Preparing the Refrigerant

You’ll need to get the appropriate refrigerant for your vehicle. R134a is used in every car made after 1995. Older versions employ 12. If your own car belongs to the latter group, you must take it to a mechanic.

Temperature control is the most crucial aspect of car air conditioning. You must use a thermometer to measure the surrounding temperature. Why? due to the fact that the refrigerant uses up various amounts of space in the container and the air conditioning system depending on the temperature.

Dealing with The Port

Now find the air conditioning system’s low-side service port. Simply follow the lines that emerge from the compressor until you reach a nozzle that is located at the rear of the vehicle. Remove the cap and use a piece of rag to wipe off the port, the line, and the cap. If required, wipe with brake cleaner.

The charging hose should now be linked to the port with the nozzle of the refrigerant container at the other end. If the kit includes a gauge, attach it to the gauge before the nozzle. Allow enough time so that the can remains outside the engine compartment. Keep checking the surrounding pressure throughout.

Refrigerant Filling

Till the seal is opened, turn the can’s valve. The moment the seal is broken, the refrigerant will be discharged. Hold the container firmly in place as the refrigerant runs through. As the gauge shows, keep an eye on the outside pressure.

Fill the tank as necessary until the gauge reads full pressure. You will be able to simply identify any leaks on the line if there are any. You’ll need to take your car to the mechanic if that’s the case. If not, just snap the lid shut once the refrigerant has been poured in. Your automobile’s A/C is back and cooling your car perfectly.
