• Q: How to replace the A/C Accumulator on 2007 Chevrolet Colorado?

  A: The first step before replacing the A/C Accumulator involves appropriate methods for collecting the refrigerant. The removal of the grille requires extra caution because disconnecting the hoses or lines should not occur until the system fully empties its r134a fluid to prevent injuries. First detach the condenser hose bolt and its attachment to the A/C Accumulator then remove the evaporator tube bolt while dislodging its tube. The condenser hose and evaporator tube assembly should receive caps which stop both moisture entry and oil spillage. Start by removing both bolts from the A/C Accumulator assembly bracket and then separate the A/C Accumulator unit by unwinding the clamp bolt. When adding a new A/C Accumulator to the system users should carefully determine the required pag oil amount. Install the A/C Accumulator bottle into the clamp without tightening while adding new o-rings that require pag oil for internal circulation and 525 viscosity mineral oil on fittings to avoid compressor breakdown. Fasten the bracket bolts of the A/C Accumulator and tighten the A/C Accumulator clamp bolt to 5 n.m (44 lb in). Disconnect the condenser hose from the condenser cap while plugging it and install a fresh seal washer. The evaporator tube needs installation onto the A/C Accumulator while using an evaporator tube bolt to reach a torque tightness of 20 n.m (15 lb ft). The condenser hose needs connection to the A/C Accumulator before using a hand tool to start securing the condenser hose bolt to 20 n.m (15 lb ft). The evacuation and recharging process of the a/c system requires a j39400-a halogen leak detector to analyze the component fittings before reinstalling the grille.
