Types of Car and Truck Air Conditioning Refrigerant
There are different types of refrigerant used such a R-134a which is used on newer cars and R-12 which was used in the 80s and 90s.
If your car or truck was made after 1994 than it likely uses R134a.
Before 1994 R-12 was the main Refrigerant used in cars and trucks.
If your car uses R-12 it can no longer be bought and likely time to upgrade the vehicles A/C system.
Most shops recommend upgrading an R-12 system to the new R-134a which can be a costly upgrade.
To find out the type of Refrigerant your car uses look under the hood for a label or simply Google your make and model for the Refrigerant type used.
How To Add Refrigerant to a Car or Truck Air Conditioning System
Refrigerant can be bought in single cans or as a kit that will have a hose attached to it.
The single cans cost less but will need a hose to add refrigerant to a car or truck.
- If you have a single vehicle a kit with a hose already attached is likely best.
- If you plan to add refrigerant to many vehicles the single cans with a detachable hose is likely best.
