Abstract
A motor vehicle equipped with a liquid-cooled internal combustion engine. A radiator is provided, the same having first and second regions which themselves have aligned edges that form an edge of the radiator. Conduits are provided for allowing the flow of coolant through the two regions of the radiator in opposite directions. A coolant chamber extends along the edge of the radiator, this coolant chamber being divided into first and second sub-chambers by a partition which extends transversely to the edge and which defines the demarcation between the first and second regions of the radiator. The first and second sub-chambers of the coolant chamber communicate with the first and second regions of the radiator, respectively. A thermostatic valve arrangement is provided which allows the flow of coolant from the first sub-chamber to the second sub-chamber, and hence through both the first and second radiator regions, only when the temperature of the coolant is above a predetermined temperature.
