Common Duramax Diesel Problems
The GM Duramax has proved to be a relatively reliable and durable engine. Various versions of the engine and all generations of the Duramax are based on the same design. Each generation is an evolution of the previous model, with improvements and modifications.
Like any automotive part the Duramax engine and Allison transmission have some common problems. Some of these issues can be prevented or corrected with modifications, while others may be avoided by understanding and avoiding the root cause.
Duramax Fuel Starvation Due To Air in the Fuel Lines
Problem: Duramax diesel is susceptible to fuel starvation and air in the fuel lines. This problem results from the fuel filter housing design and the because the Duramax does not use a lift pump.
The high pressure fuel injection pump sucks fuel from the tank. When the fuel filter housing develops a small crack or fuel filter housing seal or water-in-fuel sensor seal leaks air enters the fuel system. Air can also enter the fuel system when the fuel filter is changed. It can be difficult to purge air from the fuel system and prime the fuel system.
Repair: Find source of fuel systemair leak. Fuel filter housing replacement; Fuel filter seal replacement; Fuel water sensor seal replacement. Purge air from fuel system.
Duramax Water Pump Failure
Problem: Water pump failure for Duramax engine are common at 80,000 - 100,000 mile range.
Repair: Duramax water pump replacement.
Problem: Duramax diesel overheating issues depend on the vehicle usage, but are more common with the Duramax than other engines. Duramax overheating commonly occurs while towing or hauling heavy loads. Duramax overheating can occur due to fan clutch failure, clogged radiator with older vehicles. Water pump failure, and resulting coolant loss, can also cause overheating. In rare cases Duramax cylinder head leak can cause overheating.
Repair: Identify cause of overheating. Duramax radiator replacement (we recommend a larger radiator); Duramax fan clutch replacement; Water pump replacement; Duramax cylinder head gasket replacement.
Duramax Injector Failure
Problem: Duramax premature injector failure. Mostly due to poor injector design but GM Duramax injectors are sensitive to contamination and may fail prematurely if regular fuel filter change maintenance is not performed. Fuel quality is a major factor in fuel filter life.
Repair: fuel injector replacement.
Duramax Injector Harness Failure
Problem: Duramax injector wiring harness chafe and break over time. Can cause a number of issues including a no-start, rough running, and lack of power problems. Associated Check Engine Light fault codes usually reveal which injectors are affected.
Repair: Wiring harness replacment or repair.
Duramax Glow Plug Failure
Problem: Duramax glow plug failure is a problem with early Duramax models. Glow plug module would over cycle the glow plugs causing the glow plug to fail. Catastrophic engine damage can occur. New glow plug modules have been reprogrammed to eliminate this risk.
Repair: Duramax glow plug module replacement; Engine repair as necessary.
Duramax Intercooler Boot Failure
Problem: Oil from Duramax PCV design rapidly degrade intercooler boots and cause boot failure.
Repair: Duramax intercooler boot replacement; Duramax PCV modification to aftermarket oil catch can.
Duramax Allison Transmission Limp Mode
Problem: Duramax Allison transmission goes into limp mode. This feature is a safeguard against catastrophic transmission failure and should not be ignored. In some cases such as a heavy load, towing, down shifting to pass, etc, and is especially common in performance tuned trucks can cause enough transmission slippage to trigger limp mode.
While in limp mode, the transmission will lock in 3rd gear, the torque converter will remain unlocked, and the transmission will not be able to operate in reverse. If your transmission experienced limp mode it may be on the verge of needing a rebuild in the near future.
Repair: Diagnose cause for going into Duramax transmission limp mode. Duramax transmission rebuild; Modify Duramax transmission for high performance or heavy load usage.
Duramax LML DEF/SCR System Problems
Problem: Duramax LML DEF SCR system is a most sophisticated and complex emission control system and suffers from many problems. Most common problem is Duramax NOx sensor failure. Additional problems include DEF level sensors, DEF pumps, and DEF tank heaters. Some models may be covered by an extended GM warranty.
Repair: Duramax NOx sensor replacement; Duramax DEF level sensor replacement; Duramax DEF pump replacement, and Duramax DEF tank heater replacement.
