    NOTICE:
    1. Do not operate the cooler compressor before charging refrigerant as the cooler compressor will not work properly without any refrigerant, and will overheat.
    2. Approximately 100 g (3.53 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.


4. WARM UP ENGINE

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

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


5. CHECK FOR REFRIGERANT GAS LEAK

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

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


6. INSTALL RADIATOR GRILLE

  1. Install the radiator grille (LandCruiser RM0000038K501BX_01_0001.html).



7. INSTALL UPPER RADIATOR SUPPORT SEAL

  1. Install the upper radiator support seal with the 13 clips.
