You can find the correct refrigerant for your car in the owner's manual or on a sticker in the engine bay. If you can't find it, a local mechanic can help. Your car's AC system may need to be replaced if it's leaking refrigerant, but regular maintenance and inspections can prevent this.
Here are some common types of refrigerants used in cars:
- R-12 (banned due to environmental concerns)
- R-134a (widely used, but can harm the environment)
- HFO-1234yf (eco-friendly option, becoming more popular)
Most modern cars use R-1234yf, a hydrocarbon refrigerant that doesn't deplete the ozone layer. If your car uses an older refrigerant, you may need to convert it to R-134a or R-1234yf.
