1. HEATER SYSTEM

Subaru Outback. HVAC System (Heater, Ventilator and A/C)

2. A/C SYSTEM

Subaru Outback. HVAC System (Heater, Ventilator and A/C)

3. BASIC OPERATION

The cooling system cools down the compartment by using the pipes connecting parts and cycling the evaporable liquid (refrigerant) within the sealed system in a repeated process of "vaporization - liquefaction - re-vaporization".

1. SPECIAL TOOL

Subaru Outback. HVAC System (Heater, Ventilator and A/C)

2. GENERAL TOOL

CAUTION: 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.
