Chevrolet Silverado 2019-2026 Owners Manual / Climate Controls / Maintenance / Service

All vehicles have a label underhood that identifies the refrigerant used in the vehicle. The refrigerant system should only be serviced by trained and certified technicians. The air conditioning evaporator should never be repaired or replaced by one from a salvage vehicle.
