• Temperature setting: Full cold
• Fan speed: Maximum speed set

7.

Run the engine at approximately 1,500 rpm for 2 minutes or more.

8.

Stop the engine. Check again for refrigerant leakage. GO TO 4.

WARNING:

Be careful not to get burned when the engine is hot.
NOTE:
• Start refrigerant leakage check immediately after the engine is

stopped.

• When refrigerant circulation is stopped, pressure on the low-

pressure side rises gradually, and after this, pressure on the
high-pressure side falls gradually.

• The higher the pressure is, the easier it is to find the refriger-

ant leakage.

Recycle Refrigerant

INFOID:0000000006485594

WARNING:

• Always use HFC-134a for A/C refrigerant. If CFC-12 is accidentally charged, compressor is damaged

due to insufficient lubrication.

• Always observe and follow precautions described on refrigerant container. Incorrect handling may

result in an explosion of refrigerant container, frostbite, or the loss of eyesight.

• Never breathe A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose, or

throat.

• Never allow HFC-134a to be exposed to an open flame or others because it generates poisonous gas

when in contact with high temperature objects. Keep workshop well ventilated.

1.

Perform lubricant return operation. Refer to 

HA-23, "Perform Lubricant Return Operation"

. (If refrigerant or

lubricant leakage is detected in a large amount, omit this step, and then GO TO 2.)

CAUTION:

Never perform lubricant return operation if a large amount of refrigerant or lubricant leakage is
detected.

2.

Check gauge pressure readings of recovery/recycling/recharging equipment. When remaining pressure
exists, recycle refrigerant from high-pressure hose and low-pressure hose.
NOTE:
Follow manufacturer instructions for the handling or maintenance of the equipment. Never fill the equip-
ment with non-specified refrigerant.

3.

Remove A/C service valve cap from the vehicle.

4.

Connect recovery/recycling/recharging equipment to A/C service valve.

5.

Operate recovery/recycling/recharging equipment, and recycle refrigerant from the vehicle.

6.

Evacuate air for 10 minutes or more to remove any remaining refrigerant integrated to compressor lubri-
cant, etc.

7.

Refrigerant recycle operation is complete.

Charge Refrigerant

INFOID:0000000006485595

WARNING:

• Always use HFC-134a for A/C refrigerant. If CFC-12 is accidentally charged, compressor is damaged

due to insufficient lubrication.

• Always observe and follow precautions described on refrigerant container. Incorrect handling may

result in an explosion of refrigerant container, frostbite, or the loss of eyesight.

• Never breathe A/C refrigerant and lubricant vapor or mist. Exposure my irritate eyes, nose, or throat.
• Never allow HFC-134a to be exposed to an open flame or others because it generates poisonous gas

when in contact with high temperature objects. Keep workshop well ventilated.

1.

Connect recovery/recycling/recharging equipment to the A/C service valve.

2.

Operate recovery/recycling/recharging equipment, and evacuate air from A/C system for 25 minutes or
more.

CAUTION:

Evacuate air for 15 minutes or more if the parts are replaced.

3.

Check the airtightness of A/C system for 25 minutes or more. If pressure rises more than the specified
level, charge A/C system with approximately 200 g (0.4 lb) refrigerant and check that there is no refriger-
ant leakage. Refer to 

HA-19, "Leak Test"

.

CAUTION:

Check the airtightness for 15 minutes or more if the parts are replaced.

4.

If parts other than compressor are replaced, fill compressor lubricant according to parts that are replaced.

5.

Charge the specified amount of refrigerant to A/C system.

6.

Check that A/C system operates normally.

7.

Disconnect recovery/recycling/recharging equipment. (Collect the refrigerant from the high-pressure hose
and low-pressure hose of recovery/recycling/recharging equipment.)

8.

Install A/C service valve cap.

Description

INFOID:0000000006485596

MAINTENANCE OF LUBRICANT LEVEL

The compressor lubricant is circulating in the system together with the refrigerant. It is necessary to fill com-
pressor with lubricant when replacing A/C system parts or when a large amount of refrigerant leakage is
detected. It is important to always maintain lubricant level within the specified level. Otherwise, the following
conditions may occur.
• Insufficient lubricant amount: Stuck compressor
• Excessive lubricant amount: Insufficient cooling (caused by insufficient heat exchange)

Inspection

INFOID:0000000006485597

If a compressor is malfunctioning (internal noise, insufficient cooling), check the compressor oil.

1.

COMPRESSOR OIL JUDGMENT

1.

Remove the compressor. Refer to 

HA-32, "COMPRESSOR : Removal and Installation"

.

2.

Sample a compressor oil and judge on the figure.

Judgement result 1>>Replace compressor only.
Judgement result 2>>Replace compressor and liquid tank.

Perform Lubricant Return Operation

INFOID:0000000006485598

CAUTION:

If a large amount of refrigerant or lubricant leakage is detected, never perform lubricant return opera-
tion.

1.

Start the engine and set to the following conditions.
• Engine speed: Idling to 1,200 rpm
• A/C switch: ON
• Fan speed: Maximum speed set
• Intake door position: Recirculation
• Temperature setting: Full cold

2.

Perform lubricant return operation for approximately 10 minutes.

3.

Stop the engine.

4.

Lubricant return operation is complete.

Lubricant Adjusting Procedure for Components Replacement Except Compressor

REFRIGERATION SYSTEM SYMPTOMS

Trouble Diagnosis For Unusual Pressure

INFOID:0000000006485602

Diagnose using a manifold gauge whenever system’s high and/or low side pressure(s) is/are unusual. The
marker above the gauge scale in the following tables indicates the standard (usual) pressure range. Refer to
above table (Ambient air temperature-to-operating pressure table) since the standard (usual) pressure, how-
ever, differs from vehicle to vehicle.

are too high.

The pressure returns to nor-
mal soon after sprinkling wa-
ter on condenser.

Overfilled refrigerant.

Collect all refrigerant, evacuate 
refrigerant cycle again, and 
then refill it with the specified 
amount of refrigerant.

than the outlet of evapora-
tor.

• Low-pressure pipe is frost-

ed.

much (excessive flow of refrig-
erant).

Replace expansion valve.

High-pressure side is excessively 
high and low-pressure side is too 
low.

High-pressure pipe and upper 
side of condenser become 
hot, however, liquid tank does 
not become so hot.

Clogged or crushed high-pres-
sure pipe located between 
compressor and condenser.

Repair or replace the malfunc-
tioning parts.

High-pressure side is too low and 
low-pressure side is too high.

• The readings of both sides 

become equal soon after 
compressor operation 
stops.

• There is no temperature dif-

ference between high- and 
low-pressure sides.

Break-in Operation

When replacing compressor clutch assembly, always perform the break-in operation, by engaging and disen-
gaging the clutch approximately 30-times. Break-in operation increases the level of transmitted torque.

CHECK DISC TO PULLEY CLEARANCE

Check the clearance (B) between pulley assembly (1) and clutch
disc (2) along the entire periphery with a feeler gauge (A).

Replace compressor if specified clearance is not obtained.
