The 2015 Subaru Forester typically holds around 7.9 to 8.2 quarts (7.5 to 7.8 liters) of coolant, depending on the engine and transmission. This article will provide a comprehensive guide to your Forester's coolant system.
Quick Answer
- Total Cooling System Capacity: Approximately 7.9 - 8.2 quarts (7.5 - 7.8 liters)
- OEM Coolant Spec: Subaru Super Coolant (Blue, Long-Life Hybrid Organic Acid Technology - HOAT/Si-OAT)
- Mix Ratio: 50/50 Pre-mixed (or mix concentrate with distilled water)
Capacity by Engine Option
The 2015 Subaru Forester came with two engine options, and the coolant capacity can vary slightly.
| Engine Type | Capacity (Quarts) | Capacity (Liters) |
|---|---|---|
| 2.5L DOHC (FB25) | 7.9 - 8.2 | 7.5 - 7.8 |
| 2.0L DOHC Turbo (FA20) | 7.9 - 8.2 | 7.5 - 7.8 |
Note: These figures are approximate and may vary slightly based on residual old coolant remaining after a drain. For definitive capacity, always refer to your owner's manual.
