Advanced Diesel
Learn to diagnose, troubleshoot, and reassemble.
Our Advanced Diesel graduates are among the best and brightest in the industry.
Building on the skills and techniques from the Diesel Technology core program, you’ll spend your 12 weeks in Advanced Diesel learning how to diagnose and repair a Class 8 Truck, as well as complete a multipoint inspection to make trucks DOT roadworthy upon completion. Along the way, you’ll learn troubleshooting and repair; take an in-depth exploration of electrical and mechanical systems; and learn the ins and outs of modern emissions.
Get dirty, work hard, and experience what it’s like to work in a fully functioning truck shop.
What You’ll Learn in Just 12 Weeks
Diagnose, Troubleshoot, and Repair
Disassemble, diagnose, and rebuild a truck to DOT road-worthy
Electrical, Mechanical, and Emissions
Take an in-depth exploration of electrical and mechanical systems and learn the ins and outs of modern emissions.
Phase I
We start by performing a pre-delivery inspection (PDI) of the trucks you’ll work on during the program… then, we tear them all down and let the (literal) dirty work begin. In this first half of the program, you’ll learn how to navigate and use OEM websites for Cummins, CAT, PACCAR, and Detroit engines; look up torque values; complete a full inspection of the emission system and aftertreatment system on a functioning truck; troubleshoot ABS and traction control, then order replacement parts as needed; troubleshoot and repair the air system; troubleshoot an electrical system, including lights and circuits; and learn how to navigate OEM software, and do a complete tune-up on a CAT engine, a Detroit engine, a PACCAR engine, or a Cummins engine.
- Conduct proper PDI inspection
- Create parts lists and order parts
- Learn about dual air systems
- Perform a dual air system function test
- Ensure ABS and traction control systems are functioning correctly
- Learn about the emission and aftertreatment systems
Phase II
You’ll spend most of this phase putting your trucks back together, replacing/repairing pieces as you go. This includes pulling transmissions and clutches to inspect them, then replacing (as needed) and reinstalling; pulling a differential to inspect, then replacing (as needed) and reinstalling; checking the cooling system; checking the charge air cooler for leaks; inspecting the fifth wheel for tightness and adjustability; perform steering checks and repairs; and performing and monitoring a complete regeneration of the emissions and aftertreatment systems; perform a final pre-delivery inspection (PDI) before returning the truck to the customer.
- Pull transmissions
- Pull differentials
- Perform clutch replacement and reinstallation
- Perform emission and aftertreatment testing
- Perform a final PMI
