Claim This BusinessAbout Central Iowa Diesel
Central Iowa Diesel operates from De Soto, Iowa, as a specialized diesel engine repair facility holding a 4.9-star rating across 34 customer reviews. The shop maintains standard business hours Monday through Friday, opening at 8 AM and closing at noon before resuming from 1 PM to 5 PM. This contractor focuses exclusively on diesel-powered vehicles, serving truck owners throughout the De Soto area who require engine diagnostics, transmission work, or drivetrain repairs.
The facility claims expertise across three major diesel engine platforms: Cummins, Duramax, and Powerstroke, representing the dominant diesel powertrains found in pickup trucks from Detroit Diesel, Chevrolet, and Ford. Beyond engine diagnostics, the website lists electrical repair, brake service, suspension components, and steering systems as core competencies. This breadth allows the shop to address both minor maintenance needs and major rebuilds without referring customers to separate specialists.
Customer feedback reveals specific repair scenarios demonstrating the team's capabilities. One reviewer described breaking down while hauling a 40-foot trailer and being able to limp the vehicle to the shop lot where rapid transmission diagnostics got them back on the road. Another customer noted the shop installed aftermarket parts they had ordered separately, accommodating parts sourcing beyond what the shop stocks directly. A third review credited the technician with solving a problem that other diesel mechanics could not identify despite the customer having spent thousands attempting previous repairs.
What Customers Say
Seven of eight fully documented reviews award 5 stars, with customers specifically praising diagnostic speed and fair pricing. The sole 1-star review cited incomplete work on injectors and coolant replacement, noting residual oil and fuel in the coolant and loose components under the hood.
