A report has been received from Italy that an enemy half-tracked vehicle
has been found to be equipped with a device for heating the coolant.
A small, square-section, water tube boiler was fitted in front of the
radiator and so connected to the engine inlet and outlet pipes as to produce a
thermo-syphon circulation when heated by a stove fixed to it by means of
clamps. The report indicates that this equipment is probably standard
equipment on vehicles intended for extremely cold climates.
