  Q: How to replace the radiator in an A/C system on Chevrolet Venture?

  A:

  The first step to replace a Radiator includes recovering refrigerant from the a/c system and draining the cooling system fluids. The installation of the new Radiator begins by uninstalling the cooling fans together with their shroud. Release the clamp tension on the hose using hose clamp pliers (J 38185) until the locking mechanism activates as a method to remove the hose. The hose clamp pliers (J 38185) can be used to loosen the hose clamp near the water pump housing before disconnecting the Radiator outlet hose from that housing. Cut the lower toc line from the Radiator and then unscrew the a/c discharge hose nut from the condenser block before disconnecting it. Directly close the exposed A/C Hose with a cap before contamination occurs and apply tape to the exposed position of the a/c discharge hose too. Release the bolt which maintains the evaporator inlet tube connection to the condenser block and disconnect the tube while using caps or tape for sealing each opening. Start by removing the Radiator and condenser assembly and use the hose clamp pliers (J 38185) to remove tension from the hose clamp at the Radiator as a necessary step to remove the lower Radiator Hose. The condenser must be taken off the Radiator by removing two components: condenser tube clip bolt and Radiator mounting bolts. The installation starts by attaching the condenser to the Radiator while tightening the mounting bolts to 6 nm (53 inch lbs.). The installation proceeds with the lower Radiator Hose after securing the condenser tube clip bolt at 2.5 nm (22 inch lbs). Use a small flat bladed screwdriver to open the hose clamp lock but position the hose on the Radiator before closing it. Connect both pieces of the condenser assembly to the Radiator while removing the moisture barrier from the evaporator inlet tube to apply a new washer before joining the inlet and condenser block together with a 16 nm (12 ft. Lbs.) torque setting. After installing a new sealing washer to the a/c discharge hose you should connect it to the condenser block where you must tighten the nut to 16 nm (12 ft. Lbs.). Finish toc line attachment to Radiator after you hook up the water pump housing to the Radiator outlet hose while loosening the clamp locking mechanism. The procedure requires installing cooling fans with their corresponding shroud followed by filling up the cooling system before evacuating and recharging the a/c system before conducting a leak test on fittings with j 39400-a halogen leak detector. The final step involves checking the transmission fluid measurement.
