Abstract
Conventionally, cooling systems are drained and flushed out with a gravity flow of water added through the radiator cup. The present device permits power back scrubbing and flushing through the heater core, through the engine and then through the radiator core thus removing far more scale, rust and sludge than the usual system. It can incorporate a pressure test and then can add the correct amount of antifreeze to the water within the system.
