2000 GMC C7500 Topkick Service and Repair Manual
This factory service and repair manual for the 2000 GMC C7500 Topkick concerns two engines and one chassis. The engines are the turbocharged 7.2L OHV inline-six diesel and the naturally aspirated 7.4L OHV gasoline V8. The chassis is the two-door conventional cab and chassis, sold under the C7H042 and C7H064 designations. Everything in the book is written against that combination, which keeps the engine specifications, torque values and diagnostic procedures concentrated on a pair of very different units rather than spread thin across a long lineup.
