Diesel Service

Diesel Engine Repair

Diagnostics to full rebuilds on light-, medium-, and heavy-duty diesel. We find the real problem and fix it so your truck runs strong and stays out of the shop.

Engine work for trucks, commercial vehicles, and trailers

Modern Diesel keeps your vehicles moving with experienced technicians performing critical maintenance and repair. We service medium- and heavy-duty commercial vehicles, trucks of all sizes, and trailers — with the diagnostics and quality parts to get it right the first time.

What we work on

  • Power Stroke — fuel systems, regeneration, diagnostics, and emissions
  • Cummins — fuel systems, engine repairs, emissions, and diagnostics
  • Air brakes on semis and heavy-duty trucks
  • Preventative and fleet maintenance to keep engines healthy

Diagnostics first, not guesswork

A rough-running or hard-starting diesel can have a dozen causes. We use current diagnostic tools to pinpoint the actual fault, then repair it with quality parts — so you’re not paying to swap parts that didn’t need swapping.

Warranty coverage is set with your service advisor at the time of service.
