The port will either be in the low press line ( large line ) or on the bottle shaped accumulator by the firewall.

SOURCE: low side port for air conditioner

If you are recharging the air conditioner - start at the A/C pump, and follow the lines up until you find a black round stub (this unscrews) and this is where you will re-fill (recharge) the A/C.

NOTE: It is recommended to have a professional (certified) mechanic recharge A/C systems, but is not necessary. (laws and regulations vary per state, city, county).

Please let me know if you need further assistance.

SOURCE: I need to locate the low side ac port. air

The easiest way to locate the low side charge port on any vehicle is to locate the A/C compressor, follow the "larger" of the two lines all the way back to the firewall. Some where along that line you will find the low side charge port.
Good luck.

Where is the low side port for ac charge located on engine for 2001 mountaineer


4.0L , 5.0L : Back near the firewall (Evaporator) above the accumulator/drier. The line will be cold /low pressure port.
Near radiator (Condenser) is hot/high pressure port

Be careful, if unsure do not risk it. If the system is leaking this will be a very temporary fix and probably needs the service of an experienced auto AC person.

Where is low preasure valve for air conditioner


Low pressure service port is located on the Accumulator ( Silver Cylinder ) where the low side A/C line domes from the compressor. Location is on the passenger side fender by your evaporator housing and blower motor housing.
Thank you for using fixya and don't over charge your system.

Where is air conditioner recharge port


remember you will always charge an air conditioner on the low side. which is always on the larger hose. there is a smaller one which is the high side so stay away from the small one.. look up near the radiator and see if you see the dryer which is about 3 inches across and 8 inches long and looks like a cylinder.. on this device there is a port where you can charge it .. also this year might be up near the firewall .. they change locations too often .. thanks and holler if you need more.
