1990 Chevrolet V1500 Suburban Service and Repair Manual

This factory service and repair manual for the 1990 Chevrolet V1500 Suburban is written for a truck that could arrive with either of two large pushrod V8s — a 350-cubic-inch 5.7L on gasoline or a 379-cubic-inch 6.2L on diesel, both naturally aspirated — in Scottsdale or Silverado trim on the four-door sport utility body. Which one is under the hood determines a great deal, from starting system components to service intervals, and the manual is arranged so the two never have to be read against each other.
