Chevrolet Captiva Service & Repair Manual: Refrigerant Filter, Replace
| Caution: Air conditioning R-134a
liquid refrigerant is capable of harming eyes or freezing skin. Always wear
safety goggles and avoid contact with liquid refrigerant. Failure to follow
these instructions may result in serious personal injury. |
| Caution: Air conditioning R-134a
refrigerant gas is capable of displacing the air required for breathing
in a confined space and can produce toxic gasses if burned at high temperatures.
Do not release a large quantity of R-134a gas within a confined space or
allow it to be exposed to a high temperature flame (such as a torch). Consult
the Material Safety Data Sheet for further information. Failure to follow
these instructions may result in serious personal injury or death. |
| Caution: Use extreme care and
observe all safety and service precautions related to the use of refrigerants
as outlined on refrigerant tank and on recovery and charging equipment.
Failure to follow these instructions may result in serious personal injury. |
| Your vehicles air conditioning
system relies on A/C compressor oil to be circulated throughout the system
and maintain compressor lubrication. In fact, the A/C compressor and the
seals are the only reason for A/C oil. There are no other components that
require lubrication, and on orifice tube systems, the A/C compressor is
the only moving component. |
| When the air conditioning system
starts to get contaminated, harmful acids are formed. Those acids cause
corrosion and debris. That corrosion easily can restrict an orifice tube
or expansion valve. When that happens, the flow of oil to your compressor
stops. |
Removal
| 1. |
Recover air conditioning refrigerant
with a suitable air conditioning station. |
