1987 Chevrolet S10 Blazer Service and Repair Manual
This factory service and repair manual for the 1987 Chevrolet S10 Blazer covers four trims — Base, High Country, Sport and Tahoe — on a single two-door sport utility body. Two naturally aspirated gasoline engines are documented: the 2.5-liter overhead-valve four of 151 cubic inches and the 2.8-liter overhead-valve V6 of 173. Trim content changes what is wired and trimmed inside the vehicle rather than what turns the wheels, so the electrical diagrams carry more of the variation than the engine chapters do.

Known issues on the 1987 S10 Blazer. Five recalls appear on the federal record for the 1987 Blazer, and two of them threaten steering control. The intermediate shaft can loosen where it couples to the steering gear until the pinch bolt wears through the splines and the shaft can separate; separately, inner tie rod nuts left improperly torqued and uncrimped can come off and let the tie rod disengage. Three more cover replacement lamps without amber side reflectors. Thirty complaints cluster on seat belts, the fuel system and brakes, each with its own diagnostic and torque specifications here.
