Air Conditioning Refrigerants
Not all air conditioning refrigerants are the same.
If
the air conditioning
system in your vehicle needs refrigerant, be sure
the
proper refrigerant is
used. If you’re not
sure,
ask your GM dealer. For additional information, see
your “Warranty and Owner Assistance Information” booklet.
Refrigerant should be added only by a qualified
A/C
technician.
