Selecting the Right GM 6.6L Duramax Fuel Injector in Las Vegas

Posted on

General Motors used several different fuel injectors in its 6.6-liter engines made between 2004 and 2010. With a variety of options, choosing the correct one can be tricky. If you need a diesel fuel injector in Las Vegas, here are some tips to help you find the right one for your truck or van:

Don’t Rely on Appearance or Model Year

Choose the Right Fuel Injector with These Tips

When choosing a replacement fuel injector, you can’t rely on either the appearance or model year. The variations between the different injectors are minute, and it’s not always possible to tell which injectors match. In some cases, the only difference is the connector that plugs into your vehicle’s engine. Of course, having a connector that won’t connect makes installation impossible.

Model year is helpful, but alone it won’t tell you exactly which fuel injector your vehicle needs. There have been a few model years (e.g. 2007 and 2010) in which multiple fuel injectors were used.

Use Your Vehicle’s VIN Number

Finding the right fuel injector requires identifying exactly what engine your vehicle has, and that’s done with the VIN number. Specifically, you need the 8th and 10th characters in the VIN. The 8th character identifies the engine regular production option (RPO) code, and the 10th shows the model year.

Your vehicle may have any of three different engine RPO codes. The following list uses the digit in the 8th place of the VIN:

  • 2004.5 to 2005 trucks with a “2” have an LLY engine.
  • 2006 pickup trucks with a “2” have an LLY engine.
  • 2006 to 2007 pickup trucks with a “D” have an LBZ engine.
  • 2006 to 2007 G-Series vans and C-Series trucks with a “2” have an LLY engine.
  • 2007 to 2009 C-Series trucks with a “9” have an LMM engine.
  • 2007 to 2010 pickups and G-Series vans with a “6” have an LMM engine.
  • 2010.5 to 2016 G-Series vans and Cab Chassis trucks with an “L” have an LGH engine.
