Parts for your 2013 Subaru Impreza-Power steering pump

2013 Subaru Impreza power-steering-pump — not fitted, and here’s why

For the 2013 Subaru Impreza (non-WRX models, chassis codes GP/GJ), a traditional hydraulic power-steering pump isn’t fitted. Technical documentation confirms the car uses an electric power-assisted steering (EPS) system. The Subaru Service Manual for the 2012–2016 Impreza steering section identifies a column-type electric motor providing assist rather than a belt-driven hydraulic pump, lines and fluid. The 2013 Owner’s Manual likewise describes electric power steering and does not list any power-steering fluid checks, and Subaru’s model literature for this generation calls it “electric power-assisted steering”.

Because assist is provided by an electric motor and control module, there’s no hydraulic pump to drive off the engine and no power-steering fluid circuit. Subaru engineered EPS into this generation to reduce parasitic losses, trim fuel consumption, and simplify servicing. It also allows smarter tuning of steering effort at different speeds and reduces the number of wear items under the bonnet. Note: the 2013 WRX/WRX STI (a different platform to the GP/GJ Impreza) retained a hydraulic system with a pump, but that doesn’t apply to the standard 2013 Impreza range.

What does this mean for owners? There’s no power-steering-pump service on the 2013 Impreza, and no fluid to top up or leak checks for hoses. Steering care shifts toward electrical and mechanical checks that keep EPS happy and the steering feel consistent.

• Battery and charging health: EPS draws on the 12V system. A weak battery or alternator can cause heavy steering or a warning lamp.
• Steering column and rack checks: Listen and feel for play, noise or notchiness, inspect intermediate shaft joints and rack boots during routine servicing.
• Wheel/tyre and alignment: Correct pressures, good tyres and a proper alignment dramatically affect steering feel and effort.
• Diagnostics if the EPS light appears: Scan for steering-related fault codes, verify fuses and connectors, and perform steering angle sensor calibration if required.

If you’ve been hunting for a “2013 Subaru Impreza power-steering-pump”, the short answer is it’s not there—by design, according to Subaru’s own service and owner information. Focus maintenance on the EPS-related checks above and you’ll be sorted.

Popular questions

Does a 2013 Subaru Impreza have a power-steering pump?
No. The standard 2013 Impreza (GP/GJ) uses electric power-assisted steering, so there’s no hydraulic pump or fluid. That’s documented in Subaru’s service and owner manuals for this generation. Only the separate 2013 WRX/WRX STI models (older platform) used a hydraulic pump.

What maintenance replaces power-steering fluid changes on a 2013 Impreza?
There’s no fluid service. Prioritise battery and alternator health, inspect the steering column joints and rack boots, keep tyres correctly inflated, and ensure wheel alignment is on spec. If an EPS light comes on or the steering feels heavy, have the system scanned for fault codes and the steering angle sensor checked.

My steering feels heavy at low speeds—what should I check?
Start with the basics: battery condition, alternator output, and all related fuses. Then check tyre pressures and look for any binding in the column joints. A scan for EPS fault codes will point to issues such as a failing torque sensor or control module concern.
