Toyota 88471-34010 Tank, Receiver Air Conditioner

Some models have a traditional A/C accumulator, which is mounted at the right front of the engine compartment. Models that do not have a separate A/C accumulator have one that is built into the side of the condenser. First, have the refrigerant discharged by an air conditioning technician. Then, disconnect the negative battery cable. If the A/C accumulator is integral with the condenser, use an Allen wrench to detach the end plug and remove the accumulator from the condenser with a pair of needle-nose pliers. Use new O-rings when installing the new accumulator and tighten the end plug. Be sure to lubricate the O-rings with R-134a compatible refrigerant oil. Installation is the reverse of removal. If the A/C accumulator is separate, disconnect the refrigerant lines from the A/C accumulator and cap the open fittings to prevent the entry of moisture. Unscrew the two mounting bolts and remove the A/C accumulator. Loosen the clamp bolt and slide the A/C accumulator out of the bracket. Install the new A/C accumulator by reversing the removal procedure. If a new A/C accumulator is being installed, add 20cc (0.71 ounce) of R-134a compatible refrigerant oil to it before connecting the lines. Be sure to install new O-rings on the refrigerant lines, and lubricate them with R-134a compatible refrigerant oil, before connecting the lines. Finally, have the system evacuated, charged, and leak tested by the shop that discharged it.

To remove the A/C accumulator, the refrigerant must first be discharged and the negative battery cable disconnected. The refrigerant lines should then be disconnected and the open fittings capped to prevent moisture from entering. The clamp bolt can be loosened and the A/C accumulator slipped out of the bracket. To install, simply reverse the removal process. However, it is important to have the system evacuated, charged, and leak tested. If the A/C accumulator was replaced, 20 ccs of refrigeration oil should be added to the A/C Compressor, using only oil compatible with R-134a refrigerant.

Have the refrigerant discharged and recovered by an air conditioning technician. Remove the grille. Disconnect the refrigerant lines from the A/C accumulator and cap the open fittings to prevent entry of moisture. After the system has been discharged, detach the refrigerant lines from the top of the A/C accumulator and cap them. To access the back-up nuts on the A/C accumulator, remove the coolant reservoir and locate the bracket with the mounting nuts. Loosen the pinch bolt or bracket mounting bolts, whichever is easier to get a wrench on, and remove the A/C accumulator. Installation is the reverse of removal. Have the system evacuated, charged and leak tested by the shop that discharged it. If the A/C accumulator was replaced, have them add about 0.34 ounces of refrigerant oil to the system. Use only the refrigerant oil compatible with the refrigerant of your system (R-134a).

To remove the refrigerant, it is recommended to have it discharged at a dealer service department or an automotive air conditioning repair facility. For 1989 and later models, the radiator grille needs to be removed. The refrigerant lines should be detached from the receiver/drier, and the electrical connector to the pressure switch should be disconnected if equipped. It is important to immediately cap the open fittings to prevent dirt and moisture from entering. The A/C Accumulator can then be unbolted at the clamp and lifted from the vehicle. To install, new O-rings should be placed on the lines and lubricated with clean refrigerant oil. The installation process is the reverse of removal, but it is crucial not to remove the sealing caps until ready to reconnect the lines and to correctly identify the inlet and outlet connections. If a new receiver/drier is installed, 0.7 fluid ounces (20 cc) of refrigerant oil should be added to the system. It is important to note that when replacing entire components, additional refrigerant oil should be added equal to the amount removed with the component being replaced. It is recommended to have the system evacuated, charged, and leak tested by the shop that discharged it.
