A coolant flange in a car acts as a connecting point for various cooling system components. It is typically made of metal or plastic and is located near the engine block. The primary function of the coolant flange is to allow the coolant to flow between the engine, radiator, heater core, and other cooling system parts.

Working of a Coolant Flange

The coolant flange features multiple ports or connections to accommodate different hoses and pipes. These connections enable the transfer of coolant to different areas of the engine and cooling system. For example, the coolant flange may have ports for the upper and lower radiator hoses, heater hoses, and coolant temperature sensor.

By providing a central point for coolant circulation, the coolant flange ensures efficient cooling of the engine and prevents overheating. It allows coolant to be evenly distributed throughout the system, helping to maintain optimal engine temperature. The coolant flange also allows for easy removal and replacement of hoses or components without the need to disconnect the entire cooling system. Overall, the coolant flange plays a crucial role in the proper functioning and performance of the car's cooling system.
