NOTE:
When adding the engine coolant, always use SUBARU Super Coolant.
- Park the vehicle on a level surface.
- Check the engine coolant amount, and if the coolant level is low, check for the coolant leakage, and then add the engine coolant.
- Make sure the engine coolant level in the reservoir tank is between "FULL" and "LOW" with the engine in a cold condition.
- Open the radiator cap and make sure that the radiator is filled with the engine coolant up to its filler neck position.
