1984 Chevrolet S10 Blazer Service and Repair Manual
This factory service and repair manual for the 1984 Chevrolet S10 Blazer adds a diesel to the list: a 2.2-liter overhead-valve four of 134 cubic inches joins the 1.9-liter overhead-cam four of 119, the 2.0-liter overhead-valve four of 122 and the 2.8-liter V6 of 173. All of it goes into one body, the two-door sport utility, in Base, Sport and Tahoe trim. A diesel among gasoline engines means the fuel and engine mechanical sections carry two different sets of specifications and diagnostic steps.

Known issues on the 1984 S10 Blazer. The federal record shows four recalls for this Blazer year. Three concern replacement lamps built without amber side reflectors, which leaves the vehicle poorly lit to traffic approaching from the side. The fourth covers bucket seat back locks that may fail to function in a crash, so the seatback can move when it should stay locked. Nine complaints have been logged, three on the engine and cooling system, two each on tires and the power train — cooling, driveline and seat anchorage procedures are all covered here.
