Explore rewarding Diesel Fleet Mechanic Technician II jobs, a critical mid-level role within the transportation and logistics industry. Professionals in this position are the backbone of fleet operations, ensuring that a company's vehicles—primarily medium and heavy-duty diesel trucks, tractors, and trailers—remain safe, reliable, and on the road. This career path is ideal for skilled technicians who have moved beyond entry-level work and are now taking on more complex diagnostic and repair responsibilities with greater independence. A Diesel Fleet Mechanic Technician II typically performs a wide array of duties centered on preventive maintenance and advanced repairs. Common responsibilities include executing thorough preventive maintenance inspections (PMIs) to adhere to Department of Transportation (DOT) regulations and manufacturer schedules. They diagnose and repair major vehicle systems, including diesel engines, transmissions, drivelines, braking systems (air and hydraulic), steering and suspension, electrical and electronic systems, and HVAC systems. Technicians at this level are also proficient in addressing emissions and regeneration systems on modern diesel engines. They accurately document all work performed, noting the complaint, cause, and correction, often using computerized maintenance management systems (CMMS) to track repairs and parts inventory. The role demands a strong blend of technical knowledge, problem-solving skills, and physical stamina. Typical requirements for these jobs include a high school diploma or GED, complemented by post-secondary technical training in diesel or heavy equipment repair. Employers generally seek candidates with 2-4 years of hands-on experience in a fleet maintenance environment. Industry-recognized certifications, such as those from the National Institute for Automotive Service Excellence (ASE) in Medium/Heavy Duty Truck areas, are highly valued and often preferred. A valid driver's license is essential, and a Commercial Driver's License (CDL) or permit is a significant asset, allowing for road tests and vehicle movements. Key skills include advanced diagnostic abilities using electronic software and scan tools, proficiency in welding and cutting (e.g., MIG, ARC), and a solid understanding of hydraulic systems. Physical demands are considerable, requiring technicians to stand, kneel, crawl, and lift heavy parts in various shop conditions. For those with a passion for diesel mechanics and a commitment to precision, Diesel Fleet Mechanic Technician II jobs offer a stable and respected career with opportunities for further advancement into master technician, lead, or supervisory roles. This profession is crucial for keeping commerce moving, making every repair a direct contribution to the supply chain's efficiency.
