Heavy duty truck technicians, along with automotive technicians, diagnose, troubleshoot and repair small car to large truck malfunctions to minimize time removed from service. Preventive maintenance is a major responsibility of the entry-level mechanic. The mechanic inspects the vehicle visually to determine the need of repairs and provides routine tests and maintenance. The Automotive/ Heavy Duty Truck Technician must have a thorough knowledge of car and truck components and be competent in safety, inspections, tune-ups and troubleshooting. In the program students move throughout the Automotive/Diesel Technology areas repairing all types of vehicles including passenger cars, light and heavy duty trucks, vans, sport utility vehicles, and two and four wheel drive vehicles.

Students are expected to:

  • Possess basic mechanical interest and aptitude
  • Be able to work cooperatively in teams
  • Be self-motivated to work independently
  • Read and write at or near grade level
  • Be able to learn required math specific to the program
