2006 Chevrolet Suburban 2500 Service and Repair Manual

This factory service and repair manual for the 2006 Chevrolet Suburban 2500 lists two engines, one body and two trims: a 6.0L overhead-valve V8 of 364 cubic inches and an 8.1L overhead-valve V8 of 496 cubic inches, both naturally aspirated and both gasoline, in a four-door sport utility sold as LS or LT. On a truck this consistent from year to year, the value of factory material is depth rather than breadth, and that is what the torque values, wiring diagrams and system-by-system diagnostic routines here provide.

Known issues on the 2006 Suburban 2500. One recall stands on the federal record for this year, and it is a labeling failure with mechanical consequences: the tire and loading information label was printed with an inaccurate capacity weight, which can lead an owner to overload the truck or set tire pressures wrongly and bring on a tire failure. Owner complaints number 56 and spread thinly, 11 against the electrical system, nine against the service brakes and nine against the structure. Wiring diagrams, brake specifications and body procedures in this manual address the first two of those directly.
