Note: General Motors vehicles are manufactured with fluorescent dye installed in the A/
C refrigerant system.
Perform an A/C system leak test to verify that the leak is coming from the A/C receiver
and dehydrator plug (1). Refer to Leak Testing (Fluorescent Dye Method) in SI.
Caution: Air Conditioning (A/C) desiccant must be replaced if the A/C refrigerant system
has been open to atmosphere for more than four hours, or if the A/C refrigerant oil has
been contaminated. Failure to replace the A/C desiccant will result in damage to the A/C
refrigerant system.
If there is a leak coming from the A/C receiver and dehydrator plug, replace the A/C
receiver and dehydrator using the service kit called out in this bulletin.
Important: When replacing the A/C receiver and dehydrator plug, apply a light coating of
poly-alkylene glycol (PAG) oil to the O-rings prior to installing the plug into the condenser.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
