A: The a/c Radiator replacement process begins with recovering refrigerant from the a/c system followed by draining the cooling system fluid. The cooling fans must be detached from the cooling Fan Shroud. The hose clamp pliers (J38185) should be used to move the hose clamp at the water pump housing before disconnecting the Radiator outlet hose from the water pump housing. With hose clamp pliers (J38185) in hand raise the vehicle to reduce it and reposition the hose clamp at the Radiator. Then disconnect both the Radiator outlet from the Radiator and remove it. The lower toc line needs detachment from the Radiator before you can lower the vehicle. Untighten and remove the condenser block a/c discharge hose nut with hose clamp pliers (J38185). After disconnecting the hose discard its sealing washer. Immediately spread bargaining materials over both the A/C Hose opening and its discharge end to stop contamination. Apply the same protection to the a/c discharge hose. Securely remove the bolt that attaches the evaporator inlet tube to condenser block then disconnect the tube before sealing the opening with a cap or tape. The Radiator and condenser assembly needs removal before proceeding with the condenser tube clip bolt and condenser mounting bolts to detach the condenser from the Radiator. During installation the condenser requires placement against the Radiator while using mounting bolts tightened to 6 nm (53 inch lbs.) and a condenser tube clip bolt tightened to 2.5 nm (22 inch lbs.). Before attaching the evaporator inlet tube to the condenser block fasten it with a bolt which requires 16 nm (12 ft. Lbs.) torque tightening. Additionally the installation process needs a new sealing washer and removal of the cap or tape from the inlet tube. Use new sealing washer when connecting the a/c discharge hose to the condenser block by tightening the nut to 16 nm (12 ft. Lbs.). The driver should lift the vehicle while the technician connects the bottom tc line to the Radiator then adds the Radiator outlet hose to the Radiator. Use hose clamp pliers (J38185) to reinstall the hose clamp at the Radiator before you lower the vehicle to connect the Radiator outlet hose with the water pump housing and secure it with a hose clamp from the pliers (J38185). The installation process ends by fitting cooling fans into their cooling Fan Shroud after filling the cooling system then a/c system evacuation and recharge before conducting a halogen leak detector (J39400-A) check on all fittings. Checking the transmission fluid level concludes the service procedures.
