If this sounds like the right career for you, keep reading to learn some tips you can apply after training. 

1. Keep Your Tools Clean After Auto Mechanic Training 

When working with heavy-duty vehicles, things can get messy. Servicing diesel engines, you’ll notice that the fuel is more viscous and crude and as a result, grimier than gasoline. To extend the lifespan of your tools and save money in the long run, be sure to clean your tools after each job throughout your automotive mechanic career. Remember that the time you’ll spend cleaning up is billable, as it’s considered part of the repair process. By getting into the habit of cleaning your tools after each service, you’ll record the right amount of time and charge customers the correct sum. 

After auto mechanic training, be sure to clean your tools to save money in the future.

2. Always Check Fluid Levels

As a heavy-duty mechanic, it’s important to do your due diligence to ensure that your customers’ vehicles are not vulnerable to damage in the future. One of the best ways to do this is to ensure that fluid levels are where they need to be. After auto mechanic training, make it a priority to perform preventative maintenance tasks like checking fluid levels and adjusting them accordingly. Be sure to check engine oil, antifreeze, coolant, power steering fluid, windshield washer fluid, brake fluid, diesel exhaust fluid, and transmission fluid. These all play a vital role in every aspect of a vehicle’s functioning and longevity. When they’re too low, engine corrosion can occur. 

3. Safety Precautions To Remember When Working With Heavy-Duty Vehicles

As a heavy-duty mechanic, the equipment and chemicals you’ll work with will require diligent attention to safety precautions on your part. To stay safe and healthy after heavy-duty mechanic training, be sure to wear the appropriate PPEs like goggles, gloves, and flame-resistant coveralls.
