      Standard
      440 +/-30 g (15.5 +/-1.1 oz)
      A00DTEOE26

      Note


      • Do not operate the cooler compressor before charging refrigerant as the cooler compressor will not work properly without any refrigerant, and will overheat.

      • Approximately 200 g (7.05 oz) of refrigerant may need to be charged after bubbles disappear. The refrigerant amount should be checked by measuring its quantity, and not with the sight glass.

  32. WARM UP ENGINE


    1. Warm up the engine at less than 1850 rpm for 2 minutes or more after charging the refrigerant.

      Note

      Be sure to warm up the compressor when turning the A/C switch on after removing and installing the cooler refrigerant lines (including the compressor) to prevent damage to the compressor.

  34. CHECK FOR REFRIGERANT GAS LEAK


    1. After recharging the refrigerant gas, check for refrigerant gas leakage using a halogen leak detector.

    2. Perform the operation observing the following instructions:


      • Stop the engine.

      • Secure good ventilation (the halogen leak detector may react to volatile gases other than refrigerant, such as evaporated gasoline or exhaust gas).

      • Repeat the test 2 or 3 times.

      • Make sure that some refrigerant remains in the refrigeration system.

        Tech Tips

        When the compressor is off: approximately 392 to 588 kPa (4.0 to 6.0 kgf/cm2, 57 to 85 psi).

      *1 Check for Leakage
      *2 Halogen Leak Detector

      Using a halogen leak detector, check the refrigerant line for leakage.

    4. If a gas leak is not detected from the drain hose, remove the blower motor control (blower resistor) from the cooling unit. Insert the halogen leak detector sensor into the unit and check for gas leakage.

    5. Disconnect the pressure switch connector and wait for approximately 20 minutes. Bring the halogen leak detector close to the pressure switch and check for gas leakage.
