Where is the low pressure port ?


That port would be located at the rear of the passenger side fender well under the hood. It's kind of against the firewall. Be carefull of moving parts as the front of the engine is right there. Good luck

Cant find the low port line on ac on a 2002 ford expedition i looked on all ac lines there is a green cap above the brake booster but that cant be it not a steel line its plastic and o


Hi, if your charge hose fits on the fitting under the green cap, then that is the right one. Plastic can handle the pressure on the low side. The low side port is always on the line that goes from the firewall to the compressor. So you can trace that line across the firewall and on to the compressor to make sure.

You have to locate the low pressure line and connector port. Trace the two lines back to the firewall that come from the compressor. You will find 1 port on each line. They are usually covered by a plastic cap of some type that unscrews. Your refill hose, assuming you have a standard refill can with attached gauge, will only attached to the low pressure side. The two ports are slightly different in size. The low pressure side should be the larger of the two lines you are tracing from the compressor.

Where is the freon refill located at in the ford 2000 expedition?


hi, the freon refill point you are looking for is on the accumulator. but you can't see it cause it's buried by the heater hoses, battery cables, and firewall mounted fuseblock. remove the fuse block cover, and get a bright flashlight, look just below the fuse block and you will see the cylindrical accumulator(aluminum canister looking) and the low side pressure port with the plastic cap on it.

Where is the low pressure ac port on an 1999 ford expedition 5.4l


If you find the big round silver thing (reciever/dryer) it is in it or in the same line nearby. Probably area of passenger side close to firewall. The low pressure side is the larger of the tubes.

2002 ford expedition air conditioner needs R 134 refrigerant. I cant seem to locate the service port.


The low pressure valve on the 02 expedition is located on the accumulator on the passenger side fire wall. The accumulator is underneath the battery relay and a grouping of wires. Had to squeeze hand underneath a heater2_bing.gif hose and an a/c line to remove cap and hook up hose. Nothing has to be removed to locate the valve just a little touchy feely. Valve faces a 45 forward toward the engine.

THIS IS DEPENDENT ON AMBIENT AIR TEMPERATURE , THAT IS TEMP OUTSIDE NEED TO GET TEMPERATURE PRESSURE CHART TO DETERMINE THIS NUMBER , ALSO LOW SIDE OR HIGH SIDE , LOW SIDE PRESSURE IS THE ONE I USUALLY USE TO ADJUST CHARGE , BUT AS I SAID IT IS DIRECTLY RELATED TO AMBIENT AIR SO THERE IS NOT A GIVEN NUMBER SHOULD BE ABLE TO GET CHART @ AUTO SUPPLIER OR JUST ASK ONE OF YOUR AC PEOPLE IF THEY CAN MAKE YOU A COPY OF ONE .
