Recharging The A/c System CAUTION: The high side of the A/C system is under considerable pressure. If a can of refrigerant is connected to the high side service fitting, it may explode! The system must therefore be recharged by using the low side service fitting only. If you are not sure which fittings are which, do not attempt to recharge your air conditioner yourself. Wear eye protection and avoid direct contact with the refrigerant as it can cause frostbite on bare skin. The basic recharging procedure goes as follows: 1. Identify the low side service fitting. 2. Determine the type of refrigerant required by the system. On most 1993 and older vehicles, this would be R12. On most 1994 and newer vehicles, it would be R134a. CAUTION: R12 and R134a refrigerants are incompatible and must not be intermixed. Use the type of refrigerant required for your A/C system only. On most 1993 and newer vehicles, there's an identification decal or sticker that tells what kind of refrigerant is required. Also, the size and design of R134a and R12 service fittings are different to avoid cross-contamination. 3. Connect a can of refrigerant to a gauge set or recharging hose and valve set. Follow the equipment supplier's directions for making the connections. 4. Open the valve momentarily on the gauge set or hose to blow all air out of the line (this is necessary to keep from introducing air and moisture into your A/C system). 5. Connect the gauge set or hose to the low side A/C service ...
