5.0 OPERATING ENVIRONMENT
5.1 ROADWAY GRADES, SURFACES AND HAZARDS
The careful selection of 4.3L V6 90 Degree Engine and Transmission in accordance with the proper
installation to the vehicle will assure the operation of the engine in a very wide range of roadway
grades, surfaces, hazard and Off Road conditions.
Altitude: The engine is designed to function at altitudes from 200ft (61M) below sea level to 14500ft
(4420M) above sea level.
Gradability: The engine is designed to function at grades -16<0< 16% GM Application engineering
will support the customer with applications out of this range.

5.2 CRITICAL COMPONENT TEMPERATURE LIMITS
The following table 5.2 shows Critical Component Temperature Limits as a reference value for
different components. The GM application will verify these values for each specific application. All
engine non-metallic components not listed in the table will withstand a minimum underhood
temperature of 121 Degree Celsius.
