The low side is always on the line that goes from the compressor to the inside of the car or into the firewall.The high side and low side fittings are different sizes so you can't get them mixed up.

Where is the ac Low port 2007 ford edge?

The low pressure port is either on the black oblong canister or very close to it. Automakers usually put the high pressure side closer to the radiator. The ports are different sizes so the refill connections should not fit each other, making it harder to connect the wrong port.

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 the low pressure ac port on a 2000 ford explorer xlt

Yup, the last one should be the right one, but if you hear air seeping you will have to replace the valve on it. The valve is hard to find and your best bet is the dealer. It should be fairly inexpensive and comes off just like a tire valve. Once replaced, you can fit your a/c hose on the orifice a recharge it.

Which service port do I use to add coolant to the air conditioning, the one located at the rear of the engine compartment by the fire wall or the one up front by the radiator?

The low pressure port for recharging is usually the one near the firewall. That line will also go to a cannister and then into the firewall to the evaporator core. The one by the radiator is usually the high pressure side. Your connector will only fit the low pressure (correct) port for filling, as the 2 ports are different sizes.

D I Y a/c recharge Where are the a/c ports located

The low side port is located near the firewall at the back of the engine compartment near the right strut tower. It has a black plastic cover similar to a tire valve. Do not connect to the high pressure side which on my vehicle is located towards the front of the right side near the radiator. You will need R-134a and a connector kit. If you have leaks they should be corrected before recharging. Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

Where is ac charging port on a 1998 ford contour located

Either on the "dryer" which is the bottle shaped item usually next to the radiator or firewall or on the largest diameter a/c hose, not the smaller diameter. You will feel this hose get cold if you are on the right one. I'm guessing you have a standard recharge kit from Wal-Mart, AutoZone, etc. which consists of a pressure gauge, screw on tap, valve, hose with attached fitting if yours differs let me know before proceeding otherwise, first attach hose to the low pressure charging port on the refrigerant line. This will be on the larger tube usually near or on the accumulator. The silver aluminum cylinder with several wire connections and 2 black plastic covers which will be your quick connect connections the smaller diameter one will be your low pressure side. Be sure to wear gloves and eye protection!!!

Air Conditioning Low Pressure Line

The high pressure one is the closest to the A/C compressor. Therefore the one near the firewall would be the low pressure (behind the engine)

Why do u wanna know this since u can't fill it up urself?
