If you’re seeking a career with stability, you should know that always-on industries like logistics and shipping help to maintain a steady demand for diesel and fleet maintenance technician jobs. At Pennco Tech, we provide a Diesel Technology program near you at our Blackwood, NJ, campus, which covers essential topics for a career in fleet maintenance. Here, we discuss fleet maintenance jobs and how certain industries help sustain demand.

Key Takeaways

• Fleet maintenance involves inspecting, servicing, and repairing commercial vehicles, often with diesel engines.
• Always-on industries like logistics, transportation, and utilities help promote steady demand for diesel fleet technicians because they require consistent operation and preventive maintenance.
• Fleet technicians need a broad skill set across preventive maintenance, electrical systems, diagnostics, and repair, which they can learn through Pennco Tech’s Diesel Technology program.
• Fleet work stays consistent because of the constant demand that always-on industries have, as well as compliance with strict federal guidelines that mandate routine maintenance and inspections.
• To advance in a fleet career, consider earning a specialization from Automotive Service Excellence (ASE) or working your way up to higher-level roles.

What Is Fleet Maintenance, and Who Uses It?

Fleet maintenance is the process of inspecting, servicing, and repairing commercial vehicles and business equipment, including those with diesel engines. The goal of fleet maintenance is to keep vehicles working properly and safely, reducing unexpected malfunctions, decreasing repair costs, and prolonging vehicle lifespan. Industries that rely on fleet maintenance include:

• Delivery
• Logistics
• Transit
• Utilities
• Construction

These always-on industries require heavy machinery and transport fleets that must operate continuously, meaning fleet technicians are needed to meet this demand. Fleet maintenance can be done at either in-house fleet shops or dealerships/service providers. Generally, in-house shops provide greater control and tailored expertise for larger fleets, while outsourced dealerships and service providers are more suited to smaller or mixed fleets.

What Do Fleet Diesel Techs Do Day-to-Day?

Fleet diesel technicians have a wide range of daily responsibilities that help keep fleets up to date, in compliance with guidelines, and functioning optimally. They include:

• Running computer diagnostics
• Performing scheduled preventive maintenance (PM) and inspections
• Troubleshooting and repairing problems with brakes, electrical systems, batteries, etc.
• Replacing worn-out or malfunctioning parts
• Documenting all work to keep fleets safe and compliant

Fleet diesel technicians can work in dealerships, service providers, or in-house fleet shops. Wherever they work, fleet techs need to be well-rounded with knowledge of many different vehicle systems, not just engine repair and Pennco Tech’s Diesel Technology curriculum is designed to help students build that broad technical foundation.

Why Does Fleet Work Stay Busy?

Fleet work stays consistently busy, making this career path a good choice for those looking for a steady career and job security. One reason fleet work stays busy is because of routine preventive maintenance. Diesel fleets have regularly scheduled maintenance services to catch problems early and prevent unexpected downtime. Experienced fleet techs are needed to maintain these vehicles on a predictable schedule.

Another reason that fleet work stays busy is because of federal guidelines that enforce strict operational limits. These guidelines require regular inspections and repairs to keep fleets in compliance. Fleet techs perform these duties and document them, helping fleets comply with regulations. The scheduled maintenance, inspections, and repairs keep fleet technicians busy throughout the year.

Career Stability and Advancement in Fleet Work

With a consistent demand for fleet maintenance, fleet technicians stay busy and often have steady schedules. The consistency of the schedule will depend on the nature of the role. Some find employment at an in-house shop or dealership, while others become mobile road technicians and work in different areas. Schedules, workload, and earning potential typically vary by employer, role, and experience.

Fleet technicians can also specialize in certain areas, such as electrical, hydraulics, and reefer units. Specialization can often lead to greater earning potential because of the specific knowledge the techs possess. Fleet technicians can also advance their careers by working their way up to higher roles, such as lead tech, foreman, or shop manager.
