General Motors introduced a new family of competitive inline 6 cylinder engines for their ’02 SUV’s. These 6 cylinder engines were downsized to 5 and 4 cylinders for use in their ‘04 Colorado and Canyon trucks. These 4, 5, and 6 cylinder engines share some of the same components and operational characteristics as well as new service features. Some of the unique service features will be taught in class. Scan data interpretation, scope patterns and service tips will be provided to help make you more proficient.
