Starter Motor of the 2012 Subaru Legacy: What It Does and How to Keep It Running Smoothly

The 2012 Subaru Legacy is a reliable mid-sized sedan well-known for its smooth ride and all-wheel-drive capability. Like most conventional vehicles powered by an internal combustion engine, the 2012 Subaru Legacy uses a starter motor to kick off the engine's operation every time you turn the key or push the start button. So yes, the starter motor definitely plays a key role in getting your Subaru Legacy going.

The starter motor in the 2012 Subaru Legacy is an electric motor that engages with the engine's flywheel to crank the engine and get the cylinders firing. Without the starter motor, the petrol engine simply wouldn't start. It essentially provides the initial mechanical momentum needed to start the combustion process. Once the engine fires and is running under its own power, the starter motor disengages.

So what exactly does the starter motor do? When you turn the ignition key or press the start button, an electrical signal is sent to the starter motor's solenoid. This connects the starter motor to the vehicle's battery, allowing it to draw the electrical power needed. The motor then spins, turning the engine over by engaging with the flywheel. This cranking motion allows the engine to draw in air and fuel, leading to combustion and engine start-up. The whole process happens quickly and efficiently, making starting your Legacy a seamless experience.

Like any electrical component, the starter motor can experience wear and tear over time. The commutator, brushes, and solenoid can degrade, and exposure to heat and vibration under the bonnet can affect its lifespan. Because the starter motor is crucial to starting the Legacy, maintaining it as part of your vehicle's regular servicing can save a lot of headaches down the track.

Here are a few tips and pointers on what to watch out for when it comes to the starter motor in your 2012 Subaru Legacy:

• Listen for unusual noises when starting the engine. Grinding, clicking, or a whirring sound without the engine turning over can indicate starter motor problems.
• Slow or laboured engine cranking can mean the starter motor is struggling, possibly due to worn brushes or poor electrical connections.
• Make sure your battery and its connections are in good condition. A weak or faulty battery can mimic starter motor issues.
• Check for visible signs of corrosion or damage on the starter motor terminals and wiring during regular inspections.
• If you encounter repeated starting problems, it is wise to have the starter motor tested by a qualified mechanic.

When replacing or servicing the starter motor, a few things to keep in mind:

1. Always use high-quality replacement parts specifically designed for the 2012 Subaru Legacy to ensure proper fit and function.
2. The starter motor is usually located near the bottom of the engine block. Depending on your mechanic's experience and tools, the replacement can be straightforward or moderately involved.
3. Ignoring early signs of failure can leave you stranded with a car that won't start, so timely maintenance and replacement are worth the effort.
4. Ensure electrical connections are clean and tight, and the battery is fully charged to prevent unnecessary strain on the new starter motor.

Incorporating starter motor checks into your regular vehicle servicing helps maintain the overall health of your Subaru Legacy and its starting system. Most vehicle servicing schedules will include inspection of the starting system along with the battery and charging system checks. It's a smart move to get these done regularly, especially if you live in climates with extreme temperatures or if your car is older and has clocked up the kilometres.

In the end, the starter motor is an unsung hero under the hood of the 2012 Subaru Legacy. It quietly and efficiently delivers the critical first step needed to get your car up and running every day. Keeping an eye on it and getting it serviced when needed contributes to fewer surprises and a more reliable driving experience.
