CONNECT CABLE TO NEGATIVE BATTERY TERMINAL
Note
When disconnecting the cable, some systems need to be initialized after the cable is reconnected Click here.
INSTALL COWL TOP VENTILATOR LOUVER
for LHD:
Install the 6 clips and cowl top ventilator louver RH.
Note
If the cowl top ventilator louver RH is not properly installed, water may leak into the engine room and cause malfunctions. Therefore, make sure the cowl top ventilator louver RH is installed properly.
for RHD:
Install the 6 clips and cowl top ventilator louver LH.
Note
If the cowl top ventilator louver LH is not properly installed, water may leak into the engine room and cause malfunctions. Therefore, make sure the cowl top ventilator louver LH is installed properly.

ADD COMPRESSOR OIL
When performing work on air conditioning parts, follow the oil guidelines below in order to protect the cooler compressor.
| Part and Condition | Oil Level (cc) | Work Procedure | |
|---|---|---|---|
| Compressor replacement | -100 to -120 | Drain oil from new compressor | |
| Condenser replacement | 35 to 55 | Fill oil into replacement part | |
| Evaporator replacement | 40 to 60 | ||
| A/C pipe replacement | High pressure | 5 to 25 | |
| Low pressure | |||
| When discharging refrigerant gas quickly | 30 to 50 | While applying vacuum, use manifold gauge to fill oil from low pressure side valve | |
CHARGE REFRIGERANT
Perform vacuum purging using a vacuum pump.
Charge refrigerant HFC-134a (R134a).
| Standard | |||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
|
| *a | Amount to be charged | *b | Charge 100 g (3.53 oz) |
| *c | Mean value in proper range | *d | Point where bubbles disappear |
| *e | Overcharged | *f | Pressure |
| *g | Sub-cool system | *h | Refrigerant amount |
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.
WARM UP ENGINE
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.
INSPECT FOR ENGINE COOLANT LEAK
CAUTION:
Do not remove the radiator reservoir cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.
Note
Before each inspection, turn the A/C switch OFF.
Fill the radiator with coolant and attach a radiator cap tester.
Warm up the engine.
Using the radiator cap tester, increase the pressure inside the radiator to 118 kPa (1.2 kgf/cm2, 17 psi), and check that the pressure does not drop.
If the pressure drops, check the hoses, radiator and water pump for leaks. If no external leaks are found, check the heater core, cylinder block and head.
CHECK FOR LEAKAGE OF REFRIGERANT
After recharging the refrigerant gas, check for refrigerant gas leakage using a halogen leak detector.
Perform the operation under these conditions:
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 compressor is off:
approximately 392 to 588 kPa (4 to 6 kgf/cm2, 57 to 85 psi)
| *1 | Halogen Leak Detector |
| *a | Check for Leakage |
Using a halogen 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 halogen leak detector sensor into the unit and perform the test.
Disconnect the connector and wait for approximately 20 minutes. Bring the halogen leak detector close to the pressure switch and perform the test.
