Parts for your 2010 Subaru Exiga-Starter motor

2010 Subaru Exiga starter-motor: what it does, how it fails, and when to replace it

Referencing technical sources: the 2010 Subaru Exiga (YA series) absolutely uses a conventional 12‑volt starter motor. This is documented in the Subaru Exiga YA Workshop/Service Manual under Electrical – Starting System (which describes the starter, solenoid and ring gear operation) and in the Subaru FAST parts catalogue for YA5/YA9, Group 23 – Starter, which lists the complete starter assembly and related components. Many Exiga variants use a Denso starter typical of EJ‑series and EJ/FB‑era Subaru engines. So yes—starter‑motor is relevant and fitted on the 2010 Subaru Exiga.

For this model, the starter‑motor’s job is simple but vital: it spins the boxer engine fast enough for the ECU to fire fuel and spark, getting the Exiga running. Turn the key or press start, the solenoid kicks the gear out to mesh with the ring gear, the motor cranks, and off it goes.

As part of regular servicing, it’s smart to give the starting system a once‑over. Many “starter problems” are actually poor battery condition or dodgy connections, so checking the battery, cleaning terminals, and inspecting the main starter cable and earth strap can save a lot of grief.

• Common signs it’s on the way out: single loud click with no crank, very slow cranking even with a healthy battery, intermittent no‑start when hot, or a grinding/whirring sound as the pinion fails to engage properly.
• Typical lifespan varies, but 150,000–250,000 km is pretty normal, depending on usage and heat.

Replacement advice for a 2010 Exiga: disconnect the negative battery terminal, then access the starter at the top/rear of the engine where it bolts to the bellhousing. On many Exiga variants, removing the airbox or intake ducting makes life easier. Unplug the solenoid connector, remove the battery cable from the stud, then undo the mounting bolts. When refitting, use a quality new or remanufactured unit, ensure clean, tight electrical connections, and inspect the ring gear for damage. If there were slow‑crank issues, a quick voltage‑drop test across the main cables helps confirm the wiring’s healthy.

A few extra tips: heat‑soak and short‑trip driving are tough on starters, regular battery checks and keeping terminals spotless go a long way. If the car’s auto, confirm the inhibitor (neutral safety) switch is behaving before condemning the starter. And if the crank speed still seems lazy after a new unit, check the engine and chassis earths—Subarus are fussy about good grounds.

• Where is the starter motor on a 2010 Subaru Exiga?
  It’s mounted high on the bellhousing at the rear of the engine, near the centreline. From the top, remove the air intake plumbing or airbox for clearer access to the electrical connections and the two main mounting bolts.
• How much does replacement usually cost in AU/NZ?
  As a ballpark, Australian workshops often quote around AUD $450–$950 fitted, depending on whether it’s new OEM, reman, or aftermarket. In New Zealand, expect roughly NZD $500–$1,100. Prices vary with engine variant, parts brand and workshop rates.
• What should be checked before replacing the starter?
  Test the battery (state of charge and load), clean and tighten battery and earth connections, confirm the starter relay and inhibitor switch are working, and do a quick voltage‑drop test on the main positive and earth cables while cranking.
