INSPECTION
Oil Specification
1. The HFC- 134a system requires synthetic (PAG) compressor oil whereas the R- 12 system requires mineral
compressor oil. The two oils must never be mixed.
2. Compressor (PAG) oil varies according to compressor model. Be sure to use oil specified for the model of
compressor.
Handling of Oil
1.The oil should be free from moisture, dust, metal powder, etc.
2. Do not mix with other oil.
3. The water content in the oil increases when exposed to the air. After use, seal oil from air immediately. (HFC - 134a
Compressor Oil absorbs moisture very easily.)
4. The compressor oil must be stored in steel containers, not in plastic containers.
Compressor oil check
The oil used to lubricate the compressor is circulating with the refrigerant.
Whenever replacing any component of the system or a large amount of gas leakage occurs, add oil to maintain the
original amount of oil.
Oil total volume in system:
120±10cc (4.05±0.34 fl.oz)
Oil Return Operation
There is close affinity between the oil and the refrigerant.
During normal operation, part of the oil recirculates with the refrigerant in the system. When checking the amount of
oil in the system, or replacing any component of the system, the compressor must be run in advance for oil return
operation. The procedure is as follows:
1. Open all the doors and the engine hood.
2. Start the engine and air conditioning switch to "ON" and set the blower motor control knob at its highest position.
3. Run the compressor for more than 20 minutes between 800 and 1,000 rpm in order to operate the system.
4. Stop the engine.
Replacement of Component Parts
When replacing the system component parts, supply the following amount of oil to the component parts to be installed.
Component parts to be installed Amount of Oil
Evaporator 50 cc (1.70 fl.oz)
Condenser 30 cc (1.02 fl.oz)
Receiver/dryer 30 cc (1.02 fl.oz)
Refrigerant line (One piece) 10 cc (0.34 fl.oz)
For compressor replacement, subtract the volume of oil drained from the removed compressor from the specified
volume, and drain the calculated volume of oil from the new compressor:
The specified volume - volume of removed compressor = volume to drain from the new compressor.
Even if no oil is drained from the removed compressor, don’t drain more than 50cc from new compressor.

INSPECTION
1.Check the condenser fins for clogging and damage. If clogged, clean them with water, and blow them with
compressed air. If bent, gently bend them using a screwdriver or pliers.
2. Check the condenser connections for leakage, and repair or replace it, if required.
REPLACEMENT
CONDENSER ASSEMBLY
1. Recover the refrigerant with a recovery/ recycling/ charging station (Refer to HA - 8).
2. Disconnect the negative ( - ) battery terminal.
3. Remove the radiator. (Refer to EM group)
4. Remove 2 bolts, and then remove the condenser (A) by lifting it up. Be careful not to damage the radiator and
condenser fins when removing the condenser.
5.Install in the reverse order of removal, and note these items :
a. If you're installing a new condenser, add refrigerant oil ND- OIL8.
b. Replace the O - rings with new ones at each fitting, and apply a thin coat of refrigerant oil before installing them.
Be sure to use the right O - rings for R- 134a to avoid leakage.
c. Be careful not to damage the radiator and condenser fins when installing the condenser.
d. Be sure to install the lower mount cushions of condenser securely into the holes.
e. Charge the system, and test its performance. (Refer to HA - 9)
DESICCANT
1.Remove the condenser, and then remove the bottom cap (B) with L wrench (A) from the condenser.
TORQUE: 20~25N.m (2.0~2.5kgf•m, 14.5~18.2lb - ft)

2.Remove the desiccant (A) from condenser using a long nose plier. Check for crumbled desiccant and clogged
bottom cap filter.
3.Apply air conditioning compressor oil along the O - rings and threads of the new bottom cap.
4. Insert the new desiccant into the receiver drier tank. The desiccant must be sealed in vacuum before it is exposed
to air for use.
5. Install the new bottom cap to the condenser.
a.Always replace the desiccant and bottom cap at the same time.
b. Replace the O - rings with new ones at each fitting, and apply a thin coat of refrigerant oil before installing
them. Be sure to use the right O - rings for R- 134a to avoid leakage.
c. Be careful not to damage the radiator and condenser fins when installing the condenser.
d. Be sure to install the lower mount cushions of condenser securely into the holes.
e. Charge the system, and test its performance. (Refer to HA - 10)

REPLACEMENT
1.Discharge refrigerant from refrigeration system (Refer to HA - 8).
2. Replace faulty tube or hose.
Cap the open fittings immediately to keep moisture or dirt out of the system.
3. Tighten joint of bolt or nut to specified torque.
Connections should not be torque tighter than the specified torque.

4. Evacuate air in refrigeration system and charge system with refrigerant (Refer to HA - 9).
Specified amount: 800 ± 25g
5. Inspect for leakage of refrigerant.
Using a gas leak detector, check for leakage of refrigerant (Refer to HA - 9).
6. Inspect A/C operation.
