Subaru WRX Fluid Capacities
All fluid capacities for your Subaru WRX: engine oil, coolant, transmission fluid, brake fluid, power steering, and more.
Quick Answer
The Subaru WRX requires multiple fluids maintained at specific levels. Engine oil, coolant, transmission fluid, brake fluid, and power steering fluid all have different capacities depending on your engine and model year.
2019-2024
2019-2024Engine OilVaries by engine — check owner's manual (typically 4-8+ quarts)
Coolant (total system)6.0 - 10.0 quarts
Transmission Fluid3.5 - 4.0 quarts (drain & fill) / 7-9 quarts (total)
Brake FluidDOT 3 or DOT 4 — ~1 quart for full flush
Power Steering FluidElectric power steering — no fluid needed
Windshield Washer~1 gallon
Notes
- →Never mix different types of coolant — flush completely when changing brands
- →Many newer models use electric power steering — no power steering fluid required
- →Transmission fluid should be checked with the engine running and at operating temperature
- →Brake fluid absorbs moisture over time — replace every 2-3 years regardless of mileage

Frequently Asked Questions
- How much coolant does a Subaru WRX hold?
- The Subaru WRX cooling system holds 6-10 quarts total depending on the engine. A drain-and-fill replaces about 50-60% of the coolant. For a complete flush, you'll need the full capacity amount.
- What type of transmission fluid does a Subaru WRX use?
- The Subaru WRX transmission fluid type depends on whether it's an automatic or manual transmission and the model year. Always use the manufacturer-specified fluid — check your owner's manual for the exact ATF or manual transmission fluid required.
- Does a Subaru WRX have power steering fluid?
- 2015+ Subaru WRX models with electric power steering don't use power steering fluid. Older models with hydraulic power steering use ATF or manufacturer-specific fluid — check your owner's manual.
- What brake fluid does a Subaru WRX use?
- Most Subaru WRX models use DOT 3 or DOT 4 brake fluid. DOT 4 has a higher boiling point and is preferred for performance driving. Never use DOT 5 (silicone-based) in a system designed for DOT 3/4.
