Diesel Maintenance

Keeping commercial trucks running smoothly.


In our Diesel Maintenance technician program, you’ll gain the confidence to work with the biggest trucks on the highway.

If you’re fascinated with semi-trailer trucks, you can become part of the team that keeps them rolling smoothly down the highway. At Minnesota State College Southeast, our Diesel Maintenance technician program in Winona, Minnesota will give you the training to work with these heavy-duty vehicles and other diesel engines, such as buses and large agricultural equipment.

Our emphasis is on how to maintain, service, and repair diesel engines and transportation trailers. The program covers:

  • Computer Diagnostics
  • Drivetrain Systems
  • Electronics
  • Heating and Air Conditioning Systems
  • Preventive maintenance
  • Tractor/Trailer Brake Systems
  • Welding for Diesel Maintenance

Extra credentials
Today’s diesel and heavy-duty vehicles require computerized diagnostics to properly identify issues. MSC Southeast is the only college in Minnesota that includes Snap-on Tools Diesel Scanner Diagnostics Certification as part of its Diesel Maintenance Technician program. You’ll also be ready to test-drive and move large trucks because earning a commercial drivers’ license (CDL) is part of the program.

With a certificate or diploma from MSC Southeast, you can begin your career in diesel maintenance with a solid foundation. Employers are looking for people who have skills like these and are ready to work.
