Effective Fall 2020

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. 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 commercial truck technician for a truck dealership, independent garage, truck fleet, or leasing company; contractor or transport refrigeration technician; field service technician representative for diesel engine manufacturer/distributor and the natural gas industry.

Remediation Strategies

All students must remediate developmental requirements within the first year. The order of remediation will be math and English.

Program Goals

A graduate of this major should be able to:
  • practice approved safety procedures in various work situations.
  • read and interpret vehicle and component service manuals and write clear, accurate, and complete service reports.
  • diagnose and repair mechanical and electronic fuel injection malfunctions.
  • demonstrate the correct use of basic hand tools, special tools, and testing equipment.
