Abstract
Cooling system, particularly for vehicle engines, includes a coolant circulation pump (21) and a cooling fan (20) typically coacting with a radiator (14) both driven by a common variable speed motor (18) whereby both the pump and fan can be operated at lower and higher speeds in response to the sensed temperature levels of the coolant.
