Section 159 (Manual HVAC System): General Description: Preparation Tool
WARNING: This page is about a different car, the 2003 Subaru Outback, 2003 Subaru Legacy, and 2003 Subaru Baja. However, it is still accessible from the selected car via links, so may be relevant.
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.
