What color is Subaru power steering fluid?
Subaru power steering fluid is typically red.
In most Subaru models, the steering system uses automatic transmission fluid (ATF) dyed red; the color can range from bright red to pink, and it can darken with age or contamination. The exact shade is less important than using the fluid specified for your vehicle and keeping it clean and at the proper level.
Color and compatibility
Color alone is not a reliable indicator of suitability. Always rely on the owner’s manual or the official Subaru service guidelines to confirm the approved fluid type for your specific model and year. The reservoir may be labeled, and the fluid should resemble the typical red hue of ATF, rather than clear or brownish without reason.
For most Subarus, the recommended fluid is a type of automatic transmission fluid that meets the vehicle’s Dexron II/III specifications or an equivalent specification. The dye in ATF gives it a red appearance, but the exact shade can vary depending on the batch and age of the fluid.
Model-year variations
Older Subaru models
Older Subarus commonly used ATF Dexron II or Dexron III for the power steering system. The fluid is dyed red, but it can darken with heat and time. If you’re servicing an older model, verify the specific Dexron specification required in the owner’s manual and avoid mixing fluids from different specifications.
Newer Subaru models
newer Subaru vehicles may still use ATF-based power steering fluid, with many models compatible with Dexron II/III or Dexron VI or equivalent fluids. The color remains red due to the dye, but always check the latest Subaru maintenance guidelines for your exact model year and transmission type.
Practical maintenance tips
Before adding or replacing fluid, identify the correct specification for your model. Do not use brake fluid, engine oil, or other substitutes in the power steering reservoir, and avoid mixing different ATF types unless the manual explicitly allows it. If the fluid looks unusually dark, has a burnt odor, or you notice steering effort changes, consider a fluid change or system inspection at an authorized service center.
To maintain color and performance, check the fluid level regularly and top up with the recommended ATF only. If you’re uncertain about the correct fluid type or the color seems inconsistent with expectations for your model year, consult a Subaru dealer or certified mechanic for verification.
Summary
Subaru power steering fluid is generally red, a result of the automatic transmission fluid used in the system. The exact shade can vary with age, heat, and contamination. Always follow the owner’s manual for the correct fluid specification, avoid mixing different fluids, and seek professional advice if the fluid color or steering behavior seems out of the ordinary.
