Air conditioning


When an vehicle's air conditioning system has not been used for several months, the seals within the system start getting dry. I've never worked on a Peugeot 206 or any other peugeot before, that's why I had no idea where the low pressure ac port was. The high pressure ac port is the easiest to locate, because it is in the engine compartment, facing the car from the front, on left side of the radiator. The low pressure ac port is in the engine compartment, facing the car from the front, to the back in the center, under the windshield. The low pressure ac port and the high pressure ac port both have black dust caps. The low pressure ac port is the smaller of the two.

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 side port for th AC located? Found two ports, one on compressor and one located on line near compressor.


The a/c recharge kit will only fit on the low side. So you can't get a can to fit on the high side.

Where does the freon go for a 99 expedition


Hi .. I just ran into the same problem .. I have a 2000 Expedition with the 5.4L engine .. the low side port is located on the passenger side of engine compartment just below the black metal bracket that contains electrical connections right in front of the firewall... you have to reach under this and locate the low side (larger line) and feel for the connection .. it is right in front of the accumulator .. There are two heater hose that hide the port .. you have reach under these to unscrew the port cap which is black .. you'll have to do this by feel .. I have found that you can by R134A charge with dye and leak sealant helps with small leaks .. if the system takes more than two cans be usre to add refrig. oil .. hope this helps

AC Low Pressure location on 2004 Chevy Suburban


You find the AC low pressure at the top of the compressor, orientated toward you , facing the front of the vehicle. You can also follow the compressor line to reach the port.

The valve is covered a plastic cap covering it.
Near the compressor you find two ports, the high port and low port.

To find out which one is the low port, run the air conditioner for a couple of minutes withthe engine on.
Then turn off the care and touch the lines from compressor to the two ports covered with plastic caps. Only one of the pipes will be cold, the cold line will lead you to the low port.

Regards.

Where do I recharge ac at


there are 2 ports one for low pressure and one for high pressure. the low pressure is bigger in diameter and is usually close to the dryer and or fender and firewall. the high pressure is near the condensor on the fron of the vehicle. if there are caps for the ports low will be blue and high will be red. low side pressure should be 35-50 psi and high pressure should be 135-150 psi
