It is recommended, and possibly required by law, that a qualified technician perform the following services.

The air conditioning system consists of several parts to keep it functioning. The compressor, condenser, receiver drier and various hoses just to name a few. Please refer to General Information & Maintenance for information and precautions.

Some of the vehicles covered by this guide may be equipped with R-134a refrigerant systems, rather than R-12. Be ABSOLUTELY SURE what type of system you are working on before attempting to add refrigerant. Use of the wrong refrigerant or oil will cause damage to the system. Discharging, evacuating and charging the air conditioning system must be performed by a properly trained and certified mechanic in a facility equipped with refrigerant recovery/recycling equipment that meets SAE standards for the type of system to be serviced.

If you don't have access to the necessary equipment, we recommend that you take your vehicle to a reputable service station to have the work done. If you still wish to perform repairs on the vehicle, have them discharge the system, then take your vehicle home and perform the necessary work. When you are finished, return the vehicle to the station for evacuation and charging. Just be sure to cap ALL A/C system fittings immediately after opening them and keep them protected until the system is recharged.
