Quick answer
The 2020 Subaru Outback holds between 7.6 and 8.9 quarts (7.2 and 8.4 liters) of coolant, depending on the engine option.
- Total cooling system capacity: 7.6–8.9 quarts (7.2–8.4 liters)
- OEM coolant specification: Subaru Super Coolant (Blue, P-OAT)
- Mix ratio: 50/50 with distilled water (pre-mix is recommended)
Capacity by engine option
| Engine | Capacity (quarts) | Capacity (liters) |
|---|---|---|
| 2.5L H4 | 7.6 | 7.2 |
| 2.4L Turbo H4 | 8.9 | 8.4 |
Flush interval
Subaru recommends an initial coolant flush at 11 years or 137,500 miles. After the initial service, the interval is every 6 years or 75,000 miles, whichever comes first.
How to refill & bleed
- Ensure the engine is cool.
- Slowly add a 50/50 mix of Subaru Super Coolant and distilled water to the radiator and reservoir tank.
- Start the engine and let it warm up with the heater on high. This circulates the coolant.
- As the engine warms, the coolant level may drop. Continue to top it off until it stabilizes.
- Check for leaks. No special bleeding procedure is required for this vehicle.
Common cooling system issues
