2013 GMC Savana 2500 Service and Repair Manual

This factory service and repair manual for the 2013 GMC Savana 2500 sets three engines against a broad catalog. The turbocharged 6.6L V8 diesel, the naturally aspirated 4.8L flex-fuel V8 and the 6.0L V8 built for CNG or flex-fuel each carry their own specifications and torque values, while five trims, Base through SLE, and five body arrangements covering 3-door and 4-door cargo vans plus standard passenger vans in both door counts account for the differences in wiring and equipment a technician meets before the mechanical work begins.

Known issues on the 2013 Savana 2500. Two owner complaints are logged with NHTSA for this model year, both about tires. On a three-quarter-ton van that heading usually leads back to load and inflation figures, wheel fastener torque and the condition of the suspension and steering that wears a tire unevenly. Wheel and tire service procedures, suspension and alignment specifications and the torque values for hub and wheel fasteners are all given here, along with the diagnostic steps for the chassis systems sitting behind them.
