Parts for your 2012 Subaru Forester-Power steering pump

2012 Subaru Forester Power-Steering Pump

Yes, the 2012 Subaru Forester (SH series) uses a belt-driven hydraulic power-steering pump. This is confirmed by the Subaru Forester 2009–2013 (SH) factory service manual under Steering System – Power Steering (Hydraulic), and by Subaru’s FAST parts catalogue which lists a “Pump Complete – Power Steering” for 2012 Forester VIN ranges. Independent repair guides like the Haynes 2009–2014 Forester manual also detail pump removal, hose routing and fluid bleeding for this model, reinforcing that the vehicle is hydraulic, not electric, for power assist.

The pump’s job is simple but crucial: driven by the engine belt, it pressurises ATF to help the steering rack reduce steering effort at low speeds and deliver consistent steering feel on the move. When the pump or fluid isn’t up to scratch, drivers will notice heavy steering, groaning or whining noises on lock, or aerated/dirty fluid in the reservoir. Left too long, leaks and low fluid can cook the pump and wear out the rack seals.

As part of routine servicing on a 2012 Forester, it’s smart to check the pump, belt and hoses, and refresh the fluid periodically. Subaru specifies ATF (Dexron III/Mercon type or Subaru ATF-HP as superseded) in the power-steering system—don’t use generic “power-steering fluid”. If the fluid is dark or smells burnt, a drain-and-fill or staged flush is worth doing. After any hose or pump work, bleed by turning the wheel lock-to-lock with the engine running, topping up to keep the reservoir above MIN, and letting bubbles dissipate.

When replacement is needed (leaks at the pump shaft, noisy bearings, poor pressure), a quality reman or new pump does the trick. Plan on:

• Inspecting and, if cracked or glazed, replacing the drive belt.
• Renewing O-rings/banjo washers on pressure/return lines to prevent seepage.
• Flushing old ATF to protect the new pump and rack.
• Cleaning the reservoir screen or replacing the reservoir if contaminated.

Typical driveway time is 1.5–3 hours with basic spanners and a drain pan, a hoist makes it tidier. In Australia and New Zealand, budgeting for a pump, fresh ATF and sundries is common-sense—add more if hoses or the rack show their age. Keep an ear out for new noises after the job, recheck fluid after the first few hundred kilometres, and you’ll keep the Forester’s steering light, quiet and confidence-inspiring.

Popular questions about 2012 Subaru Forester power-steering pumps

Does the 2012 Forester have electric or hydraulic power steering?
It’s hydraulic. The 2012 SH Forester runs a belt-driven pump feeding the steering rack. Electric power steering arrived with the next-generation SJ Forester (from 2014) in most markets.

What fluid should be used in the power-steering system?
Use automatic transmission fluid that meets Dexron III/Mercon specs (or Subaru ATF-HP where specified). Avoid universal “power-steering fluid”. Mixing types can cause noise and seal issues, so stick to one quality ATF and flush if you’re changing type.

How much does a pump replacement cost and how long does it take?
Expect 1.5–3 hours of labour, depending on access and seized fasteners. Parts pricing varies by brand, many owners go for a reputable reman pump plus fresh ATF and new sealing washers. Add extra if hoses or the reservoir need replacing.
