Chevy Duramax engines are reliable and powerful engines that were introduced in 2001. They have had problems, most of which Chevy has taken care of with updates. Some issues were found in specific years, and some in all versions. Most of the issues were with the LB7 (2001-2004) engines. RDI Power in Brooksville FL can help with Duramax engine problems that the dealers haven’t put out a recall for.
1. Fuel Issues
Common Silverado problems include trucks with the LB7, LLY (2004-2005) and certain later models and the fuel injector harness wiring. The harness rubs against the engine and causes shorted and / or broken circuits. The computer throws a code that usually shows an “open circuit” for certain injectors. The repair is repairing the wiring and insulating the harness better.
Additionally, the LB7, LLY, LBZ (2006-2007), LMM (2007-2010), and LML (2011-2016) had fuel starvation issues. Because Chevy didn’t add a low-pressure electric pump to move the fuel to the injection pump, air would get trapped in the lines. In some trucks, the culprit was a cracked fuel filter housing on the mechanical fuel pump. If you suspect your Silverado diesel problems are fuel-related, make an appointment with RDI Power in Brooksville FL to diagnose and repair the issue.
2. Glow Plug Issues
Chevy Silverado common problems in the LLY and LBZ models include glow plug failures. The glow plugs would fail because the module cycled the glow plugs too much. In most cases, these trucks were recalled. However, if you buy a used Chevy Silverado, always check if the previous owner brought the truck to the dealer to have the issue repaired under the recall. If you purchased one of these models and did not realize it was a recall, and if the recall is no longer open, a light-duty truck repair tech at RDI Power can repair the issue for you.
3. NOx Sensors
One of the issues the 2011 Chevrolet Silverado has is an issue with the NOx sensors. These sensors control the DEF in the catalyst. However, the tank heaters, DEF sensors and NOx sensors are all common failures. Because of this, Chevy gave the 2011 trucks extended warranties. RDI Power can make repairs under the warranty for you.
4. Water Pump Issues and Overheating
The Chevy Silverado LB7 and LLY had issues with overheating. GM corrected most of that issue by replacing the radiators, fans and water pumps when it manufactured the new generation of the engine in 2006. However, other issues, such as failed fan clutches and blown head gaskets, can cause overheating.
The Duramax water pumps on all models also tend to fail around 80,000 to 100,000 miles. The issue is most likely with how the water pump is manufactured rather than an actual engine problem.
