  Q: How to service and repair the A/C Accumulator on Toyota Tundra?

  A:

  The first step in servicing and repairing the A/C Accumulator involves discharging the refrigerant from the refrigeration system after evacuating air and then charging the system with exact amounts of 600 plus or minus 50 g (21.16 plus or minus 1.76 oz.) for Access Cab and Standard Cab. You must disconnect the liquid tubes from the A/C accumulator by removing its two bolts while torquing them to 5.4 N.m precisely (55 kgf.cm, 48 in.lbf) before you immediately place caps on the open fittings to stop moisture and dirt from entering the system. A technician should use compressor oil to prepare two new O-rings before inserting them onto the tubes. The holder bolt requires removal to access the downward pull of the A/C accumulator yet the oil addition (20 cc) of ND-OIL 8 or equal to the compressor should be performed before new A/C accumulator installation. Remove the bolt and holder before reversing the previous steps to reinstall the components.

  Q: How to install the A/C Accumulator and connect the necessary components on Toyota Tundra?

  A:

  Begin cooler dryer installation by first performing the surface treatment of new O-ring and accessing cap with ND-OIL 8 or equivalent compressor oil. The installation process starts by inserting the O-ring onto the cap. Installet the cap onto the modulator with a torque of 2.9 Nm (30 kgf-cm, 26 in-lbf) through the use of a 14 mm socket hexagon wrench. You should install the cooler condenser assembly with 2 bolts that need to be tightened to 9.8 Nm (100 kgf-cm, 87 in-lbf). For connecting the air conditioning tube and accessory assembly, remove the vinyl tape from the pipe and the cooler condenser, apply ND-OIL 8 or equivalent compressor oil to a new O-ring and the fitting surface of the pipe joint, install the O-ring on the air conditioning tube and accessory, and connect them to the cooler condenser with 2 bolts, also at a torque of 9.8 Nm (100 kgf-cm, 7 ft-lbf), while avoiding contact between tools and the pipe and holding the pipe near the connector during tightening. The discharge hose requires vinyl tape removal followed by application of compressor oil on a fresh O-ring installation and subsequent attachment to the cooler condenser using a bolt torqued to 9.8 Nm (100 kgf-cm, 7 ft-lbf). The process requires no tool contact with the pipe and maintaining the pipe near the connector. The Radiator assembly should be installed per engine type selection which includes 1GR-FE, 2UZ-FE, 3UR-FE and 3UR-FBE. The installation of the front bumper cover starts with the Steel Type or Resin Type procedures. The negative battery terminal reception order should be followed with the cable attachment and additional system initialization may be needed in specific cases. Engage the refrigerant charge process while warming the engine to completion followed by detecting refrigerant gas leaks and testing the SRS warning light through diagnostic trouble codes.
