It is located behind the AC compressor. When you look down from the driver side front fender you won't miss it.
The low pressure AC port on a 2000 Buick Century is located on the accumulator. It is used to fill the system with refrigerant and to check pressure levels.
The freon fill valve on an International 4700 truck is typically located on the refrigerant lines near the compressor. Look for two service ports: the low-pressure side is usually on the larger diameter line, and the high-pressure side is on the smaller line. The low-pressure fill valve is the one you'll use for adding refrigerant. Always ensure the engine is off and the system is properly serviced to avoid any hazards.

The Freon is added through the low side ac port. Using the proper type of Freon and a gauge, fill the system to the recommended pressure.
To fill refrigerant (commonly referred to as Freon) in an air conditioning system, first ensure the system is turned off and the appropriate safety gear is worn. Connect a refrigerant gauge set to the service ports, usually located on the outdoor unit. Open the valve on the refrigerant canister to allow the refrigerant to flow into the system while monitoring the pressure gauges to ensure proper levels. Always refer to the manufacturer’s specifications and consider hiring a certified technician for this process, as handling refrigerants requires expertise and adherence to environmental regulations.
R-134A
It is called refrigerant. Take it to a professional to repair the leak as you have one if it is low of refrigerant. He will then fill it up.
Do not add refrigerant. You must completely evacuate the system, then fill it _by_ _weight_ to prevent overcharging. Overcharging can cause leaks and/or compressor failure.
To fill the freon and oil in an empty compressor for a 2001 Kia Spectra, first, ensure the system is evacuated and properly sealed. Connect the refrigerant canister to the low-pressure service port and turn on the AC to allow the compressor to draw in the refrigerant. For oil, you can add the specified amount of PAG oil through the service port using an oil injector or directly into the compressor before installation. Always refer to the vehicle’s service manual for the correct quantities and types of refrigerant and oil.
Any auto parts store will carry an AC recharge kit. You should buy the refrigerant R-134a, and a hose that will connect to the AC line on your engine and to the AC can of refrigerant. It is best to buy the hose with a pressure gauge so you do not overfill the refrigerant. In your engine compartment there is a silver tube that runs from the AC compressor to the firewall. There will be a blue cap on the hose that has a L or says LOW. This is the low side and you MUST put the refrigerant in this line. Hook up the AC can to the LOW line and start your engine with the AC on full blast. Check the pressure gauge and if it is low open the valve to add AC refrigerant. Fill until the can is empty or the gauge says it is full. Enjoy
To add freon to a Hyundai Accent, first ensure the engine is off and the AC system is off. Locate the low-pressure service port, typically found on the larger of the two AC lines. Attach the refrigerant can's hose to the port, then start the engine and turn on the AC to the maximum setting. Open the valve on the refrigerant can slowly, monitoring the pressure gauge to avoid overfilling, and fill until the recommended pressure is reached. Always wear safety glasses and gloves when handling refrigerants.
