1998 GMC K2500 Suburban Service and Repair Manual
This factory service and repair manual for the 1998 GMC K2500 Suburban takes the four-door sport utility in Base, SLE and SLT trim, with the turbocharged 6.5L diesel V8, the 7.4L gasoline V8 and the 5.7L gasoline V8 as the engine choices. Two of the three are naturally aspirated; only the diesel carries a turbocharger, and its specifications, torque values and diagnostic routines are set out apart from the gasoline engines' so the right figures are easy to isolate.
