2. Evacuate the system (see SYSTEM EVACUATION ).
3. Add the same amount of new refrigerant oil to the system that was removed

during recovery. Use only SP-10 refrigerant oil.

4. Charge the system with the specified amount of R-134a refrigerant. Do not

overcharge the system; the A/C compressor will be damaged.

Select the appropriate units of measure for your refrigerant charging station.

Refrigerant Capacity:

400 to 450 g
0.40 to 0.45 kg
0.9 to 1.0 lbs
14.1 to 15.9 oz

5. Check for refrigerant leaks (see REFRIGERANT LEAK TEST ).

6. Check the system performance (see A/C SYSTEM TEST ).

REFRIGERANT LEAK TEST

Special Tools Required

Leak detector, Honda Tool and Equipment YGK-H-10PM or commercially
available

1. Connect an R-134a refrigerant recovery/recycling/charging station (A) to the

high-pressure service port (B) and the low-pressure service port (C), as shown,
following the equipment manufacturer's instructions.

CAUTION:

Air conditioning refrigerant or lubricant vapor
can irritate your eyes, nose, or throat.

Be careful when connecting service equipment.

Do not breathe refrigerant or vapor.

NOTE:

If accidental system discharge occurs, ventilate work
area before resuming service.

Additional health and safety information may be
obtained from the refrigerant and lubricant
manufacturers.

2. Open high pressure valve to charge the system to the specified capacity, then

close the supply valve, and disconnect the charging station fittings.

Select the appropriate units of measure for your refrigerant charging station.

Refrigerant Capacity:

400 to 450 g
0.40 to 0.45 kg
0.9 to 1.0 lbs
14.1 to 15.9 oz

3. Check the system for leaks using an R-134a refrigerant leak detector with an

accuracy of 14 g (0.5 oz) per year or better.

4. If you find leaks that require the system to be opened (to repair or replace

hoses, fittings, etc.), recover the system.

5. After checking and repairing leaks, the system must be evacuated.

A/C SYSTEM TEST

PERFORMANCE TEST

The performance test will help determine if the A/C system is operating within
specifications.

1. Connect an R-134a refrigerant recovery/recycling/charging station to the high-

pressure service port and the low-pressure service port, following the
equipment manufacturer's instructions.

2. Determine the relative humidity and air temperature.
3. Open the glove box. Remove the glove box stop on each side, then let the

glove box hang down (see GLOVE BOX REMOVAL/INSTALLATION ).

4. Insert a thermometer (A) in the center vent.

CAUTION:

Air conditioning refrigerant or lubricant vapor
can irritate your eyes, nose, or throat.

Be careful when connecting service equipment.

Do not breathe refrigerant or vapor.

NOTE:

If accidental system discharge occurs, ventilate work
area before resuming service.

Additional health and safety information may be
obtained from the refrigerant and lubricant
manufacturers.
