2007 Subaru Forester Power Steering Fluid — What It Does and How to Look After It

Power-steering fluid is absolutely relevant to the 2007 Subaru Forester. Technical sources including the 2007 Subaru Forester Owner’s Manual (power steering section) specify using Automatic Transmission Fluid (ATF) meeting Dexron III for the power steering reservoir, and the Subaru Workshop/Service Manual for the SG-series Forester shows a belt-driven hydraulic pump and hydraulic steering rack. That confirms this model doesn’t have electric power steering, it relies on hydraulic fluid to do the heavy lifting.

On a 2007 Forester, power-steering fluid acts as the lifeblood of the hydraulic assist system. The engine-driven pump pressurises the ATF, which then helps the steering rack move with much less effort, especially at low speeds or when parking. The fluid also carries away heat and lubricates internal parts, keeping the pump, valves and rack seals happy. When the fluid is old, contaminated, or low, drivers may notice heavier steering, whining or groaning on turns, foamy fluid in the reservoir, or red oily spots under the front of the car.

Subaru calls for ATF (Dexron III spec) in the power-steering system on this year of Forester. A quality Dexron III-compatible ATF or Genuine Subaru ATF is the go, avoid generic “power-steering-only” fluids unless they explicitly state Dexron III compatibility. During regular servicing, it’s smart to check level and colour with the engine warm, after cycling the steering lock-to-lock a couple of times. Top up only to the HOT mark on the reservoir and don’t overfill.

While many owner’s manuals don’t set a strict change interval, a preventative refresh every 60,000–100,000 km (or around 3–5 years) keeps the system quiet and the seals in good nick—earlier if the fluid turns dark, smells burnt, or there’s any noise. A full flush is best done professionally to avoid aeration, but a staged “turkey baster” exchange between services also helps.

• Use Dexron III-spec ATF for the 2007 Forester’s power-steering system.
• Inspect level and colour at each service, address leaks at hoses, pump, or rack promptly.
• If the steering whines or feels heavy, don’t ignore it—fresh fluid and leak fixes can save the pump and rack.

Popular questions

What fluid type should a 2007 Subaru Forester use for power steering?
It’s designed for ATF that meets Dexron III specifications. Many owners choose Genuine Subaru ATF or a reputable Dexron III-compatible fluid. Avoid non-ATF power-steering fluids unless they clearly state Dexron III compatibility.

How often should the power-steering fluid be changed on a 2007 Forester?
Check it at every service. If it’s dark, smells burnt, or the steering is noisy, change it. As a preventative measure, many workshops recommend refreshing the fluid every 60,000–100,000 km or about 3–5 years, depending on use and climate.

What are the signs of low or failing power-steering fluid?
Common signs include a whining or groaning noise while turning, heavier-than-normal steering, foamy fluid in the reservoir, and red ATF drips near the front crossmember. Sorting the fluid and any leaks early can prevent pump or rack damage.
