3. Bring the refrigerant system up to operating temperature and pressure. This is done by allowing the engine to run at idle under the following
conditions for five minutes.
a. Front windows are open.
b. Transaxle in Park.
c. Front heater-A/C controls set to outside air, full cool, panel mode, blower high, and compressor engaged.
d. If the vehicle is so equipped, the rear heater- A/C controls must be set to full cool and blower high.
4. Raise the liquid line (discharge) pressure to about 1793 kPa (260 psi) by placing a piece of cardboard over part of the front side of the condenser.
To place the cardboard properly, remove the upper radiator sight shield from the front fascia. Cover only enough of the condenser to raise and
maintain the liquid line pressure at the specified level.
5. Observe the liquid line (discharge) pressure and liquid line temperature. Using the Charge Determination Chart, determine whether the refrigerant
system is operating within the Proper Charge Range.
a. If the refrigerant system is operating in the Undercharged area of the chart, add 0.057 kilogram (0.125 pound or 2 ounces) of refrigerant to
the system.
b. If the refrigerant system is operating in the Overcharged area of the chart, reclaim 0.057 kilogram (0.125 pound or 2 ounces) of refrigerant
from the system.
6. Recheck the system charge level following each refrigerant adjustment. Continue this process until the system readings are in the Proper Charge
Range area on the Charge Determination Chart.
