Parts for your 2013 Subaru Forester-Starter motor

2013 Subaru Forester starter motor — what it does and how to look after it

Based on technical documentation, a starter motor is absolutely relevant to the 2013 Subaru Forester. The Subaru Factory Service Manual for the SJ-series Forester (Starting/Charging System section, published via Subaru Technical Information System) details the starter assembly, relay, and control circuit. The Subaru electronic parts catalogue for 2013 Forester engines (FB20/FB25 petrol, FA20 turbo petrol, and EE20 diesel in some markets) lists dedicated starter motor part numbers, and OE supplier catalogues such as Denso’s aftermarket listings specify direct-fit starters for these models. This vehicle is not a hybrid and does not use an integrated starter‑generator, so a conventional 12‑volt gear‑reduction starter is fitted.

On a 2013 Forester, the starter motor’s job is simple but critical: it cranks the flat-four engine fast enough for fuel and spark to take over. It engages the flywheel or flexplate via a small pinion, then disengages the moment the engine fires. It’s mounted at the top of the transmission bellhousing. On turbo XT variants the intercooler may need to come off for better access, while naturally aspirated models are generally reachable from the engine bay.

Typical signs of starter trouble include a single click with no crank, slow or laboured cranking, a grinding noise on engagement, or intermittent no‑start when hot. Before blaming the starter, it’s smart to check the battery health, clean the main battery and chassis earth connections, and confirm the starter relay/ignition switch are behaving. High compression EE20 diesel models are especially sensitive to a weak battery.

When replacement is due, disconnect the negative terminal first. Ensure the vehicle is in Park (CVT) or Neutral (manual) with the handbrake on. Remove the intake ducting or intercooler if required, label the small signal wire, and support the heavy cable. Refit with clean mating surfaces, route cables away from heat, and torque the mounting bolts to the specification in the Subaru service manual. There’s no special programming after a starter swap on this model—once the battery is reconnected, it should be ready to crank.

• Good practice during servicing: test battery and charging voltage, inspect starter wiring and earth straps, listen for abnormal engagement noise, and check for oil leaks that could contaminate the starter.
• If the pinion or flywheel teeth are noisy or chewed, have the ring gear inspected before refitting a new starter.
• Choosing an OE‑quality unit (common OE is Denso) helps ensure correct fit and long life.

With sensible maintenance, a Forester’s starter typically lasts well over 150,000 km, but heat, oil contamination, or low voltage cranking can shorten its life.

Popular questions

Does the 2013 Forester have stop‑start and a special starter?

No, Australian and New Zealand 2013 Forester models were not sold with idle stop‑start. They use a conventional 12‑volt gear‑reduction starter. Petrol and diesel variants use starters matched to their engines, but the operating principle is the same.

How long does a starter motor last on a 2013 Forester, and what are the warning signs?

Many last the life of the vehicle, but 150,000–250,000 km is common. Warning signs include slow cranking, a single click with no crank, grinding on engagement, and intermittent no‑start when hot. Always rule out a tired battery or poor earths before replacing the starter.

Can a 2013 Forester be push‑started?

Manual models can sometimes be push‑started in an emergency if the battery has some life, but it’s not recommended as routine—it can be hard on the drivetrain and catalytic converter. CVT models cannot be push‑started, a jump‑start or proper diagnosis is the way to go.
