At temperatures below 0°C [32°F], operate the engine at moderate speeds for 5 minutes before full loads are applied. Winterfronts Winterfronts can be used on a vehicle equipped with charge air cooling (CAC), but must be designed to partially cover the frontal area of the cooling system. A minimum of 120 square inches (11 in x 11 in) of frontal area must be left open to air flow for the CAC to function correctly.
Shutters Installations of CAC engines with shutters also requires an intake manifold air temperature switch to open the shutters to prevent excessive intake manifold temperatures. This prevents engine damage due to high intake manifold temperatures as a result of blocked air flow across the CAC. 24 / 167 pages Starting Aid Requirements U se the following chart as a reference for required cold weather starting aids:
