Abstract
An apparatus includes a closed container having an inlet connected to a radiator of an engine cooling system. An outlet of the container is coupled to the suction port of a venturi that has an inlet port connected by a solenoid valve to a source of pressurized air. A controller opens the solenoid valve for a given interval whenever the engine is turned off. That action creates a negative pressure in the container which bleeds gas from the radiator. Any coolant that also is removed from the radiator is collected in the container.
