Refrigerant: Service and Repair
HEATING / AIR CONDITIONING: REFRIGERANT: REPLACEMENT
REPLACEMENT
1. RECOVER REFRIGERANT FROM REFRIGERATION SYSTEM
(a) Start up the engine.
(b) Turn the A/C switch on.
(c) Operate the cooler compressor at an engine speed of approximately 1000 rpm for 5 to 6 minutes to circulate the refrigerant. This causes most
of the compressor oil from the various components of the A/C system to collect in the A/C compressor.
(d) Stop the engine.
(e) Recover the refrigerant from the A/C system using a refrigerant recovery unit.
2. CHARGE WITH REFRIGERANT
(a) Perform vacuum purging using a vacuum pump.
(b) Charge with refrigerant HFC-134a (R134a).
Standard:
410 to 470 g (14.5 to 16.6 oz.)
SST: 09985-20010
09985-02010
09985-02050
09985-02060
09985-02070
09985-02080
09985-02090
09985-02110
09985-02130
09985-02140
09985-02150
NOTE: Do not turn the A/C on before charging with refrigerant. Doing so will cause the cooler compressor to work without refrigerant,
resulting in overheating of the cooler compressor.
HINT: Ensure that sufficient refrigerant is available to recharge the system when using a refrigerant recovery unit. Refrigerant recovery units
are not always able to recover 100% of the refrigerant from an A/C system.
3. WARM UP ENGINE
(a) Keep the A/C switch on for at least 2 minutes to warm up the compressor.
NOTE: Be sure to warm up the compressor when turning the A/C on after removing and installing the cooler refrigerant lines (including the
compressor), to prevent damage to the compressor.
4. INSPECT FOR REFRIGERANT LEAK
(a) After recharging with refrigerant, inspect for refrigerant leaks using a halogen leak detector.
(b) Carry out the test under the following conditions:
-
Turn the ignition switch off.
-
Secure good ventilation (the halogen leak detector may react to volatile gases which are not refrigerant, such as evaporated gasoline and
exhaust gas).
-
Repeat the test 2 or 3 times.
-
Make sure that there is some refrigerant remaining in the refrigeration system.
When the compressor is off: approx. 392 to 588 kPa (3.9 to 5.9 kgf/cm2, 57 to 85 psi)
(c) Using a halogen leak detector, inspect for refrigerant leaks from the refrigerant lines.
