This factory service and repair manual for the 2003 Chevrolet Suburban 2500 documents a two-engine, two-trim year: the 6.0L overhead-valve V8 of 364 cubic inches and the 8.1L overhead-valve V8 of 496 cubic inches, both naturally aspirated on gasoline, in LS and LT versions of the four-door sport utility. A technician needs to know which V8 is in front of him before opening the specifications, because the two displacements are tabled separately throughout, while the driveline, chassis and body material applies to the truck whichever engine it left the plant with.
Engines covered
- 6.0L V8 (364 cu in) — OHV, naturally aspirated, gasoline
- 8.1L V8 (496 cu in) — OHV, naturally aspirated, gasoline
Body styles covered
- 4-door sport utility
Trims covered
