To confirm which engine/generation Duramax check the 8th digit in the VIN number

• If it's a 1 you have the LB7 motor
• If it's a 2 you have the LLY motor
• If it's a D you have the LBZ motor

Here's the Duramax Generations:
1st Gen 2001 - Early 2004 LB7
2nd Gen 2004.5 - 2005 LLY
3rd Gen 2006 - 2007 LLY/LBZ
4th Gen 2007.5 2010 LMM
5th Gen 2011 - Present LML

Typical Isuzu Junky! This man knows his Duramax trivia. He don't need Google for his work.
