Parts for your 2020 Subaru Impreza-Power steering pump

2020 Subaru Impreza power-steering-pump — what’s fitted and what’s not

Short answer: a traditional hydraulic power-steering pump isn’t used on the 2020 Subaru Impreza. Technical sources including the 2020 Subaru Impreza Owner’s Manual (Steering section) and the Subaru Service Manual via Subaru’s Technical Information System identify an Electric Power-Assisted Steering (EPS) setup. That documentation details an electric motor and control unit on the steering assembly rather than a belt-driven hydraulic pump, reservoir and hoses. Genuine parts catalogues for MY20 Impreza likewise list no power-steering pump or fluid circuit, reinforcing that there’s nothing to replace or top up.

Why no pump? Subaru shifted the fifth‑gen Impreza (on the Subaru Global Platform) to EPS to reduce parasitic losses on the engine, cut weight, and improve fuel efficiency. An electric motor only draws power when assist is needed, which helps with economy around town and on the open road. EPS also integrates neatly with driver‑assist features and calibration strategies, letting engineers tune steering feel and lane‑support functions more precisely than a hydraulic system could manage.

So, there’s no power-steering fluid to buy, no belt to squeal, and no pump to leak under the bonnet. That said, the steering still appreciates sensible care during regular servicing.

• Keep the battery and charging system in good nick — low voltage can make EPS feel heavy or inconsistent.
• Have the wheel alignment checked and tyres rotated, poor alignment feels like steering trouble.
• Inspect rack boots and column joints for wear or damage.
• If the steering warning light pops up, ask for a scan with Subaru’s diagnostic tool (e.g., SSM) to check the EPS control unit and torque sensor calibration.
• When jump‑starting, follow correct procedure to avoid voltage spikes that can upset EPS electronics.

For anyone searching “2020 Subaru Impreza power-steering-pump”, the practical takeaway is simple: there isn’t one. The car uses electric assist, which trims routine maintenance and eliminates the usual hydraulic leaks and pump whine. If the steering ever feels off, start with electrical health and alignment rather than hunting for a non‑existent reservoir.

Popular questions

Does the 2020 Subaru Impreza have a power-steering pump?
No. It uses Electric Power-Assisted Steering, so there’s no hydraulic pump, belt, hoses, or fluid to service.

What power‑steering fluid does a 2020 Impreza take?
None. Because the steering is electric, there’s no hydraulic fluid to top up. Any fluid tanks you see under the bonnet are for other systems (brakes, coolant, washers).

How is steering maintenance handled without a pump?
Focus on electrical and mechanical basics: battery and alternator health, alignment and tyre condition, intact rack boots and column joints, and diagnostic scans if the EPS warning appears.
