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.
Connect a freon gauge and can to the low side AC port. Start the car and turn the AC on high. Open the freon valve and fill the system to full on the gauge reading.
To fill freon in an AC unit, you need to first locate the service valves on the unit. Then, connect a charging hose to the low-pressure service valve. Next, slowly add the appropriate amount of freon to the system while monitoring the pressure levels. It is important to follow safety guidelines and regulations when handling freon.
right on the back of the compressor. low side top, high side under it
Under the hood on the passenger side towards the back of the engine compartment.
Use a gauge to see how full the system is. Check the fill valve for ant obstruction or damage. While the system could be over full, the most common cause is the fill valve being damaged, or the fill hose not connecting properly.
Connect freon gauges and a freon container to the low side ac port of the 1991 Integra. With the engine running and the ac on high, open the freon valve to fill the system until the gauge reads full.
To fill an AC system with freon, you will need to locate the low-pressure port on the system, connect the freon canister to the port, and slowly release the freon into the system while the AC is running. It is important to follow the manufacturer's instructions and safety guidelines when handling freon.
Same as any other car...attach fill hose fitting to the low pressure side of the system (it won't fit on the high pressure side fitting) and open the fill valve.
Connect a freon gauge and tank to the low side ac port on the 97 Park Ave. with the ac on high and engine running, open the freon valve. Fill the system till the gauge reads full.
Typically near the accumilator, which is the aluminum vertical capsule near the passenger side of the firewall. The low fill valve will be on a line going to the accumilator.
Is the fill valve leaking in your plumbing system?
The line that you fill freon to in a car is known as the fill line. Going past the line can cause overflow, or even damage your vehicle.
