Hello,

I have a 2014 LR4 and I'm attempting to recharge the AC. The car has multiple zones and uses 1234YF. There are two (green) ports very visible and they are both the same size. Does anyone know if one of these is the low side port or if these are both high side and the low side is elsewhere? If so, does anyone know where the low side port is? Thanks in advance!

 

I think you will find that under the caps, there are different sized fittings.
But that wasn’t your question. The low pressure fitting is connected to the low pressure line. The low pressure line is the larger diameter line.

Are you aware on how this system works? Over filling is just as problematic as the system being low. Moreover, the wrong fluid will muck everything up.

The workshop manual has many pages explaining the complexities of this system.
