2009 GMC C5500 Topkick Service and Repair Manual

This factory service and repair manual for the 2009 GMC C5500 Topkick describes a chassis offered in four shapes — the 2-door conventional cab and chassis, the crew cab and chassis, a cutaway and a motorhome cutaway — across six trim codes. Two engines are listed: the turbocharged 6.6L overhead-valve V8 diesel of 403 cubic inches and the naturally aspirated 8.1L overhead-valve V8 gasoline engine of 496 cubic inches. Both get their own specifications and procedures, and the chassis, driveline and electrical systems around them are documented with torque values, wiring diagrams and diagnostics.
