1986 Chevrolet K10 Suburban Service and Repair Manual

This factory service and repair manual for the 1986 Chevrolet K10 Suburban covers three naturally aspirated overhead-valve engines under one four-door sport utility body: a 5.0L V8 of 305 cubic inches, a 5.7L V8 of 350 and a 6.2L diesel V8 of 379. Custom, Scottsdale and Silverado are the trims. The two gasoline V8s differ enough in displacement to need separate specifications, and the diesel is separate again, with its own injection procedures and diagnostic sequences.
