•Channel-plate construction helps provide a high refrigerant contact surface area
•Vacuum-brazed, corrosion-treated, and leak-tested to help provide trouble-free operation
•GM-recommended replacement part for your GM vehicle’s original factory component
•Offering the quality, reliability, and durability of GM OE
•Manufactured to GM OE specification for fit, form, and function

Signs of wear for A/C components include but are not limited to:
•Lack of or insufficient interior cabin cooling
•Excessive clicking sounds, unusual noises, or growling when using the A/C system
•Internal compressor fault
•A/C clutch or electrical circuit failure
•Low refrigerant levels

Your A/C system must be maintained with the correct level of refrigerant and appropriate pressure to work properly. An A/C system leak, which could result in incorrect fluid or pressure levels, could potentially damage or interfere with the performance of your A/C system. This would result in lack of or insufficient cooling performance. Common causes of A/C system leaks include:
•Worn or damaged service valves and caps
•Worn hoses
•Loose connections
•Seal failures
•Worn or damaged compressor shaft seal, evaporator, condenser, or compressor seals
•A/C system component corrosion
•Missing service cap

To check your A/C system for leaks:
•Use a leak detection dye. Be sure to use the dye that is specified for use with your systems oil and refrigerant type
•Look for dirt or contaminant build up around hose or line connections. This could be a sign that oil, which would attract and hold contaminants, is leaking out of the connection
 

Your A/C system is a sealed system, which includes different components connected by hoses, tubes, or lines. To keep the system leak free, inlet and outlet fittings have O-rings or seal washers, and the lines have leak-free fittings. To help prevent leaks in the A/C System, follow these guidelines when servicing connections:
•Use the proper O-ring for the system
•Thoroughly clean all fittings and do not over torque beyond what is recommended
•Always lubricate O-rings with clean refrigerant oil
•Always replace sealing caps on service ports
•Recover refrigerant from the system when or if necessary
•Keep dirt and foreign material from all sealing surfaces
 

Q: Are there different types of refrigerant used in A/C systems?
A: Yes. Refrigerant has changed multiple times over the years, be sure to have the approved refrigerant for your system.

Q: Can I properly charge my A/C system with a can of over-the-counter refrigerant?
A: No. Using cans of refrigerant may add a boost to the A/C system temporarily. To properly charge your vehicle’s A/C system, have it serviced by a certified technician.
