Where is the air conditioning low pressure port on a 2007 Jaguar S Type?

On a 2007 Jaguar S-Type, the low pressure port for the air conditioning system is typically located on the larger diameter aluminum line that runs from the evaporator to the compressor. It can usually be found near the front of the engine bay, on the passenger side. To access it, you may need to move aside some components, but it’s generally identifiable by its blue or black cap. Always ensure the engine is off and the system is depressurized before attempting any service.
