Refrigerant: Service and Repair

REPLACEMENT

1. DISCHARGE 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 1,000 rpm for 5 to 6 minutes to circulate the refrigerant and collect the

compressor oil remaining in each component into the cooler compressor.

d. Stop the engine.
e. Using SST, discharge the refrigerant gas.

SST 07110-58060 (07117-58060, 07117-58070,
07117-58080, 07117-58090, 07117-78050, 07117-88060, 07117-88070, 07117-88080)

2. CHARGE REFRIGERANT

a. Perform vacuum purging using a vacuum pump.

b. Charge refrigerant HFC-134a (R134a).

Standard: 430 ± 30 g (15.17 ± 1.06 oz.)

SST 07110-58060 (07117-58060, 07117-58070,
07117-58080, 07117-58090, 07117-78050, 07117-88060, 07117-88070, 07117-88080)

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 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.

3. WARM UP ENGINE

a. Warm up the engine at less than 1,850 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.

4. CHECK FOR LEAKAGE OF REFRIGERANT

a. After recharging the refrigerant gas, check for refrigerant gas leakage using a halogen leak detector.
b. Perform the operation under the  conditions:

-

Stop the engine.

-

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