General Semi Truck & Diesel Repair Services

Semi trucks are built to endure long distances and heavy loads, but constant wear can lead to issues that require expert attention. At 205 Diesel Repair, we provide complete repair and maintenance solutions for both semi trucks and diesel trucks. From drivetrain concerns and cooling issues to electrical diagnostics and fuel system repairs, our technicians use advanced equipment and industry-leading techniques to keep your truck performing at its best. We understand the importance of minimizing downtime, and we work efficiently to get your rig back on the road as quickly as possible.

How Do I Know if My Aftertreatment Systems Need Attention?

Semi trucks rely heavily on EGR systems, Diesel Particulate Filters, and other aftertreatment components to stay compliant with emissions regulations. Signs like reduced engine power, poor fuel economy, frequent regeneration, or dashboard warnings indicate your systems may need service. Our diagnostic tools accurately locate the issue, allowing us to repair or clean your aftertreatment components and restore optimal performance.

What Happens if My Cylinder Heads Blow?

A failing cylinder head can lead to overheating, poor acceleration, or white smoke from the exhaust—issues that no semi truck can afford on long hauls. Our team can diagnose, repair, or replace damaged cylinder heads with precision, helping your engine operate smoothly and preventing further internal damage.

Why Is a Functional Fuel Injector Important?

Fuel injectors play a key role in the efficiency and power of both semi trucks and diesel trucks. When injectors become clogged or fail, you may notice reduced fuel mileage, rough idling, or higher emissions. We specialize in fuel injector cleaning, calibration, and replacement to keep your engine firing cleanly and efficiently.
