Parts for your 2012 Subaru Impreza-Power steering hose

2012 Subaru Impreza power-steering hose — do you actually have one?

For the 2012 Subaru Impreza hatch and sedan on the GP/GJ platform (the regular 2.0-litre models sold in Australia and New Zealand), a power‑steering hose isn’t fitted or required. These cars use an electric power steering (EPS) system, so there’s no hydraulic pump, no reservoir, and no pressure/return hoses to leak or replace.

Technical sources that back this up:

• Subaru Service Manual, Impreza GP/GJ (2012): Steering section identifies an Electric Power Steering system with a column/rack‑mounted electric motor and control module, not a hydraulic circuit.
• Subaru Global/Regional Parts Catalogue (FAST) for GP/GJ: lists no hydraulic power‑steering pump, lines or hoses for 2012 Impreza 2.0i variants, hydraulic hoses only appear under WRX/WRX STI for the same model year.
• 2012 Impreza Owner’s Manual/Specifications: no power‑steering fluid is listed under service capacities because EPS doesn’t use fluid.

Why no hose? EPS delivers steering assist via an electric motor and reduction gear, taking its cues from a torque sensor and a control unit. Without a hydraulic pump and lines, there’s nothing to bleed, no fluid to flush, and no rubber hoses to perish. The upside is fewer leaks, a tidier engine bay, better fuel economy (no belt‑driven pump), and more consistent steering feel at different speeds.

Worth noting: the 2012 WRX and WRX STI are a different kettle of fish. They carried over a hydraulic power‑steering setup in that era and do have power‑steering hoses. If you’re in a WRX/STI, hose condition, clamp integrity and pump weeping are valid checks during servicing. For non‑WRX 2012 Impreza owners, if someone’s recommending a “power‑steering fluid flush”, that doesn’t apply to your EPS car.

Good practice on an EPS‑equipped 2012 Impreza:

• Keep the battery and charging system healthy — low voltage can upset EPS assist.
• Inspect rack boots and tie‑rod ends for splits or play, and listen for any EPS warning lights or unusual steering noises.
• If you notice fluid under the front end, it’ll be from something else (engine oil, transmission, coolant, or a CV boot), not power‑steering fluid.
• After suspension work or kerb strikes, get an alignment — EPS still relies on sound geometry and tyres for feel and safety.

Bottom line: for the 2012 Impreza GP/GJ, a “power‑steering hose” isn’t relevant because the car doesn’t use one. That’s one less service item to worry about.

Popular questions

Does a 2012 Subaru Impreza have power‑steering fluid or hoses?
For the standard 2012 Impreza (GP/GJ), no. It runs electric power steering, so there’s no fluid, pump, or hoses. If you own a 2012 WRX/STI, that’s different — those models kept a hydraulic system and do have hoses.

How can I tell if my 2012 Impreza is EPS or hydraulic?
Open the bonnet: if there’s no power‑steering fluid reservoir or pump on the accessory belt, it’s EPS. The GP/GJ VIN and build plate will also identify the platform, the WRX/STI of the same year uses the earlier platform with a hydraulic setup.

I’ve got a 2012 WRX — do I need to service the power‑steering hoses?
Yes. Check for seepage at the pressure hose crimps, softness or cracking in the return hose, and fluid level/colour. Replace hoses that are swollen, cracked, or leaking, and use the correct fluid specified by Subaru.
