Subaru Super Coolant Blue 1 Gallon Prediluted 50/50 OEM Antifreeze – Corrosion Protection, -62°F Freeze Guard

Subaru Genuine Super Coolant Blue is a factory-formulated, 50/50 pre-mixed coolant that protects Subaru cooling systems from corrosion and cold-weather damage right out of the gallon.

This OEM coolant comes premixed to Subaru’s specifications so you can top off or refill the cooling system without worrying about water quality or improper dilution. The blue formula SOA868V9272 replaces the older SOA868V9270 and is engineered for Subaru models from 2009 and newer, including Ascent, BRZ, Crosstrek, Forester, Impreza, Legacy, Outback and WRX. It contains organic corrosion inhibitors and a bittering agent to discourage ingestion, and offers freeze protection down to -62°F when used as directed.

Why should I choose a Subaru-branded pre-mixed coolant?

Using an OEM coolant helps ensure chemical compatibility with Subaru radiators, hoses, gaskets and aluminum components. The prediluted 50/50 mix removes the guesswork of measuring and using tap water, which can introduce minerals that accelerate wear.

• Factory-formulated to Subaru specifications for material compatibility.
• Ready-to-use 50/50 mix saves time and avoids dilution errors.
• Organic corrosion inhibitors extend protection across the cooling system.
• Bittering agent added for safety to deter accidental ingestion.

How does this coolant protect my engine in cold weather?

The Subaru Super Coolant Blue provides freeze protection to -62°F at the recommended 50/50 concentration, preventing coolant from freezing in radiators and hoses. Keeping the coolant within specification also helps maintain heater performance and prevents blockages from ice formation in extreme temperatures.

• Freeze protection rated to -62°F at 50/50 concentration.
• Maintains flow through radiator and heater core in cold climates.
• Helps avoid freeze-related pressure spikes and coolant system damage.

Will this coolant prevent rust and corrosion in my vehicle?

Yes — the formula uses organic corrosion inhibitors specifically selected to protect aluminum, cast iron and other metals commonly found in Subaru cooling systems. Regular use and proper coolant concentration help form a protective barrier that reduces electrochemical corrosion and extends component life.

• Organic inhibitors protect aluminum radiators and engine passages.
• Reduces rust formation and metal pitting in the cooling circuit.
• Designed for long-lasting performance when maintained to schedule.

How do I use this 1-gallon prediluted coolant safely and correctly?

Because it’s a 50/50 premix, you can pour directly into the coolant reservoir or radiator after the engine is cool. Follow Subaru’s service recommendations for fluid capacity, system flushing intervals and disposal of old coolant; always avoid mixing with incompatible coolants of different chemistries.

• Pour directly—no additional water required at 50/50 concentration.
• Top off or refill when the engine is cool; adhere to capacity specs.
• Do not mix with nitrate- or silicate-based coolants to avoid compatibility issues.

Who is this for? Subaru owners and technicians who want a reliable, OEM-specified coolant that’s ready to use right away. It’s ideal for drivers in cold climates, shop owners doing service on 2009-and-newer Subaru models, and anyone who prefers the assurance of a factory-approved fluid instead of aftermarket alternatives. Use it when replacing or topping off coolant to maintain warranty alignment and ensure proper protection for Subaru cooling systems.
