DIY is possible for mechanically inclined individuals. However, if you are not comfortable working on your car, professional installation is recommended.

Here's a comparison of your buying options:

• Used OEM: These are genuine factory parts that have been tested and inspected. They offer excellent value at a lower price.
• Refurbished OEM: These are factory parts that have been professionally restored with new components.
• New Aftermarket: These are brand new parts made by third-party manufacturers to meet OE specifications.

All three options can be good choices depending on your budget and needs.

Parts commonly replaced or checked at the same time:

• Battery: A weak battery can put extra strain on the starter.
• Battery Cables: Corroded or damaged cables can prevent the starter from getting enough power.
• Solenoid: The solenoid is part of the starter and may need replacement.
• Ignition Switch: A faulty ignition switch can prevent the starter from engaging.

Replacing these parts can prevent repeat failures and ensure the starting system is working properly.

A starter motor typically lasts 5-7 years or 75,000-100,000 miles.

Factors that affect longevity:

• Driving Habits: Frequent short trips can shorten the lifespan of the starter.
• Climate: Extreme temperatures can affect the starter's performance.
• Maintenance: Proper maintenance, such as keeping the battery terminals clean, can extend the starter's life.
• Oil Leaks: Oil contamination will dramatically shorten lifespan.
