To replace the accumulator, you should recover the refrigerant first. You need to remove the evaporator tube nut and the steam evaporators. Then remove the nut from the evaporator tube and disconnect the electrical connector from the a/c low pressure switch. Unscrew the compressor hose nut off the accumulator and then compressor hose. Then remove the nut (from the evaporator fitting) and the accumulative bracket nut (from retaining stud) before getting rid of the accumulator. Remove o-ring seals, bolt and retaining bracket from the accumulator. For the installation, you should install new o-ring seals, and if you replace the accumulator, add refrigerant oil to the condenser. Mount the retaining bracket onto the accumulator, fasten it with the retaining bracket bolt and tighten it with the torque of 10 n.m (89 lb in). Wrench the accumulator and accelerator bracket nut with a torque of 9 n.m (80 lb in). Next, install the nut to the evaporator fitting, tighten it 16 nm (12 lb ft), the compressor hose to the accumulator and again the compressor hose nut, tighten that to 16 n.m (12 lb ft). Reconnect the electric connector to the a/c low pressure switch and fasten the nut of the evaporator tube to 25 n.m (18 lb ft). Lastly, install the evaporator tube to the evaporator and the evaporator tube nut and tighten to 16n.m (12 lb ft). Evacuate and recharge the system, and conduct a leak test on the fittings with the halogen leak detector (J 39400-A).

In the replacement of the accumulator, first retrieve the loss of refrigerant. It is necessary to separate the evaporator tube nut first as well as the evaporator. Secondly, remove the nut on the evaporator tube and disconnect the a/c low pressure switch's electrical connector. Loosen the compressor hose nut from the accumulator and the compressor hose afterwards. Then, unscrew the nut from the evaporator fitting, and the accumulator bracket nut from the retaining stud prior to unhooking the accumulator. Unload the accumulator from the retaining bracket bolt and the retaining bracket and dispose of the o-ring seals. For the installation, the o-ring seals should be first installed and then the retaining bracket should be fixed to the accumulator. Install tightening bolt of retaining bracket to 10 n.m ( 89lb in) then, install the accumulator and the accumulator bracket nut and tighten the nut to 9 n.m (80 lb in). Install the nut to the evaporator fitting and tighten the nut to 16 n.m (12 lb ft). Connect the compressor hose to the accumulator and tighten it using the compressor hose nut turned to 16 n.m (12 lb ft). Reconnect the electrical connector to the a/c low pressure switch, and install the nut to the evaporator tube and tighten it with a 25 n.m (18 lb ft). Replace the evaporator tube by connecting it to the evaporator and fasten it using the evaporator tube nut, which is to be tightened to 16 n.m (12 lb ft). Last, but not least, evacuate and recharge system, do the leak test on the fittings of the component with the halogen leak detector (J 39400-A).

The refrigerant recovery process must start first before performing accumulator replacement. You start by removing the Evaporator tube nut from the Evaporator and its corresponding tube. Follow by removing the Evaporator tube nut before disconnecting the electrical connector from the a/c low pressure switch. Once the compressor hose opens up pressurized air will escape through an appropriate receptacle. Drain the nut from both the Evaporator fitting and the accumulator bracket from its retaining stud before you remove the accumulator. Detach the retaining bracket bolt and retaining bracket from the accumulator then throw away the o-ring seals. Installation requires new o-ring seals and additional refrigerant oil added to the condenser when replacing the accumulator. Secure the retaining bracket bolt against the accumulator through the retaining bracket to a torque of 10 n.m (89 lb in). Position the accumulator and apply the accumulator bracket nut ensuring this connection reaches 9 n.m (80 lb in) of torque. Install the nut to the Evaporator fitting first and tighten it to 16 n.m (12 lb ft). Then attach the compressor hose to the accumulator and fasten the compressor hose nut with another 16 n.m (12 lb ft) torque value. Tighten the Evaporator tube nut to 25 n.m (18 lb ft) after connecting the electrical connector to the a/c low pressure switch. Install the Evaporator tube between the Evaporator followed by the Evaporator tube nut with torque setting at 16 n.m (12 lb ft). System evacuation and recharging must follow a leak test using the halogen leak detector (J 39400-A) for component fittings.

Secondly, remove the nut on the evaporator tube and disconnect the a/c low pressure switch's electrical connector. Loosen the compressor hose nut from the accumulator and the compressor hose afterwards. Then, unscrew the nut from the evaporator fitting, and the accumulator bracket nut from the retaining stud prior to unhooking the accumulator. Unload the accumulator from the retaining bracket bolt and the retaining bracket and dispose of the o-ring seals. For the installation, the o-ring seals should be first installed and then the retaining bracket should be fixed to the accumulator. Install tightening bolt of retaining bracket to 10 n.m ( 89lb in) then, install the accumulator and the accumulator bracket nut and tighten the nut to 9 n.m (80 lb in). Install the nut to the evaporator fitting and tighten the nut to 16 n.m (12 lb ft). Connect the compressor hose to the accumulator and tighten it using the compressor hose nut turned to 16 n.m (12 lb ft). Reconnect the electrical connector to the a/c low pressure switch, and install the nut to the evaporator tube and tighten it with a 25 n.m (18 lb ft). Replace the evaporator tube by connecting it to the evaporator and fasten it using the evaporator tube nut, which is to be tightened to 16 n.m (12 lb ft). Last, but not least, evacuate and recharge system, do the leak test on the fittings of the component with the halogen leak detector (J 39400-A).
