Parts for your 2018 Subaru Forester-Power steering pump

2018 Subaru Forester power‑steering pump: what’s fitted and what’s not

For the 2018 Subaru Forester (SJ series), a traditional hydraulic power‑steering pump isn’t fitted. Subaru’s technical literature for the SJ Forester—namely the Subaru Service Manual steering section (Power Assist System – Electric Power Steering), the 2018 Owner’s Manual, and Subaru’s New Car Features documentation—specifies an Electric Power Steering (EPS) system. Those documents describe an electric motor and control module providing steering assist, with no hydraulic pump, drive belt, hoses or power‑steering fluid reservoir listed for this model year.

Why no pump? Because EPS does the job. The 2018 Forester’s EPS uses an electric motor and torque sensor managed by an ECU to add steering assist. That hardware removes the need for a belt‑driven hydraulic pump entirely, which trims parasitic load on the engine and helps fuel economy. With fewer moving parts and no fluid circuit, it also sidesteps common pump‑related issues like leaks, noise and periodic fluid changes.

Owners still get the benefits they expect: speed‑sensitive assist, a tidy steering feel around town, and confident weighting on the open road—all without the maintenance a hydraulic pump would bring. Instead of pump or fluid servicing, routine care focuses on the steering rack, joints and the vehicle’s electrical health (since EPS relies on clean battery voltage and charging performance).

• No power‑steering fluid to top up or flush—there isn’t any on the 2018 Forester.
• Keep the 12‑volt battery and charging system in good nick, weak voltage can reduce assist.
• During regular servicing, inspect inner/outer tie‑rods, rack boots and front suspension for wear.
• If the EPS warning lamp appears or the wheel feels unexpectedly heavy, have faults scanned and connectors to the EPS module/torque sensor checked by a licensed tech.

So, if someone’s quoting a “power‑steering pump replacement” for a 2018 Forester, they’re looking at the wrong model or the wrong part. The steering assist system on this year Forester is electric, not hydraulic—no pump required.

• Does the 2018 Subaru Forester have a power‑steering pump?
  It doesn’t. This model runs Electric Power Steering, so there’s no hydraulic pump, belt or fluid. If you’re chasing a steering issue, think electrical supply, EPS fault codes or steering rack components—not a pump.
• What steering maintenance does a 2018 Forester need?
  No fluid flushes. Keep the battery healthy, confirm alternator output, and at service time check tie‑rod ends, rack boots and alignment. If an EPS light or heavy steering crops up, get it scanned with Subaru‑capable diagnostics.
• What are signs of EPS trouble on a 2018 Forester?
  Heavier‑than‑normal steering, an EPS warning lamp, or assist that cuts in and out at low speeds. Often the fix starts with the basics—battery/charging tests and connector inspections—before moving to sensor or module diagnosis.
