Usally freon is a coolant that has to be put in by a certified mechanic that has the means and applications to administer the coolant.

One eighteen ounce can can put your cars cooling system back on track. The easy instructions are great to follow with step by step instructions right on the can. The refrigerant can be bought at most auto parts stores and eliminates the mechanic from the equation if you follow the directions. The can of refrigerant comes with a hose hook up with a pressure gauge attached. The technical part is locating the right port to hook the hose of the refrigerant to.
I will lead you through the steps for a successful charging of your cars cooling system. Take a deep breath and we are on our way.
STEPS TO CHARGING YOUR CARS COOLING SYSTEM:
STEP 1) Look under the hood of you car on the left side of your cars engine. There should be two stainless steel lines coming from a stainless steel cylinder to your cars compressor. The two lines have plastic dust caps on them sometimes they are blue or black. Usally the black has the larger diameter tubing that runs between the evaporator and the compressor. This will be the port that you hook the refrigerant hose up to.
STEP 2) Start your cars engine after you have secured the hose hook up to the air conditioner line port. Once the cars engine is running, turn your cars AC on to Max cool. Shake the can of coolant well. The gauge on the can of coolant should read in the blue but if it is in the green your air conditioners pressure will be between 0-25 pounds per square inch. This means you will have to add refrigerant to the compressor.
If your cars air conditioner pressure is in the blue. The system has the proper amount of refrigerant and you do not need to add. If the gauge reads in the yellow you may want to seek professional help because refrigerant is not what is wrong with the unit and is probably something more technical and most likely something that you do not want to attempt to do on your own. The red on the gauge means do not add any refrigerant at all and to seek professional help.
STEP 3) If the pressure of your air conditioning system is in the green it means it is safe to add the refrigerant. You should wait for your air conditioning compressor to switch on before squeezing the trigger to add the coolant. When the compressor switches off then release the trigger and repeat until your pressure gauge on the coolant can says that the coolant is in the proper range. If the needle on the gauge is in the top part of the blue you have successfully charged your cars air conditioning unit.
STEP 4) Release the attachment from the tubing port and replace the dust cap back in it's proper place and you are done. The cars air should be cool and your compressor should cut off and on less often. If problems persist you should consult a mechanic or someone that has experience with air conditioning systems.
Sometimes these simple processes help the do it yourself people out there and can save you a lot of money if that is all your cars cooling unit needs. It is simple and self explanatory all you have to do is follow directions.
