REPLACEMENT
PROCEDURE
1. RECOVER REFRIGERANT FROM REFRIGERATION SYSTEM
(a) Start up the engine.
(b) Turn the A/C switch to ON.
(c) Operate the cooler compressor with 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) Recover the refrigerant from the A/C system using a refrigerant recovery unit.
2. CHARGE AIR CONDITIONING SYSTEM WITH REFRIGERANT
(a) Perform vacuum purging using a vacuum pump.
(b) Charge refrigerant HFC-134a (R134a).
Standard:
570 to 630 g (20.10 to 22.22 oz.)
SST: 09985-20010

NOTICE:
Do not start the engine before charging it with refrigerant as the cooler compressor does not work properly without any refrigerant. This could cause the compressor to overheat.
3. WARM UP ENGINE
NOTICE:
Warm up the engine at less than 2,000 rpm for 2 minutes or more after charging it with refrigerant.
4. INSPECT FOR REFRIGERANT LEAK
(a) After recharging the refrigerant gas, check for refrigerant gas leakage using a halogen leak detector.
(b) Perform the operation under these conditions:
When compressor is off: approximately 392 to 588 kPa (4 to 6 kgf/cm2, 57 to 85 psi)
(c) Using a gas leak detector, check the refrigerant line for leakage. |
|
(d) Bring the gas leak detector close to the drain hose with the detector power off. HINT:
HINT: If such reaction is unavoidable, the vehicle must be lifted up. |
|
(e) If a gas leak is not detected from the drain hose, remove the blower motor control from the cooling unit. Insert the gas leak detector sensor into the unit and perform the test.
(f) Disconnect the pressure switch connector and leave it for approximately 20 minutes. Bring the gas leak detector close to the pressure switch and perform the test.
