3. Tools and Equipment
The following section provides information about the tools
and equipment that will be necessary to properly service
the A/C system.
Since equipment may vary slightly depending on the
manufacturer, it is important to always read and follow the
manufacturer’s instructions.
CAUTION:
When working on vehicles with the HFC-134a system,
only use HFC-134a specified tools and parts. Do not
mix with CFC-12 tools and parts. If HFC-134a and
CFC-12 refrigerant or compressor oil is mixed, poor
lubrication will result and the compressor itself may be
destroyed.
In order to help prevent mixing HFC-134a and CFC-12
parts and liquid, the tool and screw type and the type
of service valves used are different. The gas leak
detectors for the HFC-134a and CFC-12 systems must
also not be interchanged.

Valve type Quick joint type Screw-in type
Tools and Equipment Description
WRENCH
VariousWRENCHESwill be required to service any A/C
system. A 7 to 40 N⋅m (0.7 to 4.1 kg-m, 5 to 30 ft-lb) torque
wrench with various crowfoot wrenches will be needed. Open
end or flare nut wrenches will be needed for back-up on the
tube and hose fittings.

APPLICATOR BOTTLE
A smallAPPLICATOR BOTTLEis recommended to apply
refrigerant oil to the various parts. They can be obtained at a
hardware or drug store.
