General Diesel Repair in Sioux Falls, SD & Surrounding Area

About Our Diesel Repair Services

Matt’s Repair provides heavy-duty diesel repair for heavy-duty, medium-duty, and light-duty trucks, as well as trailers, RVs, and fleet vehicles. Diesel engines and supporting systems are built for durability, but wear, heat, and heavy loads eventually take their toll.

Our general diesel repair services include:

• Complete engine diagnostics
• Fuel system inspection and repair
• Turbocharger inspection and replacement
• Cooling system repairs
• Electrical system diagnostics
• Driveline and axle repairs
• Brake and suspension repairs
• Emissions system service

Modern diesel trucks rely on high-pressure fuel systems, advanced electronics, and emissions components to operate efficiently. Issues with injectors, turbochargers, sensors, or airflow can reduce performance and fuel economy. Early diagnosis helps prevent further internal damage and costly breakdowns.

Signs Your Diesel Truck Needs Professional Repair

Diesel problems often become more noticeable as components continue to wear or operating conditions place additional strain on the truck. Changes in performance should be inspected rather than relying on repeated resets or temporary fixes.

Common signs include:

• Loss of Power: Slower acceleration or difficulty maintaining power under load can indicate a developing mechanical or fuel-delivery problem.
• Hard Starting: Extended cranking or inconsistent starting may point to fuel, air, electrical, or mechanical concerns.
• Unusual Diesel Smoke: Changes in exhaust smoke can indicate improper combustion, airflow problems, fuel concerns, or other operating issues.
• New Noises or Vibration: Knocking, rattling, grinding, or unexpected vibration can indicate worn or damaged components.
• Fluid Leaks: Oil, coolant, fuel, or other fluid loss should be inspected to determine the source before levels become unsafe.
• Changes in Fuel Economy: A noticeable increase in fuel consumption can accompany mechanical problems or inefficient engine operation.
• Repeated Warning Lights: Warning lights that return after being cleared indicate an underlying condition that still needs attention.
