Where is the low pressure tap on a 2001 XL7?

On a 2001 Suzuki XL7, the low pressure tap for the air conditioning system is located on the larger diameter refrigerant line, which runs from the compressor to the evaporator. Typically, this line is near the firewall on the passenger side of the engine bay. You can identify the low pressure service port by its blue cap, while the high pressure port has a larger, usually red cap. Always ensure the system is off and properly evacuated before servicing.
