Which Port for AC Refrigerant Recharge

[Director_Tann8]

Hey, hoping for a bit of advice here. My AC isn’t cooling at all, so I thought I’d try recharging the refrigerant myself before heading to the dealer for a full diagnosis. I’ve got a 2019 Niro EV EX Premium, and I believe it has the heat pump system.

When I popped the hood, I noticed two ports that look like they could be for recharging. One is back near the firewall (marked yellow), and the other is right at the front of the “engine” bay (marked green). I’m not sure which one is the right one to hook up the recharging hose. Has anyone done this before or know which port I should be using? Any tips or things to watch out for?!

Use the yellow-marked low-pressure port to recharge the refrigerant in your Niro EV. Watch out for overcharging and the sort of refrigerant you use. It's safer to have a dealer diagnose the problem if you're not sure.
