In this video I show you, step by step, how to add refrigerant gas to your car when the air conditioning does not cool or cools little, from your own home, step by step for little money, buying just a gas refill bottle for a few €22. To do this, you must have a pressure gauge with adaptable nozzles for this type of R134a refrigerant gas for cars. If you don't have the pressure gauge on Amazon, you can get it for €16 and you'll have it forever.

NOTE: R134a refrigerant gas is normally the one used in cars until the year 2018.

As of 2018, the type of refrigerant gas that has been used is R1234yf. These two types of gases are not compatible or miscible. Before adding gas to your car, make sure what type of refrigerant gas it uses.

This operation is the first time I've done it, so in the video I explain in detail and step by step, the procedure and the different temperature and pressure values of the circuit at all times so that you can have all the information.

I have also edited a second video, with all the temperature and pressure values of the low pressure refrigerant circuit, of the other cars that I have in the collection at home, so that you can see the differences.

The link to the second videos of the values when filling the refrigerant gas of my cars that are:
