If the coolant level drops within a short time after replenishing
Visually check the radiator, hoses, engine coolant filler cap, radiator cap,
drain cock and water pump.
If you cannot find a leak, we recommend that you have any authorized
SUBARU dealer or repairer, or another duly qualified and equipped profes-
sional pressure test the cap and check for leaks in the cooling system.
■
Coolant selection
Only use SUBARU Super Coolant or similar high-quality ethylene glycol-
based non-silicate, non-amine, non-nitrite, and non-borate coolant with long-
life hybrid organic acid technology.
SUBARU Super Coolant is a mixture of 50% coolant and 50% deionized
water. (Enabled: -35

For more details about engine coolant, we recommend that you contact any
authorized SUBARU dealer or repairer, or another duly qualified and
equipped professional.
WARNING
■
When the engine is hot
Do not remove the radiator cap.
The cooling system may be under pressure and may spray hot coolant if the
cap is removed, causing serious injuries, such as burns.
CAUTION
■
When adding engine coolant
Coolant is neither plain water nor straight antifreeze. The correct mixture of
water and antifreeze must be used to provide proper lubrication, corrosion
protection and cooling. Be sure to read the antifreeze or coolant label.
■
If you spill coolant
Be sure to wash it off with water to prevent it damaging parts or paint.
