Freon is R-12 refrigerant. Regulated due to involvement in ozone depletion. Which means EPA licensing and you can't just buy it at Wal-Mart. If it's a recent model, it'll contain R-22 refrigerant. Look for a label that tells you what's in and capacity of system. You can buy R-22 refills at box stores but be sure the carrier oil is compatible. However a small cooler might not have been designed to be serviceable. Anyway look for two plastic screw caps for high or low side then use a pressure gauge for car AC from Wal-mart, compare two pressure

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

How do remove the pressure ,before you add r34 cooler

you never work from the high pressure side of an a/c system. EPA requires it to be recycled, freon is removed using a vacuum tool on the low port until the system holds vacuum for 5 minutes. Then the recycler is removed and freon is added. You mean R134 right?

Diagram on how to install freon for air conditioning

freon is added though the suction side service port. if you don't have a manifold gauge set to check system pressures first then you might be doing more harm than good. if you took the system apart for any component change, then you will need to replace the drier/reciever and evacuate the system using a vacum pump before adding freon.

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.

How to add freon on a 1996 mercedes c220

The high side is on the driver's side of the condenser. the low side is usuall in line with the fuel cooler hose in the left side of the engine compartment. They are somtimes placed near the a/c compressor on the low side (suction) hose.

My air conditioner won't blow cold air. It just blows air.

Hello I'm a M.B. tech. 1st you need to know why the freon is low. Hopefully it just needs to be serviced. There is a component located in the lf of the engine compartment called a receiver drier. It soaks up the moisture in the freon so the gases can work the way they are supposed to. On this unit there should be 2 switches(I believe they were combined into one switch in 98. 1 switch is a temp switch that operates your electric fans, the other is a compressor cutoff switch. Assuming the compressor is not coming on-take a fused wire and bridge the 2 contacts- If the compressor does not come on at all there is another problem(it is not low on freon. On the condenser there is a high side port(it is the bigger of the 2)By the brake master Cyl.(lf of the engine compartment thereshould be a smaller low side valve in line with the fuel cooler hose. Usually you can hook up a machine to the low port and **** freon in through that port. Assuming you do not have a refrigerant machine. It is very self explanatory on the bottle of r 134a refrigerant which can be purchased at your local auto supply store. I would start with 1 lbs. and add dye with the freon in case there is a big leak. If the system is overcharged it will not cool properly. I believe the system capacity is approx. 2 lbs. Add a few ounces after the first pound until a/c system is cooling properly and the electric fans are also coming on when the system gets to high. If you get a can with a good Gage set on it you should see the high side between 150 and 2000 psi(fan coming on at max. press.) also the low side should read about 35. It is about the temp of the evaporator which is i=located in the dash and the blower blows through this component out through the vents. Hopefully I have been helpful.
