R-134A Refrigerant

R-134a REFRIGERANT

This vehicle uses a refrigerant called R-134a. It is a non-toxic, non-flammable, clear colorless liquefied gas.

R-134a refrigerant is not compatible with R-12 refrigerant in an air conditioning system. Even a small amount of R-12 in a R-134a system could cause compressor failure, refrigerant oil to sludge and/or poor performance. Never add any other type of refrigerant to a system designed to use R-134a refrigerant. System failure will occur.

The high pressure service port is located on the filter/drier. The low pressure service port is located on the suction line near the strut tower.

Refrigerant Recovery/Recycling Station - Typical:




When servicing a system, it is required that an air conditioning charging recovery/recycling machine be used. Contact an automotive service equipment supplier for proper equipment. Refer to the operating instructions provided with the equipment for proper operation.

Manifold Gauge Set - Typical:




A manifold gauge set must also be used in conjunction with the charging and/or recovery/recycling device. Only use gauges that have not been used for R-12. The service hoses on the gauge set should have manual (turn wheel) or automatic back flow valves at the service port connector ends. This will prevent refrigerant R-134a from being released into the atmosphere.

R-134a refrigerant requires a special type of compressor oil. When adding oil, make sure to use the oil that is specified on the under hood label.

The use of R-134a will have a positive environmental impact due to it's zero ozone depletion and low global warming impact.
