BMW Expansion Tank Hose - Febi 45841

Product Information

The engine coolant reservoir hose connects the engine’s cooling system to the coolant reservoir tank. Its primary function is to transport excess coolant from the radiator to the reservoir when the engine heats up and coolant expands. When the engine cools down, the hose also allows coolant to flow back into the radiator from the reservoir, ensuring the engine maintains the proper coolant level. This helps prevent overheating and maintains optimal engine temperature.

• Leaks: A leak in the coolant reservoir or hose can cause the engine to overheat
• Overheating: A malfunctioning coolant hose or a leaking coolant reservoir can cause the engine to overheat
• Check engine light: A faulty coolant hose can cause the check engine light on the dashboard to illuminate due to a fault in coolant temperature and level measuring systems
