Refrigerant is a formulated mixture/working fluid that transforms hot air into cold air in the car’s AC system. The AC system is a crucial component in ensuring the safety of your vehicle’s drivers and passengers. Therefore, it is essential to keep the refrigerant at its optimal level. If the refrigerant is low, it will be displaced by air and will degrade the performance of the car’s AC system. This may lead to symptoms such as lukewarm air, noticeable coolant leaks, and warning lights on the dashboard.

The best way to handle the issue is to drain the freon from your car’s AC system. The process is simple, but you’ll need a few tools such as a container to collect the freon, a hex key, and a wrench. You’ll also need a purity detector to ensure that the refrigerant you remove is pure. It is illegal in most states to allow the release of refrigerants into the environment, so it’s important to know that you’re working with the correct substance.

To begin, you’ll need to locate the low-pressure port. This is typically found on the larger-diameter line, known as the suction line. You can find the location of this port by referring to your owner’s manual or by visually inspecting the AC components under the hood. Once you’ve found the port, look for a cap that covers it and is typically labeled with “L” or “low.” Remove this cap to expose the low-pressure port.
