Grand Voyager V6-3.8L VIN L (1999)
Refrigerant: Description and Operation
This vehicle uses a new type of 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 liquid line near the strut tower. The low pressure service port is located on the suction line near the
compressor manifold.
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.
Due to the different characteristics of R-134a it requires all new service procedures.
The use of R-134a will have a positive environmental impact due to it's zero ozone depletion and low global warming impact.
