2022 Subaru Crosstrek — Coolant Capacity & Type

The 2022 Subaru Crosstrek with the 2.0L engine holds approximately 7.2 quarts (6.8 liters) of coolant, while models equipped with the 2.5L engine hold approximately 8.0 quarts (7.6 liters).

Quick answer

• Total Cooling System Capacity: 2.0L engine: ~7.2 quarts (6.8 liters), 2.5L engine: ~8.0 quarts (7.6 liters)
• OEM Coolant Spec: Subaru Super Coolant (Blue, HOAT, extended-life, ethylene glycol-based). It meets Subaru's stringent material compatibility and corrosion protection standards.
• Mix Ratio: Typically sold as a 50/50 pre-mix. If using concentrate, mix with distilled water to a 50/50 ratio.

Capacity by engine option

Flush interval

Subaru recommends inspecting the coolant level and condition at every service interval. The factory-fill Subaru Super Coolant is a long-life formulation with an extended service interval:

• Normal Duty: Replace at 137,500 miles or 11 years, whichever comes first. After the initial replacement, subsequent replacements are recommended every 75,000 miles or 6 years.
• Severe Duty: While Subaru doesn't explicitly define a "severe duty" coolant interval, if your vehicle experiences frequent towing, extensive off-road use, or operates in extreme climates, it's wise to consider shortening the replacement interval to around 75,000 miles or 6 years.

How to refill & bleed

Refilling and bleeding the cooling system on your 2022 Subaru Crosstrek is crucial to prevent air pockets that can cause overheating. Always perform this on a cool engine.

1. Drain: With the engine cool, place a drain pan under the radiator. Open the radiator drain cock (usually on the bottom of the radiator). Remove the radiator cap to allow for faster draining. For a complete flush, you may want to drain the engine block as well, though this can be more involved.
2. Close Drain & Refill: Close the radiator drain cock. Slowly add the correct type and mix of Subaru Super Coolant into the radiator filler neck. Fill until it reaches the top.
3. Fill Reservoir: Fill the coolant overflow reservoir to the "FULL" mark.
4. Bleeding (Crucial Step): This is where it
