Where is the low side ac port on a 2002 Acura RSX?

The low side AC port on a 2002 Acura RSX is located near the front of the engine bay, typically on the larger diameter aluminum line that runs from the evaporator to the compressor. It is generally found close to the driver's side of the engine compartment, near the firewall. Look for a port with a plastic cap that is often blue or black, which is used for recharging the AC system. Always ensure the engine is off and the AC system is properly discharged before attempting any work on it.
