Abstract
A cooling system for a combustion engine (1) includes a pilot line (12) which has an inlet (12a) to receive coolant from a line (3) of the cooling system and a thermostat (6) a sensing element (6b) for monitoring the temperature of the coolant in the pilot line (12) and a valve (6a). A thermal device (13, 26, 31) in contact with the coolant in the pilot line (12) at a location upstream of the sensing element (6b). A control unit (15) estimates when it is appropriate to alter the coolant's operating temperature in the cooling system and, at such times, activates the thermal device (13, 26, 31) so that it warms or cools the coolant in the pilot line (12).
