Known issues on the 2012 Gran Viale. A 12-liter turbocharged diesel working in bus service accumulates hours and heat quickly, which puts injection, turbocharger, cooling and lubrication at the top of the maintenance list. The manual pairs those engine systems with chassis, driveline and electrical coverage for the cab-forward bus, giving procedures, specifications, torque values, wiring diagrams and diagnostics.
