1991 Chevrolet V2500 Suburban Service and Repair Manual

This factory service and repair manual for the 1991 Chevrolet V2500 Suburban comes down to two engines and two trims: a naturally aspirated 6.2L OHV diesel V8 of 379 cubic inches or a naturally aspirated 5.7L OHV gasoline V8 of 350 cubic inches, in a four-door sport utility badged Scottsdale or Silverado. The narrower the mechanical spread, the more direct the manual becomes — a technician turns to the section for the engine in front of him and finds the clearances, torque values and diagnostic steps for it.
