REPLACEMENT
PROCEDURE
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:
450 to 550 g (15.9 to 19.4 oz.)

NOTICE:
Do not turn the A/C switch on before charging with refrigerant. Doing so will cause the compressor to work without refrigerant, resulting in overheating of the 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.
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.
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:
When the compressor is off: approx. 392 to 588 kPa (4.0 to 6.0 kgf/cm2, 57 to 85 psi)
(c) Using a halogen leak detector, inspect for refrigerant leaks from the refrigerant lines. Text in Illustration

(d) Bring the halogen leak detector close to the drain hose with the detector's power off, and then turn the detector on. Text in Illustration

(e) If a refrigerant leak is not detected from the drain hose, remove the blower motor control from the cooling unit. Insert the halogen 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 halogen leak detector close to the pressure switch and perform the test.
