Effective Fall 2022

Students develop the skills necessary to repair and maintain diesel-powered highway, industrial, and marine vehicles and equipment. Advanced diesel maintenance techniques and principles are applied in diagnosing malfunctions and prescribing corrective action. The course work emphasizes diesel service management, as well as the theory and skills of refrigeration, electronic and mechanical fuel injection, advanced emission diagnostic and repair, chassis maintenance, vehicle inspection, tune-up, engine overhaul, transmission repair, brake service, and handling hazardous waste. The curriculum provides exposure to all facets of the industry with specific emphasis on problem solving and transferability of skills. Graduates are prepared to take the Pennsylvania Vehicle Safety Inspection examinations, National Institute of Automotive Service Excellence (NIASE) examinations in heavy truck mechanics, Stationary Refrigeration exam (608), Motor Vehicle Air-conditioning exam (609), Allison Transmission certification, Daimler “Get Ahead” Detroit/Freightliner certification, and Level I Eaton Hybrid certification.

Career Opportunities

Heavy duty truck technician for truck dealership, independent garage, truck fleet, leasing company or contractor; the natural gas industry; technical service representative for diesel engine manufacturer or distributor; and diesel service occupations such as service writer, warranty writer, parts manager, service manager, transport refrigeration technician, and automated driveline and fuel system specialist.

Special Equipment Needs
