2002 GMC C3500HD Service and Repair Manual
This factory service and repair manual for the 2002 GMC C3500HD applies to both listed chassis forms — the two-door conventional cab and chassis and the four-door crew cab and chassis — in Base trim, and to the two engines available in them, the turbocharged 6.5L diesel V8 and the naturally aspirated 8.1L gasoline V8. A shop working on one of these usually meets it with a body already fitted, so the manual's system-by-system procedures, specifications, torque values, wiring diagrams and diagnostics are the reference for what lies underneath.

Known issues on the 2002 C3500HD. No recalls were issued for this model year and NHTSA holds no owner complaints, so the record is clean. What remains is the ordinary business of keeping a heavy truck working, and that is where the manual is used: engine service specifications for the diesel and the 8.1L gasoline V8, transmission and axle repair, brake system service, steering and suspension work, frame and cab procedures, and the wiring diagrams and diagnostic routines for the circuits that tie them together.
