After looking closer to the front of the vehicle. I do not think a cold front will harm it in any way, Underneath the grill is open and will allow sufficient airflow should the electric fan need to operate. The main advantage I see to the cold front is to prevent the frigid air from entering at full force on those sub-zero days. Also to keep the the engine from cooling so quickly. That little 4 banger does not retain heat like my F250 6.0 diesel.
