Abstract
The invention comprises a method and apparatus for flushing debris from a liquid circulation system such as the cooling system of a water-cooled vehicle. The apparatus includes an inlet conduit for flushing liquid, a series of branch conduits connected to points on the circulation system, a drainage conduit for used water, and a valve or series of valves settable between various positions dictating different flow paths for the flushing liquid through the conduits and the circulation system.
Claims6
A method of flushing debris from a motor vehicle cooling system composed of three units in the form of a watercooled engine, a radiator, and a heater, the method including the steps of connecting each of the cooling system units by means of a conduit to a source of flushing liquid under pressure, and selectively opening and closing the three conduits and connecting one of them to a drain outlet so that flushing liquid passes in a sequence of phases through the cooling system to the drain outlet, the sequence comprising three phases in each of which the flushing liquid enters the cooling system through one of the conduits and leaves through another conduit, the flow path of the flushing liquid through the cooling system in each phase passing through at least two of the cooling system units and being different from the flow path followed in the other two phases.
