Starter Motor for the 2012 Subaru Forester: Purpose, Maintenance and Replacement Advice

The 2012 Subaru Forester is equipped with a traditional starter motor as part of its ignition system. Like most petrol and diesel vehicles of its era, the starter motor is absolutely essential for getting the engine running. So if you own or are looking after a 2012 Forester, understanding how the starter motor works and when it might need attention can save you a headache or two down the track.

Simply put, the starter motor is what kicks the engine over when you turn the key or press the start button. It is an electric motor that engages with the engine's flywheel, spinning it fast enough for the engine to begin its own combustion cycle. Without the starter motor, the engine just won't start. It relies on a battery to supply power, and the motor itself is made to withstand repeated, short bursts of high current.

While newer vehicles with hybrid or fully electric drivetrains might not have a conventional starter motor, the 2012 Forester definitely has one. Its Boxer engine needs that initial spin to wake from its resting state and get running. This is very different from electric cars where an electric motor doubles as the propulsion and starting unit, or hybrids with more complex starting strategies.

Now, when it comes to keeping the starter motor in tip-top shape, there are a few tips and tricks worth knowing. Generally, starter motors are pretty durable but they do wear out over time - especially if the vehicle experiences lots of short trips, or if the battery and electrical system are not in good order. A weak battery will often cause the starter motor to strain, which can speed up its decline.

Here's what a typical maintenance routine might involve for a 2012 Subaru Forester's starter motor:

• Regular battery checks: Make sure the battery is healthy and fully charged. A low voltage battery puts extra load on the starter motor.
• Inspect electrical connections: Corrosion or loose wiring at the starter motor terminals can cause poor performance or failure.
• Listen for unusual noises: Grinding, clicking or whining sounds during starting can indicate the starter motor's pinion gear or the flywheel ring gear is wearing out.
• Avoid long cranking cycles: If the engine doesn't start after a few seconds, give it a break instead of holding the key turned over. Overheating the starter motor can cause damage.

If you do experience starter motor failure, replacement isn't typically too tricky or expensive for the 2012 Subaru Forester. You'll want to make sure you choose a quality replacement part, preferably OEM or a reputable aftermarket brand specialised in Subaru parts. Having a mechanic replace it is usually recommended unless you're confident with DIY repairs, as starter motors can be a tight fit and require some electrical know-how.

When replacing the starter motor, it's a good idea to also check and potentially replace the related components such as the starter solenoid, wiring harnesses and battery connections. All these bits work together to ensure smooth operation. Failing to address these can risk premature failure of the new starter motor.

All up, the starter motor is one of those unsung heroes in the 2012 Subaru Forester. It takes the heat when it's time to get going and generally doesn't ask for much in return beyond a healthy battery and good wiring. With some basic maintenance awareness, owners can keep their older Foresters starting reliably for many years.
