1994 Chevrolet S10 Blazer Service and Repair Manual

This factory service and repair manual for the 1994 Chevrolet S10 Blazer lists five trims — Base, LT, Nevada, Tahoe and Tahoe LT — built as four-door and two-door sport utilities. Power comes from one of two naturally aspirated overhead-valve V6 engines, a 3.1-liter or the 4.3-liter of 262 cubic inches. The trim count matters most in the interior and electrical chapters, where equipment varies; the engine, driveline and chassis procedures apply across the range with specifications given per engine.
