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

  A:

  The first step for installing the A/C Accumulator in vehicles with an auxiliary system involves recovering the refrigerant from the a/c system. Cut the marked section of the condenser tube at 20 mm (0.75 in) from the bend then measure 42 mm (1.65 in) more forward to create another mark on the tube. Use a tubing cutter to cut the marked section on the condenser tube avoiding any metal burrs entering the tube when performing this operation. Put the burrs off the tube then insert the appropriate sized ferrules and nuts onto their respective sections of the condenser tube. Fix ferrules into the condenser tube with small ends toward the nuts before installing the A/C Accumulator where the flow arrow points toward the Evaporator. You should hold the condenser tube within the A/C Accumulator while tightening the nuts to 34 n.m (25 lb ft). Wrap up the A/C Accumulator nut removal by installing the o-rings to the condenser tube before fixing the nuts back to the accumulator while tightening to 34 n.m (25 lb ft). The final process involves reinstalling the condenser tube to the condenser while following up with a/c system evacuation and charging and conducting a leak test on fittings through usage of the halogen leak detector (J 39400-A).

  Q: How to Service and Repair the A/C Accumulator on Chevrolet Express 2500?

  A:

  To service and repair the accumulator hvac, one should start by recovering the refrigerant from the a/c system. Next, tap off the coolant recovery or surge tank, followed by the a/c lines from the accumulator. Remove the electrical connectors from the low-pressure sensor and then take away the accumulator and the bracket . For installation, first reinstall the accumulator and the bracket onto the vehicle to tighten the screws to the Evaporator cause to 6 n.m (53 lb in) and the nut retaining the accumulator to the a/c Evaporator and blower module stud to 16 n.m (12 lb ft). Rejoin the low pressure sensor electrical connectors and for the accumulator compressor hose assembly, tighten it to 48 n.m (35 lb ft). Last but not the least, reinstall the coolant recovery or surge tank and evacuate and recharge the a/c system and perform a leak test on the fittings of the component using halogen leak detector (J 39400-A).
