Product Description

In 2011, GM introduced the LML and LGH Duramax engines which also introduced the new Bosch CP4 high pressure fuel pump.  These systems have presented technicians with new service opportunities other shops may veer away from.  In 2017, GM introduced the L5P Duramax that included a completely new high pressure fuel system and turbocharger.

Technicians will learn operating principles of the fuel and turbocharger systems on each of the new platforms, as well as, exhaust aftertreatment systems for each application.  Technician will see fuel system replacement procedures and tips on the LML engines due to high failure rates of the CP4 pump.

After completing this class, a technician will be able to:

  • Understand the LML and LGH fuel systems
  • Diagnose and repair fuel system failures
  • Understand turbocharger systems on the LML and LGH engines
  • Introduce new L5P fuel system and electronically controlled turbocharger
  • Identify aftertreatment components and common failures
