- SST
- 09985-20010(09985-02130,09985-02150,09985-02090,09985-02110,09985-02010,09985-02050,09985-02060,09985-02070)
Perform vacuum purging using a vacuum pump.
Charge refrigerant HFC-134a (R134a).
- Standard:
- 750 +-30 g (26.45 +-1.05 oz.)
- NOTICE:
- Do not operate the cooler compressor before charging refrigerant as the cooler compressor will not work properly without any refrigerant, and will overheat.
- Approximately 100 g (3.53 oz.) of refrigerant may need to be charged after bubbles disappear. The refrigerant amount should be checked by quantity, and not with the sight glass.
| 22. WARM UP ENGINE |
Warm up the engine at less than 1,850 rpm for 2 minutes or more after charging refrigerant.
- NOTICE:
- 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.
| 23. CHECK FOR ENGINE COOLANT LEAKS |

1GR-FE:
Check for engine coolant leaks (Toyota Fortuner RM000001TL4000X_02_0004.html).
1KD-FTV:
Check for engine coolant leaks (Toyota Fortuner RM000001X4H000X_01_0004.html).
| 24. CHECK FOR LEAKAGE OF REFRIGERANT |
After recharging the refrigerant gas, check for refrigerant gas leakage using a halogen leak detector.
After recharging the refrigerant gas, prepare the vehicle for a refrigerant gas leakage check by making sure the following conditions are met.
The ignition switch is OFF.
The vehicle is in a place with good air ventilation and without any volatile gases, such as evaporated gasoline or exhaust gas. The detector is very sensitive gases, If volatile gases are unavoidable, the vehicle must be lifted up.
Some refrigerant is remaining in the refrigerant system.
The compressor is OFF and its pressure is approximately 392 to 588 kPa (4 to 6 kgf/cm2).
Using a gas leak detector, check the refrigerant line for leakage.
 |
If a gas leak is not detected on the drain hose, remove the blower motor control (blower resistor) from the cooling unit. Insert the gas leak detector sensor into the unit and perform the test.
Disconnect the connector and leave the pressure switch on for approximately 20 minutes. Bring the gas leak detector close to the pressure switch and perform the test.
