Whether you’re driving a Powerstroke, Cummins, or Duramax, there is no job too big or small. From preventive maintenance to engine replacement, Williams Diesel is the right choice for your truck. We are no stranger to late model diesel vehicles either. We can service and diagnosis issues involved with late model fuel injection, EGR, DPF and SCR emission systems.

Sprinter Service

We work on 2002-2010 Sprinter vans too! Whether it is badged as a Dodge, Freightliner, or Mercedes-Benz we’ve got you covered! These vehicles take specialized scan tools and tooling to be worked on correctly. Williams Diesel is proud to be Marion County’s Sprinter specialist.


We specialize only in diesel vehicle repair; this allows us to focus on one type of vehicle and not claim to be able to repair anything that drives down the road! We do more than just repair runability issues. We also repair fluid leaks, clutches, air conditioning systems, balance tires, service brake systems, transmissions and differentials, plus more! We’re experienced on working on vehicles from governments, counties, municipalities, fleets, businesses, farms, or just individual diesel owners and enthusiasts. Contact us today to schedule your appointment!
