Troubleshooting & Repairing Duramax Problems
Even the best Duramax diesel engines can develop issues over time. At DMR Diesel Repair, we specialize in diagnosing and fixing:
Early LB7 Duramax engines (2001-2004) are known for premature fuel injector failures, leading to rough idling, excessive smoke, and poor fuel economy.
Higher cylinder pressures in LMM (2007-2010) and LML (2011-2016) models can cause head gasket leaks, leading to overheating and coolant loss.
The CP4 fuel pump in LML Duramax engines (2011-2016) is prone to premature failure, often resulting in catastrophic fuel system damage.
Glow plugs in LLY (2004.5-2005), LBZ (2006-2007), and LMM (2007-2010) engines can fail, making cold starts difficult.
The variable geometry turbocharger (VGT) can suffer from carbon buildup, causing low boost pressure, sluggish acceleration, or excessive smoke.
The EGR (Exhaust Gas Recirculation) system can become clogged with soot and carbon, leading to reduced power and overheating.
Duramax engines often experience water pump failures, causing coolant leaks and overheating if not replaced in time.
The oil cooler seals can fail, leading to oil/coolant cross-contamination and potential engine damage.
Newer Duramax engines (2011+ LML and L5P models) feature a Diesel Exhaust Fluid (DEF) system that can suffer from sensor failures and DEF crystallization, triggering check engine lights and reduced power mode.
Duramax engines can develop oil leaks from the rear main seal, valve covers, and oil cooler lines.
Our advanced diagnostic tools and repair techniques allow us to quickly pinpoint issues and restore your Duramax engine’s power and reliability.
