Shutters are designed to control air-flow across the radiator. If the shutters fail to open when needed, the engine can run hot. Failure of the shutters to close can result in too much air-flow and the engine running cold.

NOTE: Make sure that the air temperature sensor is functioning correctly. Check the air-operated shutter controls. Check for air leaks. Refer to the equipment manufacturer’s service manual.

Winterfronts can be used on a charge air cooled engine, but must be designed to cover part of the frontal area of the cooling system. A minimum of 77419 sq mm [120 sq in] of charge air cooled frontal area must be left open to air-flow.
