AUTOMATIC AIR CONDITIONING SYSTEM IW3ool 4-7
3. Tools and Equipment
The following section provides information about the tools
and equipment that will be necessary to properly service the
air conditioning system .
Since equipment may vary slightly depending on the
manufacturer, it is important to always read and follow the
manufacturer's instructions .
In order to help prevent mixing R134a and R12 parts and
liquid, the tool and screw type and the type of service
valves used are different. The gas leak detectors for the
R134a and R12 systems must also not be interchanged .

Valve type i
Quick joint type
Screw-in type
When working on vehicles with the R134a system, only
use R134a specified tools and parts. Do not mix with R12
tools and parts. If R134a and R12 refrigerant or compres-
sor oil is mixed, poor lubrication will result and the com-
pressor itself may be destroyed.
