Commercial Diesel Truck Repair

Our Fullerton diesel repair shop services commercial trucks of many sizes, including work pickups, service trucks, delivery vans, box trucks, buses, semi trucks, and tractor-trailers. If your diesel truck suffers from problems such as poor acceleration, difficult starting, unusual engine noise, excessive smoke, reduced fuel economy, overheating, and illuminated warning lights, we can fix it. We inspect the engine and supporting systems, including turbos, to identify the source of the problem before recommending repairs. With professional diagnostic equipment, specialized tools, and space for extensive mechanical work, our shop is prepared to handle both routine diesel repairs and more involved commercial truck service.

Diesel Engine Diagnostics & Repair

Modern diesel engines rely on interconnected fuel, air, cooling, emissions, electrical, and computer-controlled systems. A single symptom may have several possible causes, making accurate diagnostics essential. Our technicians test components and operating data related to fuel delivery, sensors, batteries, starters, alternators, glow plugs, cooling systems, and engine performance. Available repairs may include fuel system service,  diesel fuel system repair, fuel injector diagnostics, DFP warning lights, electrical diagnosis, cooling system work, starting and charging repairs, and replacement of failed engine components. Many issues are fixed on site, while major repairs are completed at our full service Fullerton diesel shop. Give us a call to learn more or request immediate service.
