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 attached to the injector nozzle for measuring a pressure of the liquid and gas mixture at the injection point of the coolant circulation system, wherein the controller is responsive to the second 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. 18. The apparatus of claim 14, wherein the controller: activates the recycle pump for pumping a predetermined amount of liquid from the vacuum tank to the precharge tank; and then deactivates the recycle pump; and then activates the gas control valve for forcing the liquid out of the precharge tank, for mixing the forced liquid from the precharge tank with the compressed gas, and for forcing the liquid and gas mixture in to injection hose and into the engine cooling system, and activates the vacuum pump to evacuate the;liquid and gas mixture from the engine cooling system, through the evacuation hose, and into the vacuum tank; and then deactivates the gas control valve and the vacuum pump; wherein said recycle pump activation and deactivation steps, and said gas control valve activation and deactivation steps and said vacuum pump activation and deactivation steps, are repeated a plurality of times. 19. A method of flushing contaminants from an internal combustion engine cooling system that includes a cooling radiator and a heating radiator both connected to an engine block with liquid coolant lines, and points of injection and extraction, the method comprising the steps of: mixing a liquid with a gas to create a liquid/gas mixture; injecting the liquid/gas mixture into an injection point of the engine cooling system under pressure; applying a vacuum to an extraction point of the engine cooling system to evacuate the liquid/gas mixture through the extraction point. 20. A The method of claim 19, wherein the injecting step and applying step are performed simultaneously to create a high speed of flow of the liquid/gas mixture through the engine cooling system. 21. The method of claim 20, wherein the injecting step is performed to the engine block, and the applying step is performed to the cooling radiator. 22. The method of claim 20, wherein the engine cooling system has a plurality of extraction points, and the applying step is performed at the plurality of extraction points simultaneously. 23. The method of claim 22, wherein the injecting step is performed to the engine block, and the applying step is performed to the cooling radiator and the heating radiator simultaneously. 24. The method of claim 20, further comprising the step of: evacuating liquid coolant from the engine cooling system before the injecting and applying steps by injecting a gas into the injection point of the engine cooling system under pressure while simultaneously applying a vacuum to the extraction point of the engine cooling system. 25. The method of claim 20, wherein the mixing step is performed so that the gas forms at least 25% of the liquid/gas mixture. 26.
