Air Conditioning System Performance Check

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2015 Jaguar XFR, 2015 Jaguar XF, 2014 Jaguar XFR, 2014 Jaguar XF, and 2013 Jaguar XFR. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Normal pressures for a correctly charged and working system are 1.0 bar to 2.0 bar (low pressure system) and 11.0 bar to 15.0 bar (high pressure system).
Normal temperature (measured at the center air vent) for a correctly charged and working system is approximately 2°C to 7°C when the ambient temperature is 20°C.

When a failure symptom has been reproduced, refer to the SYMPTOM CHART . After completing a repair, the air conditioning performance check should be repeated to confirm that the repair is successful.

Close the valves on the air conditioning station
Connect the air conditioning station to the vehicle charging ports
Check that the gauges register pressure
Open all doors and the tailgate
Start the engine
Set the temperature to the lowest setting (all zones)
Set the blower speed to maximum
Set the recirculate switch to on
Set the air conditioning to on and check that the air conditioning compressor clutch engages and that the gauges register a change in pressure
Insert a temperature probe into the center air vent
Raise engine speed to 1500rpm and maintain this speed for 5 minutes
Check the pressure gauge readings
Check the temperature reading
