Hyundai Elantra: Refrigerant label

The refrigerant label is located on the underside of the hood.

The refrigerant label on your Hyundai Elantra provides vital details about the type and quantity of refrigerant used in the air conditioning system. This information ensures that technicians use the correct product and follow safe procedures when servicing the system. Using incompatible refrigerants or overcharging the system can cause poor cooling performance or even compressor failure. The label is usually found in the engine bay or near the A/C components. It also contains safety warnings related to pressure and environmental compliance. Maintaining the integrity of this label helps preserve comfort and protects sensitive components from damage.
