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 * 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 at 65.5°C [150°F] 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. 27 / 149 pages
