Parts for your 2016 Subaru Forester-Starter motor

2016 Subaru Forester starter motor: purpose, care and when to replace

According to Subaru’s Factory Service Manual for the SJ-series Forester (2015–2018) and the Subaru Technical Information System, the 2016 Subaru Forester is fitted with a conventional 12‑volt starter motor (Denso type) across its petrol and diesel variants. Subaru’s parts catalogues for the FB25 2.5L, FA20F 2.0T, and EE20 diesel list a dedicated “starter motor assembly,” confirming the part is absolutely relevant to this model. Even Foresters equipped with idle stop–start in some markets still use a reinforced starter and suitable battery to handle frequent restarts.

The starter motor’s job is simple but crucial: it spins the boxer engine fast enough for fuel and spark to take over, getting the Forester up and running every time the key’s turned or the start button’s pushed. When it’s healthy, starts are crisp and quick, when it’s tired, drivers may hear a single click, slow cranking, or a nasty grind.

There’s no fixed service interval for the starter, but a bit of care during regular servicing goes a long way:

• Check the battery and charging system — low voltage is the number one starter killer.
• Clean and tighten battery terminals and engine earth straps.
• Listen for slow cranks or intermittent clicks, catch issues before they leave someone stranded.
• Keep an eye out for oil leaks from the rocker covers or rear main — oil on a starter shortens its life.

Replacement on a 2016 Forester is straightforward for a trained tech: disconnect the negative terminal, raise and support the vehicle safely, remove the starter’s electrical connectors and mounting bolts at the bellhousing, swap in a quality new or remanufactured unit, torque to spec, and verify cranking speed and voltage drop. On CVT models, ensure the inhibitor switch and starter relay logic are behaving before condemning the motor itself.

Quality matters. OEM or reputable remanufactured Denso units tend to crank faster and last longer. In Australia and New Zealand, expect roughly 1.0–1.5 hours labour, with parts commonly ranging from mid-hundreds depending on brand. Starters often last well beyond 150,000 km, but frequent short trips, stop–start traffic, or a weak battery can bring that forward. If the Forester is hesitating on cold mornings or clicking without cranking, it’s time for a proper test and likely a replacement before the next roadie.

Popular question: What are the common signs my 2016 Forester’s starter is failing?

Classic tells include a single click with no crank, slow cranking even with a healthy battery, an occasional grind as the pinion doesn’t fully engage, or intermittent starts that get worse over weeks. Always rule out the battery and corroded terminals first, as they can mimic starter faults.

Popular question: Can a bad battery damage the starter on a 2016 Forester?

Yes. Repeated low-voltage cranking overheats the starter and solenoid, wearing brushes and contacts early. If starts are sluggish, test and replace the battery or fix charging issues before the starter cops the blame.

Popular question: Is there a serviceable relay or fuse to check before replacing the starter?

There is. The Forester has a starter relay and relevant fuses in the under‑bonnet fuse/relay box. Verifying relay operation, neutral/park position switch (CVT) or clutch switch (manual), and doing a voltage drop test across the starter circuit can save replacing a good unit.
