1989 Chevrolet S10 Service and Repair Manual

This factory service and repair manual for the 1989 Chevrolet S10 works with two bodies, the standard cab pickup and the extended cab pickup, still offered as Base, Durango, Sport and Tahoe. Three gasoline engines are covered: the 2.5-liter overhead-valve four of 151 cubic inches, the 2.8-liter V6 of 173 and the 4.3-liter V6 of 262. Procedures, specifications, torque values, wiring diagrams and diagnostics are organized by system, so work on one engine does not mean reading past the other two.

Known issues on the 1989 S10. Five recalls are on the federal record for 1989. One covers engine cooling fan blades that break from fatigue and can throw a fragment at anyone standing at an open hood. Another covers the intermediate steering shaft working loose at the gear coupling until the splines wear and the shaft can separate. Three concern replacement lamps without amber side reflectors. Fifty-one complaints have been logged, most on seat belts, then the electrical system and tires — cooling, steering and body electrical diagnostics are all covered in this manual.
