The low preasure valve is located on the line coming off the ac compressor, if you look down from the front at the compressor and follow the top line out about 4 inches you will see it, good luck.

If the compressor will run turn it on and let it run for a few minutes, the line that gets cold is the low pressure side, this is usually the one closest to the firewall. The reason that they are 6 inches apart is that they are on opposite sides of the orfice tube, hence one is high pressure and one is low.

Where do I add freon on a 2006 Ford Mustang GT?


If your system is blowing warm I would recommend having the system evacuated and check for leaks. Just adding Freon will not give you ice cold A/C. There are two valves, low side and high side. Usually the plastic caps are blue for low side, red cap for high side. If you use a commercial A/C machine to service the vehicle, both valves are connected to check pressures in the system and also to fill the system with the correct amount of Freon. The low side (blue) is located at the firewall near the dryer and the high side (red) is usually on the passenger side near the radiator.

Where is the ac port located to add freon


On a 2002 Mitsubishi Montero LTD, the a/c charging port is between the battery and the windshield. It is the port that has a cap labeled with an "L" (Low Side).

When the a/c is on, "L" (Low Side) gets cold while the "H" (High Side) gets hot.

Make sure you use the Low Side (cold) for adding Freon.

(note: over the counter freon kits should not fit the High Side port anyways) 6d9ed8b1-112d-471e-93a4-44bee9a08459.jpg

Where do you put the A/C fluid in a 1992 BMW 325is?


1992 is still probably set up for R12 refrigerant. You really need to get it converted to R134a, but there should be 2 valves located in the "hard" lines under the hood-1 for high pressure, 1 for low pressure. The freon goes into the low pressure side. Crank car and turn A/C wide open. The connector for adding the froen should only fit the low pressure side.

LOCATION OF LOW PRESSURE AC VALVE ON 1992 FORD ECONOLINE 150 TO CHARGE AC


Valve is between accumulator and evaporator on the passenger side. Your van originally came with R-12 freon, so you will need to verify that it has been converted to R-134 before adding freon. The different gasses (and especially the lubricating oils) do not mix well.

My ac blow out hot air and i want to put freon in my self and want to know how


Adding freon will not correct the problem. If you need to add freon, you have a leak, and you have moisture in the system, the leak should be located, mositure removed, then freon added. But to answer your question. Open the hood on, the left side you will see a round object called a dryer, you will see two pipes coming from it, one at the top and one at the bottom. The smaller is the high side, the larger is the low side. Obtain a can of freon either R-22 or 134a with an adapter for installing the freon. Turn the engine on, turn the AC to high. Add the freon to the ac using the low side.

Adding freon to 98 Isuzu Amigo


You need to add the freon on the low side which is usually indicated by a blue cap. The red cap is the high side port. Never add freon using the high side port. Typically if you are buying a guage set from your local auto parts store, it will only attach to the low side service port because they are diffent types of connections. Another easy way to tell is to turn your AC on and feel the lines that the ports are attached to. The low side should be cold/cool and the high side will be hot.

#1 you will need r134a freon. #2 the low side service port is located right at the firewall where tha line goes to the evaporator. #3 if wou bought a can of 134a freon with a hose that will hook to it, it will work. all service fittings for 134a freon are the same even though the high side and the low side will always differ
