There are three types of Freon variants that automotive companies use.

  • The second is the R134a. Chances are, this refrigerant is probably there in your car at this very moment. This is the most common refrigerant that was used since 1994. The R134a contains a tremendous amount of CFC-12 and HFC-23, and other greenhouse gases. However, due to its harmful nature, industries no longer use this refrigerant.
  • The third is the R1234yf, a newly introduced refrigerant that replaces the harmful R134a refrigerant. The majority of the counties use this variant of refrigerant for the vehicles. Therefore, it can be the best one you should use.

Preparing The Recharge Kit

As you unpack your kit, you’ll find a can of refrigerant, a flexible rubber hose, and a pressure gauge. Follow the instructions in the package to assemble the pressure gauge part of the kit. Usually, the hose is already attached to the gauge. Before you screw the gauge into the can of refrigerant, be sure to turn the gauge counterclockwise until it stops. There is a pin inside the assembly that pierces the can of refrigerant once everything is together tightly. This pin is controlled by turning the gauge clockwise until it pierces the can. But you don’t want to do this until you’re ready, so be sure to back it all the way out before you assemble everything.
