The apparatus of claim 3, wherein the vacuum motor includes a vacuum tank for collecting the liquid extracted from the engine cooling system by the evacuation hose. 5. The apparatus of claim 4, further comprising: a supply tank for containing liquid coolant; and a supply tank pump for pumping the liquid coolant from the supply tank to the injection hose. 6. The apparatus of claim 4, wherein the injection hose terminates in an injector nozzle that connects to the injection point of the engine cooling system, and has a reduced diameter relative to a diameter of the injection hose for accelerating the liquid and gas mixture flowing there through. 7. The apparatus of claim 4, wherein the connector assembly is further connectable to the other of the one of cooling radiator and the heating radiator for simultaneously defining a second extraction point from the engine cooling system and for applying a vacuum to both the first and second evacuation points simultaneously. 8. The apparatus of claim 4, wherein the gas inlet is further connected to the pre-charge tank so that compressed gas provides force for the supplying of liquid under pressure from the precharge tank to the injection hose. 9. The apparatus of claim 8, wherein the precharge tank bypass line further comprises a gas bypass valve for adjusting a relative amount of compressed gas that bypasses the pre-charge tank and is mixed with the liquid. 10. The apparatus of claim 9, further comprising: a gas reserve tank connected to the gas inlet, for storing and supplying compressed gas to the precharge tank and the precharge tank bypass line. 11. The apparatus of claim 9, further comprising: a recycle line connected between the vacuum tank and the pre-charge tank; and a recycle pump for selectively pumping liquid,through the recycle line from the vacuum tank to the pre-charge tank. 12. The apparatus of claim 11, further comprising: a filter bypass line connected in parallel to at least part of the recycle line; at least one filter attached to the filter bypass line for filtering any liquid flowing therethrough; and a filter bypass valve for selectively directing liquid flowing in the recycle line to flow through the filter bypass line and the at least one filter. 13. The apparatus of claim 12, further comprising: a gas control valve connected to the gas inlet for selectively cutting off the supply of compressed gas to the precharge tank and the precharge tank bypass line. 14. The apparatus of claim 12, further comprising: a controller for controlling the vacuum motor, the recycle pump, the filter bypass valve and the gas control valve. 15. The apparatus of claim 14, wherein the precharge tank includes a plurality of sensors to detect the level of liquid in the precharge tank, and wherein the controller is responsive to the plurality of sensors to deactivate the recycle pump when the detected liquid level reaches a predetermined value. 16. The apparatus of claim 14, further comprising: a first pressure sensor for measuring the pressure of the liquid and gas mixture in the injection hose, wherein the controller is responsive to the first pressure sensor to deactivate at least one of the vacuum motor, the recycle pump, the filter bypass valve and the gas control valve upon the measurement of pressure that exceeds a predetermined value. 17. The apparatus of claim 16, further comprising: a second pressure sensor atta
