How do you add refrigerant to a 1995 Buick Century?
The low side line should be located right on the firewall towards the middle of the car. I just use two cans of 134a and a little blue hose. Any parts store should have those in a package deal. Turn on the ac and allow to run for 5 minutes or so to stabalize the system, then go ahead and add the freon.
Using a vacuum pump, you evacuate the refrigeration lines to get all of the moisture and air out of the line and verify that there are no leaks, then you add refrigerant, probably 134-A, and possibly oil charge if you determine that it is needed. You'll need to understand the concepts of refrigeration to get an idea of how much to add.
First off if it is low of refrigerant then it has a leak. It is illegal to add refrigerant to a A/C system without first repairing the leak. You have neither the tools nor the skill to repair the leak, and to add the correct amount of refrigerant. Take it to a professional shop with the proper equipment and knowledge to repair the system correctly.
If you are having to add refrigerant, then this means you have a leak, and you will be adding refrigerant again in a few months. It is illegal to add refrigerant to a system with a leak without first repairing the leak. So, my advice is to take it to a professional and have the leak repaired and refrigerant added with the proper equipment, which you do not have.
You don't. The 2000 Saturn refrigerant is not Freon R12 it contains R134a. Add it at the Low pressure port. You have a leak or it would not be necessary to add refrigerant. It is illegal to add refrigerant to a system with a leak without first repairing the leak. Take it to a professional and have the leak fixed.
Buy refill at local autoparts store and follow instructions. Follow tubes coming from your A/C compressor. There are two refrigerant tubes with test/fill valves, only one will take the fill can screw on filler attachment. FOLLOW DIRECTIONS!!! Car is running w/ A/C on high/max while you fill. Do I have to say this is all very dangerous?
I believe what you are asking is where do you charge an ac system with 134. I have a 90 buick lesabre limited and the charge port is located on the accumulator. It is a big silver canister that the refrigerant lines go to. You should see a charging port on the right of it if you are looking at it from the front of the car. I dont know what year your car is…
Check the refrigerant level. Your vehicle probably uses 134A refrigerant so it shouldn't be too expensive. If the refrigerant level is low, someone can add refrigerant for you or you can purchase the tools and do it yourself. Refrigerant is added with the engine running, and to the "low" side. Never allow the "High" side to be over pressure.
Generally you charge a refrigeration system by weight, not by pressure or temperature. Say, for example, if you were adding refrigerant to a system, you might add a pound of refrigerant. You wouldn't add it until it was at a certain pressure. As for a consumer AC system in a vehicle, I couldn't tell you how much to add. Look for a reference of the amount of refrigerant in the system and start by adding…
