Types of Car and Truck Air Conditioning Refrigerants
There are different types of refrigerants used, such as 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, then 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 it is likely time to upgrade the vehicle’s AC 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 are likely best.
Buying refrigerant and adding it to a car or truck is easy to do and falls in the DIY category.
R134a is by far the most common refrigerant used but be sure to double-check under the hood or google the type.
Take care when handling refrigerants. Also, remember Refrigerant refrigerant is a contaminant and can be harmful.
Never smoke around refrigerant as it can turn deadly when it burns and enters the lungs.
A burst of refrigerant will freeze anything close, including body parts, possibly causing frostbite.
Always wear goggles as a safety precaution. If in doubt, take it to a professional shop.
