Program Information

Much has changed over the years when it comes to diesel technology, but you can get the most up-to-date instruction by choosing Iowa Western’s Diesel Technology program. This program focuses on all phases of the diesel industry, including engines, transmissions, drive axles, electrical systems, and auxiliary systems. The result for successful candidates is an Associate of Applied Science degree. In addition to important classroom instruction, students in this two-year program complete internships – most of which are paid. This will give potential employers an opportunity to see you perform in real-world environments. Many graduates are then hired by those same employers. Students typically spend twice as much time in our labs as they do in lecture. That way, they get the important one-on-one instruction along with hands-on experience. Also unique to this program is the ability to participate on a part-time basis, a plus if you’re looking for flexibility.

What will you do

The Diesel Technology program is designed to place students into the workforce upon completion of this two-year degree. This program takes a more in-depth approach by studying more specific engine designs and procedures, and the repair of those engines, including CAT, Cummins, Detroit, Mercedes, and others. Transmissions and rear axle operation and repair are also reviewed in detail. Students will have the opportunity to explore diesel-related fields through two required internships.
