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.

How do i charge the airconditioner

On a Traverse the low side service port can be found on the return tube between the radiator and the engine down by the compressor. It is almost directly below the high side port ( about 2' below it).

I want to know where is the location of an ac low service port?

Find the compressor and follow the thicker line/hose coming from it. On an A/C System, the Fat Line is the Suction or Low Pressure Line and the Skinny Line is the Hi Pressure Line. The Low Pressure Service port is usually located by the passenger side fender well next or on top of the filter/receiver/dryer (a metal cylinder device). The Low and Hi pressure service ports are different so there is no way you can hook up wrong the charging hose.
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

Where is the low pressure side service port on a 2006 Dodge Ram with a 5.7 liter Hemi? Thank you.

Find your A/C compressor and follow the larger of the two lines back to the fire wall and you will find the low pressure port for charging. It should have a blue screw on cap. Make sure you replace the cap when charging is complete as the cap is considered a seal for the system.
Good luck.

Re-charge a/c in a 98 ford escort zx2

Your low side should have a "blue cap" on it. If it does not, it is located on the passenger side of the vehicle near the firewall.
