Where is freon put in a Hyundai Elantra?

Freon is typically not used in Hyundai Elantras or other modern vehicles. Newer vehicles generally use a different type of refrigerant, known as R-134a. The location of the refrigerant port for an R-134a system can vary depending on the specific model and year of the vehicle. In some cases, the port may be located on the low side of the system, which is closest to the compressor. In other cases, it may be located on the high side of the system, which is closer to the condenser. It's important to refer to the vehicle's owner manual or a qualified technician for specific information on the location of the refrigerant port.
