2008 Subaru Impreza Starter Motor — What It Does and How to Look After It

Yes, the 2008 Subaru Impreza absolutely uses a conventional 12‑volt starter motor. This is documented in the Subaru Factory Service Manual for the GE/GH/GR series (Starting System section), the Subaru Technical Information System service publications, and Subaru’s genuine parts catalogues, which list a starter motor assembly for both petrol EJ-series and the EE20 diesel variants. General workshop references such as the Haynes Subaru Impreza (2001–2011) manual also cover starter testing and replacement on this model year.

The starter motor’s job is simple but crucial: it spins the engine’s crankshaft via the flywheel ring gear so the engine can fire up. When the key is turned (or the start request is made), the solenoid pushes the pinion into the ring gear and powers the motor. Once the engine catches, the pinion retracts and the starter is out of the game until the next start.

Typical warning signs that the starter may be on the way out include a single click with no crank, slow or laboured cranking even with a healthy battery, intermittent no‑start that improves with a light tap on the starter body, or grinding noises as the pinion or ring gear wears.

• Before blaming the starter, check battery state of charge and terminals, main grounds, the starter relay, and the ignition/clutch or neutral safety switch operation.
• Voltage‑drop testing across the positive feed and engine earth will quickly pinpoint wiring or connection issues.

Replacement on a 2008 Impreza is straightforward for a competent home mechanic: disconnect the negative battery terminal, raise the vehicle safely, and access the starter at the rear of the engine where it meets the gearbox. Remove the main battery feed and signal connector, then the two mounting bolts. Fit the new unit, reconnect, and verify clean, tight terminals. Many techs prefer genuine or high‑quality remanufactured starters to avoid repeat faults.

As part of regular servicing, it’s worth cleaning battery posts, inspecting engine and chassis grounds, and listening for any abnormal starter noises. Short‑trip driving, heat soak, oil leaks, and tired batteries are common contributors to premature starter wear. With good electrical health, these starters often see 150,000–250,000 km or more.

Note for manual vs auto: manuals rely on the clutch switch being fully depressed to allow cranking, automatics need the selector firmly in Park or Neutral. If there’s no crank, verify those interlocks first.

Popular questions about 2008 Subaru Impreza starter motors

Does a 2008 Subaru Impreza have a starter motor?
Yes. All 2008 Impreza internal‑combustion models use a 12 V starter motor with a solenoid that engages the flywheel ring gear. This is covered in Subaru’s Factory Service Manual and parts catalogues for the GE/GH/GR range.

Where is the starter on a 2008 Impreza?
It’s mounted at the rear of the engine where it joins the transmission, bolted to the bellhousing. You’ll find the main battery cable and a small signal wire attached. Access is usually from above and below, removing the intake ducting or undertray can help.

How long do they last and what does replacement cost?
With a healthy battery and clean connections, many last 150,000–250,000 km. In Australia and New Zealand, parts typically run from a few hundred dollars, and labour is often about 1.0–1.5 hours. Total fitted cost commonly sits in the AU/NZ$450–$1,100 range, depending on part quality and workshop rates.
