LW2 V6-3.0L VIN R (2000)
GENERAL SYSTEM CONDITION - LOW REFRIGERANT CHARGE - L81
KEY:
POOR COOLING AT HIGHER AMBIENTS.
THEN:
System is operating with a low charge.
^
Leak test all components and connections.
^
If refrigerant charge level is unknown, reclaim, evacuate and recharge system with .95 kg (2.09 lbs.) of R134a refrigerant.
^
Run another performance test.
NORMAL SYSTEM PERFORMANCE SERVICE STALL - L61
IMPORTANT:
To ensure accurate pressure and temperature readings make sure the vehicle is properly set up to run the performance test. (Refer to vehicle set up
section in this manual.) All test parameters must be followed to obtain accurate readings.
IMPORTANT:
Use a refrigerant identifier to verify refrigerant purity. Non-condensable gases or refrigerant substitutes will affect system pressure/temperature
readings.
NORMAL SYSTEM PERFORMANCE SERVICE STALL HIGH HUMIDITY - L61
^
High humidity conditions affect system performance by increased heat load on system. This extra heat load will increase discharge pressure and
outlet temperature. High humidity is defined as a relative humidity higher than 70 percent at 21°C (70°F), 60 percent at 27°C (80°F), 50 percent at
32°C (90°F), and 40 percent at 38°C (100°F).
