1989 Chevrolet S10 Blazer Service and Repair Manual
This factory service and repair manual for the 1989 Chevrolet S10 Blazer covers a two-door sport utility built in Base, High Country and Sport form, with two V6 engines to document: the 2.8-liter overhead-valve unit of 173 cubic inches and the 4.3-liter of 262, both naturally aspirated on gasoline.
