Course Description

This course is an in-depth study of engine diagnostics and repair techniques. Much of the class time is spent with on-iron activities, diagnosing and correcting engine problems. Participants learn basic diagnosis and troubleshooting procedures, use of Caterpillar diagnostic tools, and use of Caterpillar reference material. The four major engine systems studied are oil, air, cooling, and fuel. DST 110 and DST 113. Prerequisites: Provide a dealer letter indicating secured internship at a participating Caterpillar Dealership. Audit available.

Intended Outcomes for the course

At the completion of this course, the student will be able to use Caterpillar service literature and diagnostic tooling to troubleshoot problems with diesel engine lubrication, air, cooling, and fuel systems. Acquired skills include the following:


·            Select proper oil grades, viscosities, and additive packages for Caterpillar Engines

·            Measure and evaluate temperatures and pressures throughout the oil and air systems of an operating engine

·            Calculate coolant temperature and pressure differential across an engine or radiator

·            Evaluate horsepower and fuel rates

·            Determine the effects on a mechanically governed engine€™s set point, horsepower, and boost caused by changing fuel settings, high idle, and timing.

·            Measure and adjust dynamic timing advance on a mechanically governed engine

Course Activities and Design

This is an outcome based course utilizing a lecture/lab format. This course includes videos, assignments, demonstrations, lectures, and hands on learning. Course will be taught using Caterpillar equipment and curriculum.
