Hello,

Before I go spend a few hundred dollars to diagnose my AC cooling problem I wanted to try to recharge my wife’s car first.

I have a 2016 range rover sport diesel. I believe I found the AC lines one being thicker than the other. Both lines are on the driver side right over the wheel well with the ports sticking out. Both ports have green tabs on them but no indication of one being low or high pressure. I assumed The thicker line is the low pressure however when I tried to put the AC charging tool connector on the low pressure port it seem like it didn’t want to fit. If I apply a little force, it seemed like you wanted to go over however I wanted to make sure that’s the right port before I continue.
