Common Duramax Diesel Repairs
Even with proper maintenance, Duramax engines can develop issues over time. Here are some of the most common Duramax diesel repairs we handle at our Cumming, GA shop:
Fuel System Repairs
Duramax fuel injectors are prone to wear and carbon buildup, leading to misfires, rough idling, and poor fuel economy. We offer fuel injector cleaning and replacement to restore your truck’s performance.
Turbocharger Repairs
A failing turbocharger can cause loss of power, excessive smoke, and poor acceleration. If you suspect turbo issues, our diesel mechanics can diagnose and repair or replace the unit.
EGR & DPF Issues
To meet emissions regulations, Duramax engines use an Exhaust Gas Recirculation (EGR) system and a Diesel Particulate Filter (DPF). Over time, these systems can clog with carbon buildup, leading to performance problems and warning lights. Regular cleaning or replacement ensures proper function.
Cooling System Repairs
If your Duramax engine is overheating, it could be due to low coolant, a failing water pump, or a clogged radiator. We provide complete cooling system repairs, including coolant flushes, thermostat replacements, and radiator services.
Transmission & Drivetrain Repairs
If your Duramax-powered truck is having trouble shifting gears or experiencing transmission slip, our team can diagnose and repair the issue before it turns into a major problem.
No matter what’s wrong with your Duramax engine, our diesel mechanics have the knowledge and tools to fix it.
