A/C System Performance
WARNING: This page is about a different car, the 2002 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
If ambient temperature exceeds 100°F (38°C), run engine at idle speed.
- Park vehicle out of direct sunlight. Connect manifold gauge set to service valves. Close all doors and windows. Insert thermometer in center vent.
- Place A/C-heater control panel at MAX A/C position and highest blower speed setting. Operate engine at 1500 RPM for 10 minutes to allow A/C system to stabilize.
- Temperature at center vent must be within 35-49°F (1.7-9.4°C). Ensure high side pressure is within specifications. See A/C SYSTEM HIGH SIDE PRESSURE SPECIFICATIONS table. Low side pressure must remain constant at 24-45 psi (2.0-3.0 kg/cm2 ) throughout normal operating range. If temperature or pressures are not as specified, go to TEST E: INSUFFICIENT A/C COOLING under SYMPTOM TESTS.
