A/C System Performance
WARNING: This page is about a different car, the 2001 Suzuki Vitara, 2001 Suzuki Grand Vitara, 2000 Suzuki Vitara, and 2000 Suzuki Grand Vitara. However, it is still accessible from the selected car via links, so may be relevant.
- Park vehicle out of direct sunlight. Warm engine to normal operating temperature and run at 1500 RPM. Set A/C controls to recirculated air, panel (face) mode, full cold, and A/C switch on. Verify A/C compressor and condenser fan are on.
- Set blower/fan on high speed. Open hood, windows and doors. Operate system until refrigerant pressures stabilize. Insert thermometer in center vent, and measure air discharge temperature. See A/C CENTER OUTLET VENT TEMPERATURES table. Temperature must be as specified at center vent, with high side low pressures within specification. See A/C REFRIGERANT SYSTEM PRESSURES table.
