1. Keep the engine running at idling speed.

2. Open the engine hood to ventilate the engine compartment. Refer to “Engine hood”.

Confirm that the cooling fan is turning. If the fan is not turning, immediately turn off the engine and contact an authorized SUBARU dealer for repair.

3. After the coolant temperature high warning light that has blinked or illuminated in RED turns off, turn off the engine.

For details about the warning light, refer to “Coolant temperature low indicator light/ Coolant temperature high warning light”.

4. After the engine has fully cooled down, check the coolant level in the reserve tank. If the coolant level is below the “LOW” mark, add coolant up to the “FULL” mark.

NOTE
For details about how to check the coolant level or how to add coolant, refer to “Engine coolant”

5. If there is no coolant in the reserve tank, add coolant to the reserve tank.

Then remove the radiator cap and fill the radiator with coolant.

If you remove the radiator cap from a hot radiator, first wrap a thick cloth around the radiator cap, then turn the cap counterclockwise slowly without pressing down until it stops. Release the pressure from the radiator. After the pressure has been fully released, remove the cap by pressing down and turning it.
