1998 GMC K2500 Service and Repair Manual
This factory service and repair manual for the 1998 GMC K2500 lists four engines: gasoline V8s of 5.0, 5.7 and 7.4 liters and a turbocharged 6.5L diesel V8. Three body styles are covered, the standard cab pickup, the cab & chassis and the extended cab pickup, and three trims, Sierra SL, Sierra SLE and Sierra SLT. The practical consequence for a shop is that one book carries both the gasoline tune-up figures and the diesel injection and turbocharger specifications for the same chassis.
