Abstract: A fluid flushing machine for a vehicle engine component uses a pre-heated cleaner/fluid to increase the effectiveness of the cleaning procedure and reduce the time needed to clean the component. The invention is designed to clean air charged coolers, EGR valves, EGR coolers, and other components that over time have become contaminated with carbon build up, oil, and debris. The machine of the present invention has the option to direct heated cleaning fluid through the vehicle engine's cooling system to remove carbon build up, oil, and debris in the vehicle's EGR valve and cooler component. The machine of the present invention is adapted to perform the operation in an engine-off condition by incorporating an integrated or external electronic device to open the vehicle's EGR valve to allow the cleaning fluid to flow through the engine while it is turned off.

Abstract: A vehicle fluid exchange machine is disclosed that allows the technician to control the flow into the vehicle or stand-alone cooling or hydraulic system either manually or automatically based on a safe working pressure for the vehicle. If the vehicle's cooling system can handle a higher pressure for example, the technician may adjust the machine's flow to a flow rate consistent with the higher pressure rating while monitoring the pressure across the system. The default setting for the air injection process is automatic, but can also be switched to manual by the technician.
