Diesel Service Technology

Program Description

The development of a viable Diesel training program will solve a multitude of shortcomings in the Diesel field. Technical training will enable companies to add to the expertise of their staff members by being able to hire local students at an entry level position. Students through labs and classroom situations are taught to operate state-of-the-art equipment available in today’s modern repair facilities. Students also complete courses in diesel engine, air brake systems, hydraulic brake systems, steering/suspension systems, general electric systems, multiplexing concepts, DPF concepts, preventative maintenance, introductions to marine diesel cooling systems, marine wet and dry exhaust systems, marine transmissions, marine support equipment, airport ground support equipment, and careers in the marine and aviation industries.

The curriculum is competency based using a multi-module approach to learning and is supported using the National Automotive Technicians Education Foundation (NATEF) and the Automotive Service Excellence (ASE) standards. The Diesel Service Technology program is NATEF certified. All instructors are ASE certified.

Students also receive training in soft skills, parts ordering, and Motor All-Data computerized repair information systems. Practical work experience is performed on vehicles supplied by the regional school community and simulators purchased through grants. Students are also encouraged to participate in Distance Learning, Skills USA, and a variety of activities and clubs offered at GNB Voc-Tech.

Senior students are offered the chance to test in four ASE areas of certification-diesel engines, air brakes, P.M.I., and steering/suspension. Upon passing they receive their ASE credentials after completing one more full year employment in the trade. Students are encouraged to strive for excellence in their academic and technical studies.

Upon graduation, they will have acquired the necessary skills to enter the workforce or enroll in post-secondary or technical colleges to further their education. Articulation agreements have been developed with technical colleges to reduce the cost of tuition for the students. Graduates of this program can expect to be able to find positions in the diesel field, marine industries, and aviation ground support equipment areas as entry level technicians and with experience and continued education will be able to work their way to becoming Master Technicians.
