Ford Mustang Starter Motor: A Guide for 2012-2020 Models

Is Your Mustang's Starter Failing?

A starter motor rarely fails without giving you some warning signs. If your Mustang won't start, the first step is always to check the battery. A weak or dead battery is the most common cause of a no-start condition and has symptoms that are very similar to a bad starter. If the battery is healthy, look for these classic signs of a failing starter motor:

• Single Loud Click: You turn the key or press the button, and you hear one loud click, but the engine doesn't crank. This usually means the starter solenoid is working, but the motor itself is dead.
• Slow, Labored Cranking: The engine turns over, but it sounds sluggish and weak, as if the battery is dying. This indicates the starter is struggling to generate enough force to spin the engine properly.
• Grinding or Whirring Noise: A harsh grinding sound during startup means the starter gear is not meshing correctly with the flywheel's teeth, or the gears are already damaged. Stop trying to start the car immediately to avoid expensive flywheel damage.
• Intermittent Starting: The car starts perfectly one day but refuses to crank the next. This inconsistency often points to worn electrical components inside the starter and can be worse when the engine is hot.
• No Sound at All: If your dash lights come on but you hear nothing when you try to start the car, the problem could be the starter solenoid or the electrical circuit leading to the starter.

Choosing a New Aftermarket Starter

When your original starter fails, you have several options. For the Mustang, both OEM and aftermarket parts can be good choices, depending on your budget and needs.

OEM & Premium Aftermarket Brands

These brands offer the highest quality and reliability, often meeting or exceeding original factory specifications. They are the best choice for owners who want a fit-and-forget solution.

• Motorcraft: This is Ford's own parts brand and the true Original Equipment (OEM) replacement. It guarantees a perfect fit and original performance. For most owners, this is a top-tier, reliable choice.
• Ford Performance: While known for performance parts, their offerings for starters are less common. They are a trusted OEM source if a part is available for your specific model.
• ACDelco: As GM's OEM parts supplier, ACDelco has a strong reputation for quality that extends to parts for other makes like Ford. They often use all-new components and are considered a top-quality aftermarket alternative.
• Powermaster: This is a performance-focused brand. Their starters are often smaller, lighter, and provide more cranking torque than stock units. This makes them an excellent upgrade for modified engines with higher compression or for creating clearance around aftermarket exhaust headers, though they come at a higher price.

Standard Aftermarket Brands

These brands provide a balance of value and quality, making them a popular choice for daily drivers and budget-conscious repairs.

• MPA (Motor Parts of America): A major supplier of starters, primarily remanufactured. They offer a cost-effective alternative to new parts.
• Store Brands (e.g., Duralast): Brands from major auto parts stores offer accessible, budget-friendly options that usually come with a good warranty, providing peace of mind.

Cost of Replacing a Ford Mustang Starter

The total cost depends on the part you choose and who does the work. The job is straightforward enough for a DIY mechanic with the right tools.
