An exemplary cooling system includes, among other things, a first pump to supply coolant to a cylinder head or cylinder block of an engine, a second pump to supply coolant to a cylinder block or cylinder head of the engine. A control unit governs the first pump and second pump. Fluid return channels recirculate coolant to the pumps. The first and second pumps are arranged to backflow coolant through the engine.

1. A cooling system for an internal combustion engine, the internal combustion engine having a cylinder block and a plurality of cylinder heads, the system comprising: a first pump in fluid communication with the engine, the first pump being an electric pump;a second pump in fluid communication with the engine, the second pump being an electric pump;a control unit that governs the first and second pumps; andat least one fluid return channels configured to recirculate coolant to at least one of the first and second pumps,wherein the first pump is configured to supply coolant to a first cylinder head,wherein the second pump is configured to supply coolant to a second cylinder head,wherein the first and second pumps are arranged to backflow coolant through the engine. 2. The system of claim 1, wherein the control unit governs at least one of the first pump and second pump as a function of engine operation. 3. The system of claim 2, wherein the control unit governs at least one of the first pump and second pump as a function of engine flow demand. 4. The system of claim 2, wherein the control unit governs at least one of the first pump and second pump as a function of engine pressure demand. 5. The system of claim 2, wherein the control unit governs at least one of the first pump and second pump as a function of engine speed. 6. The system of claim 1, wherein the control unit governs at least one of the first pump and second pump as a function of coolant temperature. 7. The system of claim 1, wherein the control unit governs at least one of the first pump and second pump as a function of a transmission speed. 8. The system of claim 1, wherein the first and second pump are arranged in parallel. 9. The system of claim 8, further comprising a third pump arranged in series with at least one of the first and second pump. 10. The system of claim 1, wherein the cooling system includes a third pump to supply coolant to at least one of the first cylinder head or the second cylinder head. 11. The system of claim 10, wherein the cooling system includes at least one pump for each cylinder in the plurality of cylinders, each pump configured to supply coolant to a respective cylinder. 12. The system of claim 1, wherein the flow from the first and second cylinder heads flows directly to the cylinder block, the first and second pumps are arranged to backflow coolant through the cylinder block by directing the coolant upward from a base of the cylinder block to an upper portion of the cylinder block. 13. The system of claim 1, wherein the first and second pumps are arranged to backflow coolant through the engine such that the flow moves opposite a natural direction of flow through the engine. 14. A cooling system comprising: a first pump to supply coolant to a cylinder block of an engine;a second pump to supply coolant to the cylinder block of the engine;a control unit that governs the first pump and second pump; andat least one fluid return channel to recirculate coolant to the first and second pumps, wherein the first and second pumps are arranged to backflow coolant through the engine. 15. The cooling system of claim 14, wherein the first and second pump are arranged in parallel. 16. The cooling system of claim 14, further comprising a third pump arranged in series with at least one of the first and second pump. 17. The cooling system of claim 14, wherein the engine comprises a plurality of cylinders and wherein the cooling system includes a third pump to supply coolant to at least one of the cylinders. 18. The cooling system of claim 17, wherein the cooling system includes at least one pump for each cylinder in the plurality of cylinders, each pump configured to supply coolant to a respective cylinder. 19. The system of claim 14, wherein the flow from the cylinder block flows directly to the a cylinder head of the engine, the first and second pumps are arranged to backflow coolant through the cylinder head, the cylinder block, or both by directing the coolant to flow opposite a natural direction of flow. 20. A cooling method, comprising: supplying coolant to at least one of a cylinder head or a cylinder block of an engine using a first pump;supplying coolant to the one of the cylinder head or the cylinder block of the engine using a second pump;governing the first and second pumps using a control unit;recirculating coolant to the first and second pumps; andbackflowing coolant through the engine using the first and second pumps.
