Where's the 2015 chevy traverse low pressure port located?

The low pressure port on a 2015 Chevy Traverse can be found on the line that runs from the compressor to the evaporator in the engine compartment. This is where You will need to connect a freon exchange machine if You plan on adding refrigerant to Your vehicle's AC system. It is a good idea to check this port as well if You notice that You have reduced cooling capacity. These have been known to be weak spots in the past where leaks can develop. I suggest that You also make sure that the cap is properly installed. If all of that is okay then You may have just loSTSome freon from Your system and will need to refill it.
