A/C Low side PORT???

[Tchao]

Hey guys,

The Expy's AC isnt getting that cold anymore. So I need to know where the low side port is.

All I can find for some odd reason is the High port, its right by the radiator on the battery side (passenger side)

Can you please tell me where the low side is.

Thanks,
San
