Where is the low-side A/C port located on my '97 3.8 Camaro? I need to recharge the system and I see two places to screw into; one looks like its connected to a bottle and the other is near the radiator... which one is it?


Thanks,
Mark

 

you want the high flow one, not the low. its on the left side if your looking at the engine right by the condensor thingy

 

DO NOT USE THE HIGH SIDE FOR SQUAT. DANGEROUS S***. you need the low side to recharge. normally they are by the bottle in a fat a/c line. the high side port is on the skinny a/c line. stay away from the high side!

 

yeah, he's right. i got mixed up for which one is which. i just did it using the low and it works.

 

low side = large diameter line and small port.
high side = small diameter line and large port.

High side is for closed valve pressure read only. If you attempt to open the high side it will fill and then explode the can your charging from. Only charge from the low side (suction) port.

 

mark reply........hope he didnt use the high side.

 

thanks guys, no I used the low-side. My uncle came over and he's HVAC certified so he help. Thanks for all the replies though.
