1997 GMC K2500 Service and Repair Manual
This factory service and repair manual for the 1997 GMC K2500 is built around three engines: the turbocharged 6.5L diesel V8, the 7.4L gasoline V8 and the 5.7L gasoline V8. Only the diesel is force-fed, so one set of turbocharger procedures sits alongside two conventional gasoline sections. The truck came as a standard cab pickup, a cab & chassis or an extended cab pickup, and Sierra SL, Sierra SLE and Sierra SLT were the trims a buyer chose between when the truck was ordered.
