Diesel Equipment Technology - effective Fall 2004


The Diesel Equipment Technology Major offers both theoretical and hands-on training related to diesel equipment including diesel engines, fuel systems, electrical systems, hydraulic systems, drive trains, brake systems and suspension systems. All aspects of heavy-duty, agricultural, and transportation equipment and vehicle functions and repairs are covered. The program also prepares students to take the Automotive Service Excellence (ASE) certification exam. For students interested in a Certificate of Achievement, a Diesel certificate is available.

A student enrolling in the program should be mechanically inclined, have the desire and ability to work with his or her hands, enjoy working in a shop environment, and have the ability to provide a clean health and DMV report prior to employment.

Technological advances and continued expansion of the Diesel Equipment industry have increased the demand for well trained entry-level technicians both locally and state-wide. Students who complete the Diesel Equipment Technology program should be able to find employment as an advanced level apprentice technician.

Careers related to the maintenance and repair of diesel powered or heavy-duty machinery and vehicles are plentiful in Sonoma County and the surrounding areas. Job titles are, Apprentice Mechanic, Journeyman Service Technician, Heavy Equipment Mechanic, Fleet Mechanic. Job locations are varied throughout the region; construction companies, truck and bus shops, dealership shops, government fleet shops & independent repair shops are many of the over 500 employers in the area. An average of 15 to 20 job announcements for entry level employees (current students) are announced annually in the classroom, and employers frequently visit the campus to advertise their needs.

The employment outlook is very good to excellent as the number of retirements is currently high and construction continues. As consumerism increases, thus will the need for technicians as trucks bring all of our consumed freight to Sonoma County. The specific need locally will easily equal our current enrollment.

Course Prerequisites and Advisories:

Courses in a program of study may have prerequisites or advisories; that is, courses that must or should be completed before taking that course. Please check for prerequisites or advisories by clicking on the course numbers in the Program Requirements section.

It is important that students who are completing an Associate Degree and desire to transfer to a four-year institution meet with a counselor to plan their lower division coursework. While many majors at SRJC are intended to align with lower division major preparation required by California public universities, specific lower-division major requirements vary among individual campuses. See a counselor, visit the Transfer Center, and check Guides For Transfer in Specific Majors, and ASSIST to review transfer preparation guides for specific schools and majors.


It is recommended that all students take DET 80 before taking other DET courses.
