How to install the A/C Accumulator in systems with an auxiliary system on Chevrolet Express 2500?

Question

Accepted Answer

Only vehicles with auxiliary systems need a/c accumulators so start the installation process by recovering a/c refrigerant from the system. The technician should mark a condenser tube section 20 mm (0.75 in) from the bend and then remove it from the condenser. Create another mark 42 mm (1.65 in) beyond the preceding point. Avoid the entry of metal burrs into the condenser tube while performing cutting or removal tasks. Cautiously cut through the marked portion of the condenser tube with the tubing cutter before removing all burrs. The next step involves removing the nuts and ferrules together with the o-rings from the A/C Accumulator but avoid installing the o-rings at this point. Install nuts together with ferrules over each segment of condenser tubing by placing ferrule ends at the narrow portion of the nut. Fit the A/C Accumulator with its flow arrow pointing to the evaporator onto the condenser tube. Maintain a hold on the condenser tube within the A/C Accumulator while torquing the nuts to a specification of 34 n.m (25 lb ft). The next step involves taking out the nuts from the A/C Accumulator but placing o-rings onto the condenser tube. Fasten the two nuts which secure the A/C Accumulator and tighten them with 34 n.m (25 lb ft) of torque. Close the condenser tube before evacuating and recharging the a/c system with the halogen leak detector (J 39400-A) for fitting leak detection.
