The 2001-2004 LB7 Duramax introduced GM diesel owners to the Duramax platform, and injector problems quickly became the repair most people associate with these trucks. Even well-kept LB7s eventually deal with injectors, fuel system wear, turbo age, cooling issues, and front-end drivetrain repairs.
Fuel system components, turbochargers, injectors, CP3 pumps, cooling parts, exhaust components, and drivetrain parts are some of the biggest repair and upgrade areas on 2001-2004 LB7 trucks. If injectors are already coming out, many owners handle related seals, lines, and fuel system parts at the same time because labor overlap adds up quickly.
