Simple DIY Car Maintenance
If you’re comfortable getting a little dirty, you may want to take on a few routine car maintenance tasks yourself to help keep your vehicle running smoothly.
Key Takeaways
The cost of bringing your vehicle to a shop for routine service can add up over time. While repair needs vary by vehicle, there are a few simple do-it-yourself (DIY) car maintenance tasks that apply to many makes and models. Instead of relying on a mechanic for every small job, you may be able to handle some common upkeep on your own.
Before you get started, consult reliable step-by-step instructions. Consider visiting sites such as Pep Boys and NAPA Auto Parts, or watching verified video tutorials for visual guidance. You can also ask a professional if you’re unsure whether a repair is safe to do yourself.
As with any auto maintenance, make sure to reference your vehicle’s owner’s manual first. There you will find valuable information such as what type of bulb to use or how frequently you should change the car’s oil.
Common DIY maintenance tasks
Many routine car maintenance jobs are approachable for drivers with basic tools and a little time. The table below highlights common DIY tasks, why people take them on and the situations where it’s smarter – or safer – to involve a professional.
| DIY task | Why drivers do it | When to get help |
