Parts for your 2014 Subaru Impreza-Starter motor

2014 Subaru Impreza starter motor: what it does and how to look after it

Based on technical sources, the 2014 Subaru Impreza does use a conventional starter motor. The Subaru 2014MY Impreza Service Manual (Starting/Charging System – Starter) details a reduction‑gear, solenoid‑actuated starter for the FB20 engine, and the Subaru parts catalogue (Group 23 Electrical – Starter, p/n prefix 23300) lists the starter assembly for this model. So the starter motor is absolutely relevant to any 2014 Subaru Impreza, whether it’s a manual or CVT.

On this Impreza, the starter motor’s job is to spin the crankshaft fast enough for the FB20 2.0‑litre boxer to fire. Turn the key or press Start and the solenoid throws the pinion into the flywheel ring gear, the reduction gears multiply torque, and the engine lights off. Once running, the pinion pulls back and the alternator takes over electrical duties.

The starter isn’t a regular “replace by kilometres” service item, but it does appreciate a bit of care during routine servicing. Under the bonnet, clean and tighten the battery posts and the main starter cable, and make sure the engine earth straps are tidy. If the car does mostly short trips, have a load test done on the battery and a quick voltage‑drop test across the starter circuit. Keep an eye out for oil weeping onto the starter from nearby gaskets, as contamination can shorten its life.

• Common signs of starter trouble: a single click with no crank, slow or laboured cranking, intermittent no‑crank even with good lights, or a harsh grind as the pinion meets the ring gear. Similar symptoms can also come from a weak battery, corroded terminals, a failing starter relay, or the clutch/neutral safety switch, so test first.

Replacement is straightforward for a competent home mechanic, but many owners prefer a workshop. Disconnect the negative battery terminal, then access the unit at the top rear of the engine where it meets the gearbox. Remove the air intake ducting for space, unplug the signal connector, undo the main battery cable, and remove the two mounting bolts. Fit an OE‑quality or reputable remanufactured unit, reuse any heat shields or spacers, and torque the fasteners to the specs in the Subaru service manual. After refitting, check charging voltage (around 13.8–14.5 V with the engine running) and confirm crisp, clean cranking. With fresh terminals, a healthy battery, and tight grounds, the 2014 Impreza’s starter should rack up plenty of kilometres without drama.

Popular questions

Where is the starter motor on a 2014 Subaru Impreza?
It sits under the bonnet at the top rear of the engine, right where the engine and gearbox meet. On most cars it’s easiest to reach from above after removing the air intake ducting, some techs also pop the battery out for extra elbow room.

How long should the starter last?
With good battery health and clean connections, many Impreza starters run 150,000–300,000 kilometres. Lots of short trips, weak batteries, or oil contamination can shorten that, while regular electrical checks during servicing help it last longer.

What should be checked before replacing the starter?
Rule out a flat or failing battery, corroded terminals, dodgy earth straps, a bad starter relay, and the clutch/neutral safety switch. A quick voltage‑drop test across the cables often reveals issues that mimic a bad starter.
