1991 Chevrolet V1500 Suburban Service and Repair Manual

This factory service and repair manual for the 1991 Chevrolet V1500 Suburban documents Scottsdale and Silverado versions of the four-door sport utility, each available with one of two naturally aspirated V8s: the 6.2L OHV diesel of 379 cubic inches or the 5.7L OHV gasoline unit of 350 cubic inches.
