1998 GMC C2500 Suburban Service and Repair Manual

This factory service and repair manual for the 1998 GMC C2500 Suburban covers three engines across one body style and three trims. The engines are the turbocharged 6.5L diesel V8 and the naturally aspirated 5.7L and 7.4L gasoline V8s; the body is the four-door sport utility; the trims are Base, SLE and SLT. Because the same chassis carries all of them, the manual can spend its detail on the differences — engine specifications, torque values and diagnostics that change with the powerplant — while treating the shared systems once and thoroughly.
