Diesel Mechanics/Heavy Truck Maintenance

Program Outline

Instruction Sets
Your program consists of 10 Instruction Sets written to take you step-by-step through the knowledge and skills you'll use in your new career.

Computer Specifications
As you know this is an online academic program. This means you will need high-speed internet access to begin your program. In addition, you will need access to a Microsoft® Windows® based computer running Windows 7® or later or an Apple® Mac® computer running OS X® or later, and an email account to participate in and complete your program.

Here's how it works: You receive the first course as soon as your enrollment has been accepted, and other courses will follow as you complete your exams. You can earn your Career Diploma in as little as a year. Here is an overview of what you'll learn and the order in which you'll access your lessons:

Program Goal and Outcomes

Program Goal: The Diesel Mechanics/Heavy Truck Maintenance Career Diploma program provides students with knowledge of skills ranging from basic diesel engine operations to troubleshooting and repair. Students will learn how to maintain and do repairs on their own trucks, work for a truck fleet or dealership, or start a full- or part-time business.

Program Outcomes:
Upon completion of the program, students will be able to:

  • Recognize the role of a diesel repair technician and the many exciting career opportunities available to skilled technicians
  • Identify common tools and shop safety procedures used in the repair of heavy-duty vehicles
  • List the basic operation of a diesel engine and its major components
  • Describe the operation of the cooling and lubrication systems of a typical diesel engine
  • Identify the various procedures used in the inspection and rebuilding of a typical diesel engine
  • Explain the operation of a mechanical fuel injection system, the fuel-delivery system, as well as the properties of the various types of diesel fuels
  • Recognize the basics of electrical and electronic engine control systems
  • Recognize the basic operation and repair of heavy-duty truck steering and suspension systems, along with service and repair of vehicle wheels and tires
  • Identify the operation of hydraulic and pneumatic braking devices and control systems, the interpretation of fault-indication messages, and the troubleshooting of brake system problems
  • Describe the operation and repair procedures for common heavy-duty truck manual transmissions and clutch systems
  • Identify the principles of operation, troubleshooting steps, and repair procedures for the most common types of automatic transmissions used in today's heavy-duty trucks
  • Identify the function and operation of driveline components, troubleshooting procedures, and the tasks required for servicing driveline problems
  • Recognize the function and operation of heating, ventilation, and air conditioning systems used on heavy-duty trucks
