Heavy Diesel Technician
Interested in working with heavy equipment? Would you like to work with diesel-powered vehicles? The Gwinnett Tech Heavy Diesel program offers students the opportunity to learn the fundamentals of heavy diesel equipment and repair.
What is a Heavy Diesel technician?
A Heavy Diesel Service Technician works on diesel powered vehicles such as buses, large trucks, boats, bulldozers, dump trucks, cranes and even light-duty trucks and cars. Diesel mechanics perform a wide range of duties, from routine preventive maintenance to complete overhauls. Skills training starts with an inspection of the vehicle and progresses to use of diagnostic computer technology on today’s advanced vehicles. These tools help identify issues and determine any problems with the vehicle and corresponding corrective action. Diesel engines, being different from gasoline-powered engines have different needs and requirements when being serviced. It is essential that diesel mechanics understand the vehicle’s electrical system, powertrain and all of its working components.
Diesel engine maintenance and repair is becoming more complex as engines and other components use more electronic systems to control their operation. For example, fuel injection and engine timing systems rely on microprocessors to maximize fuel efficiency and minimize harmful emissions. In most shops, workers often use hand-held or laptop computers to diagnose problems and adjust engine functions.
Diesel technicians also use a variety of power and machine tools, such as pneumatic wrenches, lathes, grinding machines, and welding equipment.

At the time of internship placement, second semester, dealerships/shops will conduct a criminal background check on students applying for placement. A satisfactory criminal background report is conditional for internship placement.
Issues affecting a background check may hinder a student’s participation in an internship program and may prevent a student from completing the program and/or securing a job upon graduation.
Students must be at least 18 years old to start the program.
**Due to the demand and popularity of automotive programs (Automotive Technology, Ford ASSET, Heavy Diesel, Mercedes-Benz, & Mopar CAP) at Gwinnett Technical College, new students must contact AutomotiveDivision@GwinnettTech.edu immediately after applying to the college to complete a program advisement form. Acceptance into Gwinnett Technical College does not guarantee immediate placement within these programs.
