GMC Terrain: 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. It should only be replaced by a new evaporator to ensure proper and safe operation.
During service, all refrigerants should be reclaimed with proper equipment. Venting refrigerants directly to the atmosphere is harmful to the environment and may also create unsafe conditions based on inhalation, combustion, frostbite, or other health-based concerns.
The air conditioning system requires periodic maintenance. See Maintenance Schedule.
Passenger Compartment Air Filter
The filter removes dust, pollen, and

air that is pulled into the vehicle.
The filter should be replaced as part
of routine scheduled maintenance...
