During this course we will discuss in detail late model GM Duramax engines. Although the models presented will apply to 2010 & newer Duramax engines with full emission controls, much of the material can be applied to earlier years. After a quick update on relevant mechanical and cooling system enhancements, the air intake system will be discussed with emphasis on the variable output turbocharger design, operation, control and service. Cold starting systems will be covered. Both low and high pressure fuel systems will be described as well injectors and pressure control. Injector and fuel system lab scope patterns will be analysed and quick diagnostic tips will be shared. Late model Duramax diesel engines are equipped with full emission controls therefore EGR, Closed Crankcase Ventilation, Diesel Particulate Filter and DEF systems will be covered in detail from a ‘practical’ service perspective. Pattern failures, scope diagnostics, scan tool data and procedures will be included throughout the course.
