The Coolant Header Tank acts as a reservoir for coolant fluid, which circulates through the engine to regulate temperature. The header tank is built to store excess coolant, which expands and contracts as it heats and cools. It also ensures that the system remains properly pressurized, enabling the efficient flow of coolant through the radiator, hoses, and engine block.Attributes:• Stores and regulates coolant fluid for engine temperature control.• Prevents coolant spillage with a pressure-sealed plug.• Resist damage from external elements.Applications: The Coolant Header Tank is located near the engine bay, storing and circulating coolant fluid, ensuring that the engine remains within safe operating temperatures.
