Level 3:  Heavy-Duty NGV Maintenance and Diagnostics Training
>>Back to Vehicle Training


The number one challenge facing heavy-duty NGV technicians is how to distinguish between a fuel quality problem, a fuel system problem or an engine problem. This course is the only training available that treats these three elements as a system and helps technicians understand how they are interrelated.

Level 3:  Heavy-Duty NGV Maintenance and Diagnostics Training prepares technicians to understand the operation, maintenance, diagnosis and repair of heavy-duty natural gas vehicles.

Emphasis is placed on the safety knowledge and repair practices that are unique for heavy-duty natural gas engines. The course covers the components of all CNG fuel systems (regardless of manufacturer), as well as the Cummins ISL G and ISX12 G engines. 


The course includes operational theory with more than a dozen hands-on exercises. It is a perfect prerequisite to fuel system or engine manufacturer training. This course also helps prepare technicians for the ASE H1 exam.


Please note that NGV Essentials and Safety Practices (Level 1) is a required pre-requisite for both Heavy-Duty NGV Maintenance and Diagnostics Training (Level 3) and CNG Fuel System Inspector Training (Level 2).
