Inspect vehicles for wear and tear
Inspecting vehicles for wear and tear is a critical part of what auto technicians do. By carefully examining a vehicle, an auto technician can identify potential problems early on, before they become more serious and expensive to repair. Some of the things that auto technicians look for when inspecting a vehicle include:
- Fluids: Auto technicians check the levels and condition of fluids such as oil, coolant, and brake fluid. Low fluid levels can indicate a leak, while dirty or contaminated fluid can damage components.
- Tires: Auto technicians check the tires for wear and tear, as well as proper inflation. Worn or underinflated tires can affect a vehicle’s handling and braking.
- Brakes: Auto technicians check the brake pads, rotors, and calipers for wear and tear. Worn brake pads can reduce a vehicle’s stopping power, while damaged rotors or calipers can cause the brakes to malfunction.
- Lights: Auto technicians check all of the vehicle’s lights, including the headlights, taillights, and turn signals. Malfunctioning lights can make it difficult to see at night or in bad weather, which can lead to accidents.
- Belts and hoses: Auto technicians check the belts and hoses for cracks, leaks, or other damage. Worn or damaged belts and hoses can cause the engine to overheat or lose power.
By inspecting vehicles for wear and tear, auto technicians can help to prevent accidents and costly repairs. They can also help to extend the life of a vehicle and keep it running smoothly.
Replace worn or damaged parts
Replacing worn or damaged parts is an essential part of what auto technicians do. Worn or damaged parts can affect a vehicle’s performance, safety, and fuel efficiency. By replacing worn or damaged parts, auto technicians can help to keep vehicles running smoothly and safely.
Some of the most common parts that auto technicians replace include:

- Tires
Replacing worn or damaged parts is not always an easy task. Some parts, such as brake pads and spark plugs, can be replaced relatively easily. Other parts, such as engines and transmissions, require more specialized knowledge and experience to replace.
Regardless of the difficulty of the task, replacing worn or damaged parts is an important part of what auto technicians do. By keeping vehicles in good condition, auto technicians can help to prevent accidents, extend the life of vehicles, and save money on repairs.
Perform scheduled maintenance services
Regular maintenance is essential for keeping any vehicle running smoothly and safely. Auto technicians perform scheduled maintenance services to ensure vehicles are in good condition and to prevent problems from developing. These services typically include:
- Oil change and filter replacement: Oil lubricates the engine and helps to prevent wear and tear. The oil filter removes impurities from the oil, keeping it clean and effective.
- Tire rotation and alignment: Tire rotation helps to ensure that tires wear evenly, which extends their lifespan. Alignment ensures that the tires are properly aligned with the vehicle, which improves handling and fuel efficiency.
- Brake inspection and adjustment: Brakes are essential for safety, so it’s important to have them inspected and adjusted regularly. Auto technicians will check the brake pads and rotors for wear and tear, and they will adjust the brakes as needed.
- Battery check and replacement: Batteries lose power over time, so it’s important to have them checked regularly. Auto technicians will test the battery and replace it if necessary.
By performing scheduled maintenance services, auto technicians can help to extend the life of a vehicle and keep it running safely and efficiently.
Diagnose and repair engine problems
Diagnosing and repairing engine problems is a complex and challenging task that requires a deep understanding of how engines work. Auto technicians use a variety of tools and techniques to diagnose engine problems, including:
