Job Description


Automotive Diesel / Heavy-Duty Mechanic – Fenton, Michigan
A powerhouse service department with real volume, real leadership, and the kind of equipment heavy-duty techs actually need to do the job right. This dealership in Fenton, MI is looking for a skilled Diesel & Heavy-Duty Mechanic who can handle big jobs, tough diagnostics, and the kind of work that keeps commercial and retail customers on the road. If you want a shop where management respects your expertise, the bays stay full, and the parts department actually supports you, this is that kind of environment.


You’ll be stepping into a team that values precision, accountability, and craftsmanship — not chaos. Expect modern diagnostic tools, strong OEM support, and a service department that understands the difference between a real diesel tech and a general line mechanic. Whether you’re a seasoned master or a rising diesel specialist, this is a strong opportunity in a high-demand Michigan market.



What You’ll Do



  • Diagnose and repair diesel engines, drivetrains, emissions systems, and heavy-duty components
  • Perform maintenance, brakes, suspension, steering, and electrical work on trucks and larger vehicles
  • Handle advanced troubleshooting using OEM scan tools and diagnostic equipment
  • Communicate clearly with service advisors regarding findings and recommended repairs
  • Document all work performed with accuracy and attention to detail
  • Maintain a clean, organized, and safe work environment
  • Contribute to a professional, team-oriented shop culture


What Makes You a Strong Fit



  • Experience as a Diesel Technician, Heavy-Duty Mechanic, or Automotive/Diesel Hybrid Tech
  • Strong diagnostic abilities with diesel engines, DEF systems, and emissions components
  • Familiarity with OEM systems, scan tools, and modern repair procedures
  • Ability to manage larger, more complex repairs independently
  • Valid driver’s license and clean driving record
  • CDL is a plus but not required
  • ASE Diesel or OEM certifications are a strong advantage


What This Role Offers



  • A respected dealership with steady workflow and strong leadership
  • Competitive pay based on diesel experience and certifications
  • Flat-rate or hourly options depending on background
  • Access to OEM training, diesel certifications, and advancement opportunities
  • A well-equipped shop with heavy-duty lifts, tools, and strong parts support
  • A team environment that values skill, reliability, and professionalism
