<p>A valve assembly directs engine coolant either through a bypass port for return to an engine or through a radiator port for direction to a radiator for cooling. The valve assembly includes a valve pivotable over a larger radiator hole and a smaller bypass hole. When the valve is in the live position, the radiator hole is covered by the valve and coolant flows through the bypass hole for return to the engine. When the valve pivots towards the dead position, the bypass hole is covered, exposing the radiator hole. The coolant flows through the radiator hole to the radiator for cooling. The position of the valve depends on a value detected by a temperature sensor.</p> |
