Diesel mechanics and service technicians maintain and repair large vehicles and other machinery that run on diesel fuel and typically do the following:

• Use scanning tools and diagnostic software to identify issues
• Interpret diagnostic tests
• Inspect engines, suspension, brake and steering systems, exhaust systems and transmissions
• Repair or replace mechanical or electrical equipment components
• Perform routine care and maintenance, such as changing oil, checking fluid levels, and rotating tires

How to Become a Diesel Mechanic

You not only need hands-on training to become a diesel mechanic; there is also an important classroom component which is why its important to attend a diesel mechanic training program at a vocational or trade school.
