SOURCE: ac low side service port location

Your service port will always be in the larger line of the two .. which is low pressure side. It might be in the dryer also which is low side.. your dryer is about 3 inches across and 8 inches long and also has your pressure switch for the AC compressor in it.. holler if you dont find it now... thanks Jerry

SOURCE: i need a diagram of the A/C low pressure port on

Find a shiny aluminum canister under the hood thats bigger than a soda can and follow the tubing that comes out of it back towards the front, you will come to a valve similiar to an air valve stem on a tire. The valve has a black plastic screw off cap. That is the low pressure port. The high pressure port is located behind or near the a/c compressor

Finding low a/c port on 2012 dodge grand carvan

The low ac port is back near the firewall slightly to the driver side. It's kinda hidden by the overhang of the cowl. If you look at the firewall for where the aluminum lines go into the cabin you can't miss the AC port. The high side port is under the power steering reservoir on the passenger side near the motor mount.

Where is the low pressure ac port

Not positive for this model, but usually passenger side, near the firewall, inline and perpendicular to a silver tube about the size of an average man's pinky finger, with a plastic cap that is either black or blue and has a large "L" molded into the top. Likely half-hidden behind hoses, tubes, wires, etc. Alternative location is near the radiator, same side.

Where is the ac low pressure port located on a 2000 chevy s10?

It's the port on the accumulator. The silver tank attached to your fan box. The low side of your a/c system is always going to be the larger hose.

I can't find the low port on the ac. I am trying to charge it

The charging port for this van is hidden good. Take the breather off. reach up under the dashboard just a little to the right and up from the breather...unless it is retro fitted... you will need an adapter but you can feel the port and will probably have to charge it by feel since it is so hidden.
