Interested in becoming a diesel mechanic? UTI Long Beach is a diesel school near Orange, CA, with courses taught by industry professionals who supply students with the fundamentals of service and repair so that they’re ready to pursue exciting careers after graduation!1


Our Long Beach, CA, diesel mechanic school is a 45-week program where students learn to service various diesel engines through a blended learning model of online instruction and hands-on application in a lab similar to those in the professional world.7,18

This blended learning model resembles the type of continued training technicians often encounter in the field, further preparing students for the industry! The diesel training program also helps prepare students to take the Automotive Service Excellence (ASE) certification test after graduation. Not only will their courses supply them with relevant knowledge, but they can substitute their training for one of the two years of work experience required to become ASE certified.


Diesel school courses include:

  • Diesel Engines Service & Repair
  • Diesel Truck Manual Transmissions
  • Diesel Truck Brake Systems & Chassis
  • Diesel Truck Steering & Suspension Systems
  • Automotive Climate Control Systems and Repair
  • Diesel Hydraulic Systems
  • Vehicle Electronic Systems and Technology

According to the Bureau of Labor Statistics (BLS), the median annual salary for bus and truck mechanics and diesel engine specialists in the Los Angeles-Long Beach-Anaheim, CA, metropolitan area was $$65,590 in May 2022.29 This means half of diesel technicians earned more and half earned less. Keep in mind that salary depends on several factors, including experience, employer, demand and cost of living in the area.

Diesel technician skills are in demand across the country, including California. The California State Assembly's most recent data shows that agriculture, construction, manufacturing, and trade, transportation and utilities are some of the state’s largest industry sectors – all of which rely on diesel technicians to keep them running. So, it may come as no surprise that California boasted the second highest-employment level of diesel techs in the U.S. in May 2021.


UTI’s diesel mechanic training program prepares students for entry-level positions, which may include1:

  • Diesel technicians often work in repair shops, performing general maintenance and repair to several diesel vehicles.
  • Agricultural technicians typically work for dealerships or on farms, servicing planters, tractors, seeders, tillers, harvesters, and more.
  • Power generation technicians maintain, diagnose and repair equipment that provides power, such as internal combustion engines, diesel and gas generators and other engines.
  • Heavy equipment repair technicians maintain, repair, and overhaul industrial diesel-powered equipment like bulldozers and tractors.

Most of our grads start out working as entry-level technicians or in other entry-level roles. As with any industry, over time, you may be able to advance in your career with hard work. Some advanced roles may include mobile diesel mechanic, service manager, master technician, or fleet manager.77
