ABSTRACT:
In order to minimize the number of valves and conduits and the amount of coolant must be carried in an auxiliary reservoir of an evaporative type automotive cooling system, the valve and conduit arrangement which communicates the normally closed circuit cooling system with the reservoir consists of only two conduits and two valves. When the engine is stopped the cooling circuit is allowed to fill completely with the coolant from the reservoir. When the engine is started a low temperature non-condensible matter purge operation is avoided and if the temperature rises above a target value, either coolant is pumped out of the system (if excess coolant is available therein) or high temperature vapor is vented from the bottom of the radiator in bursts to purge out the non-condensible matter.
