DURAMAX DIESEL ENGINE TRUCK SERVICE

Our Hilmar drivers depend on their diesel trucks and the Duramax diesel in their Chevy or GMC pickup and our diesel technicians keep them running at peak performance by making sure we have their maintenance done on time.  The Duramax diesel engine has been consistently improved by Chevrolet / GMC over the last couple of decades and is fairly bulletproof.  This diesel engine by GM is nothing short of a spectacularly powerful, reliable power plant for its line of pickup trucks.  Since its conception, Duramax has been an innovative and respected brand, with over 1.5 million engines produced in the United States and some of the toughest engines on the market today. 

The 6.6-liter Duramax Engines is produced by DMAX, a joint venture between GM and Isuzu in Moraine, Ohio first released in late 2001 replacing the old 6.5-L Detroit built engine. GM was the first to make this jump and it gave GM an added advantage in the diesel truck market.  The Duramax Engine utilized the new Bosch Common Rail Fuel system.  The early fuel systems included an ECM (Engine Control Module), CP3 Injection pump, FICM (Fuel Injection Control Module), and injectors all of which we are familiar with and work on here at Independent Automotive Inc. .

The later version fuel system did away with the FICM and utilize a CP4 injection pump.  The Duramax Engine had some issues but they extended the warranty on the injectors to 200,000 miles due to failures that were widespread and there were a lot of diesel trucks in the shop to fix the issue.  Changing the injectors on the LB7 Duramax Engines was time-consuming since they were located under the valve cover.  The premature injector failure was actually a result of air bubbles in the fuel line.  They accumulated in the CP3 pump so when the injector went to fire, the bubble would get between the injector plunger and the injector tip.   With the bubble there, the injector plunger had no fluid damping when it comes into contact with the injector tip causing a small gap to form over time. Once that gap grows large enough fuel is allowed to flow through continuously since the rail is pressurized so high.  The computer system was unable to determine if this is happening so the check engine light would not notify the driver.  The only way to determine if this was happening was to measure the return fuel flow rate. 

Here at Independent Automotive Inc. , we keep up with issues like fuel flow rates and updates in the Duramax diesel engine so that we can provide quick diagnostics for you and answers quickly which equals more efficient and cost-effective repairs and our Duramax diesel truck drivers don't spend as much time in the shop as a result.  It is one way we are able to help our Hilmar GMC and Chevy drivers trust their diesel truck to the experts, one big issue fixed at a time!
