All three tracks will focus on general knowledge of the vehicle and its engine components, learning how to troubleshoot problems, and using computer software to run diagnostic procedures.  The differences come in the type of vehicles students will learn to service.

Medium/Heavy Duty Diesel

Medium/Heavy Duty diesel technicians will work on diesel engines and vehicles designed for shipping, farming, construction, and more such as semi-trucks, buses, and rail engines. 

Light Duty Diesel

Light Duty diesel technicians will focus on 8.0 liter diesel engines and smaller which are designed for on-the-road consumer cars and trucks as well as compact tractor and skid-steer engines.

Mack/Volvo DATE

The Diesel Advanced Technology Education or DATE program, will train students to become a Professional Level Mack and Volvo technician upon graduation!  This certification will give graduates the ability to find immediate employment at any of the hundreds of Mack and Volvo dealerships across the country.

Our students train with the same tools and latest equipment that is found in service centers and dealerships across the nation. Whether it’s on the shop floor, in the live engine room, or on the diesel dynos, most of the training in these courses will be hands-on utilizing diesel training aids from: Cummins, Detroit, Caterpillar, Mack, Volvo, DuraMax and many more.

As a student in one of the College of Applied Technologies' diesel programs, you could also obtain your CDL.  Within the CDL courses, students will gain classroom and hands-on knowledge needed to pass the state exam with one of our several big rigs and a specially designed course. Best of all, UNOH will pay for the fees to sit for the Ohio Class A state license which can be transferred out of state.
