This water pump, identified by the part number 5 - 87311242 - 0 (alternatively written as 5873112420), is specifically designed for the 4HK1 engine. It is a crucial element in the engine's cooling system, ensuring efficient heat dissipation and maintaining the engine's optimal operating temperature under various working conditions.
Performance Specifications
Flow Rate
Under normal operating conditions of the 4HK1 engine, the water pump is engineered to achieve a coolant flow rate of [X] liters per minute. This flow rate is essential for effectively transporting heat away from the engine block, cylinder head, and other hot components. Whether the engine is running at idle, under light - load during normal driving, or under heavy - load such as when towing or climbing steep inclines, the consistent coolant flow helps in maintaining a stable temperature.
Pressure Generation
The water pump can generate and sustain a maximum pressure of [Y] kPa within the cooling system. This pressure is necessary to overcome the resistance present in the cooling system's hoses, pipes, and the radiator. By maintaining an appropriate pressure, the water pump ensures that the coolant reaches all the areas of the engine that require cooling, preventing hot - spots and potential engine damage due to overheating.
