1998 GMC K1500 Service and Repair Manual
This factory service and repair manual for the 1998 GMC K1500 documents a pickup available in three cab styles, the 2-door standard cab, the 3-door extended cab and the 2-door extended cab, and in four trims from Sierra SL through Sierra SLE and Sierra SLT to Sierra Special. Four engines serve them: the 5.0L and 5.7L gasoline V8s, the 4.3L gasoline V6 and the turbocharged 6.5L diesel V8.

Known issues on the 1998 K1500. No recalls and no owner complaints are logged with NHTSA against this model year, so the federal record here is clean. What remains is the manual itself, which works through engine mechanical and fuel system procedures for the gasoline V8s, the V6 and the turbocharged diesel, then continues into transmission and axle overhaul, steering and suspension, the brake and antilock systems, climate control and the body, each with its own specifications, torque values, wiring diagrams and diagnostic charts.
