CAUTION

  1. Wear working clothing, including a cap, protective goggles, and protective shoes during operation.
  2. Remove contamination including dirt and corrosion before removal, installation or disassembly.
  3. Keep the disassembled parts in order and protect them from dust or dirt.
  4. Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary removal, installation, disassembly, and replacement.
  5. Be careful not to burn your hands, because each part in the vehicle is hot after running.
  6. Be sure to tighten fasteners including bolts and nuts to the specified torque.
  7. Place shop jacks or safety stands at the specified points.
  8. Before disconnecting electrical connectors of sensors or units, be sure to disconnect negative terminal from battery.

RELATIONSHIP OF SUBARU COOLANT CONCENTRATION & FREEZING TEMPERATURE

The concentration and safe operating temperature of the SUBARU coolant is shown in the diagram. Measuring the temperature and specific gravity of the coolant will provide this information.

[ Example ]

If the coolant temperature is 25°C (77°F) and its specific gravity is 1.054, the concentration is 35% (point A), the safe operating temperature is -14°C (7°F) (point B), and the freezing temperature is -20°C (-4°F) (point C).
