2012 Subaru Forester Power Steering Fluid: What It Is, What To Use, And How To Look After It

Power-steering fluid is absolutely relevant on the 2012 Subaru Forester. This model runs a conventional hydraulic power steering system (not electric), and Subaru’s own technical literature backs that up. The 2012 Subaru Forester Owner’s Manual and the SH-chassis Subaru service manual specify automatic transmission fluid (ATF) as the power-steering fluid for this vehicle, rather than a generic “power steering fluid.”

What does the fluid actually do? In short, it transmits hydraulic assist so the steering feels light at low speeds, lubricates the pump and steering rack, carries away heat, and helps protect internal seals from wear and hardening. Fresh, correct fluid keeps the pump quiet, the steering smooth, and the rack happy over the long haul.

Fluid type matters here. Subaru specifies ATF meeting Dexron III standards (or Subaru-branded ATF) for the 2012 Forester’s power-steering system. That means don’t tip in a random “universal” power-steering fluid. Using the wrong product can lead to groans, shudder, leaks, and premature pump or rack wear. If in doubt, check the reservoir cap and the owner’s manual—both call up ATF.

Maintenance is straightforward and well worth doing. The fluid level and condition should be inspected at each routine service (every 10,000–15,000 km is a good local rule of thumb). Top-up, if needed, with the correct ATF only. While Subaru doesn’t publish a hard-and-fast replacement interval, a practical approach is to refresh the fluid every 80,000–100,000 km or about 5 years, or sooner if it looks dark, smells burnt, turns foamy, or the steering gets noisy or heavy.

• When checking the level, follow the dipstick marks (COLD/HOT) as shown in the manual.
• Have a technician inspect the pump, hoses, clamps, and rack boots for seepage.
• If flushing, use the correct ATF and bleed air by turning the wheel lock-to-lock with the front wheels lifted, engine off first, then running.
• Avoid holding the steering at full lock for more than a few seconds—that spikes pressure and heats the fluid.

Common red flags include groaning on cold start, whine when parking, a notchy or shuddery feel at low speed, foamy fluid, or a low reservoir level. Catching these early with the right ATF keeps the Forester’s steering light, quiet, and reliable.

Popular questions about 2012 Subaru Forester power-steering fluid

What fluid should go in the 2012 Forester’s power steering?
Subaru specifies ATF that meets Dexron III (or Subaru-branded ATF) for the 2012 Forester’s power-steering system. It’s not a generic power-steering fluid system—stick with ATF to avoid noise, shudder, or seal issues. The reservoir cap and the owner’s manual both call this out.

How often should the power-steering fluid be changed?
There’s no strict factory interval, but a sensible plan is to inspect every service and replace around 80,000–100,000 km or 5 years. Replace earlier if the fluid looks dark, smells burnt, turns foamy, or the steering gets noisy or heavy—especially if the vehicle tows or does lots of city parking work.

Can “power steering fluid” be used instead of ATF?
Best to avoid. The 2012 Forester is designed around ATF for its hydraulic steering. Using a generic power-steering fluid can change friction and seal behaviour, leading to whine, shudder, or leaks. If topping up or flushing, use ATF that meets Dexron III or Subaru’s own ATF.
