HVAC SYSTEM (HEATER, VENTILATOR AND A/C) > General Description
1. SPECIAL TOOL
SUBARU SELECT MONITOR III KIT
Used for troubleshooting the electrical system.
For detailed operation procedures of SUBARU SELECT MONITOR III KIT, refer to “PC application help for Subaru Select Monitor”.
SPECIAL TOOL CONDENSER
Used for installing the condenser.
2. GENERAL TOOL
When working on vehicles with a HFC-134a system, only use HFC-134a specified tools and parts. Do not mix CFC-12 tools and parts. If HFC-134a and CFC-12 refrigerant or compressor oil is mixed, it will result in poor lubrication and the compressor itself may be damaged.
In order to prevent the mixture of HFC-134a and CFC-12 parts and liquid, the type of tool and screw, and the replacement valves used are different. The gas leak detectors for the HFC-134a and CFC-12 systems must also not be interchanged.
Tool & screw type
Quick joint type
Tools and Equipment
Various WRENCHES will be required to service any A/C system.7 — 40 N·m (0.7 to 4.1 kgf-m, 5 to 30 ft-lb) torque wrench and various crowfoot wrenches will be needed. Open end or flare nut wrenches will be needed to affix the pipe and hose fittings.
A small APPLICATOR BOTTLE is recommended to apply compressor oil to the various parts. It can be available at a hardware store.

Refrigerant recovery system
A REFRIGERANT RECOVERY SYSTEM is used for the recovery and recycling of A/C system refrigerant after contaminants and moisture have been removed from the refrigerant.
A graduated plastic SYRINGE will be needed to add oil into the system again. A syringe can be available at a pharmacy or drug store.
A VACUUM PUMP is necessary (for a good working condition), and may be available at either a refrigerant supplier or an automotive equipment supplier.
A CAN TAP for the 397 g (14 oz.) can is available at an automotive equipment supplier.
A Pocket THERMOMETER is available at either a industrial hardware store or a refrigerant supplier.
Electronic leak detector
An ELECTRONIC LEAK DETECTOR can be available at either a specialty tool supplier or an A/C equipment supplier.
