2014 Mercedes-Benz HDX Service and Repair Manual

This factory service and repair manual for the 2014 Mercedes-Benz HDX covers a straight truck chassis with a low tilt cab, the only body style covered, in the Chasis de Autobus CNG trim. Its engine is an 8.9L inline-six with a single overhead camshaft and a turbocharger, set up to run on LPG (propane). A heavy six-cylinder on gaseous fuel changes the fuel system work considerably, and the manual addresses that engine together with the chassis, cab and electrical systems of this truck.

Known issues on the 2014 HDX. Service on this truck chassis turns on two things: a turbocharged 8.9L six fed by propane, and running gear built to carry heavy loads. The manual answers both with procedures and specifications for the engine, its turbocharger and its gaseous fuel system, torque values for engine and chassis fasteners, brake and steering service steps, and wiring diagrams with diagnostics for the low tilt cab and chassis electrical circuits.
