Product Description

Ensure your BMW's cooling system operates efficiently with the Cooltec Hose Radiator Lower, designed specifically for the lower section of your vehicle's radiator. This hose plays a critical role in directing coolant from the radiator back to the engine, helping to maintain optimal engine temperature during operation. Featuring moulded curved shapes and integrated plastic quick-connect fittings, this part is engineered for a secure and leak-resistant connection within the cooling system. The additional outlet branch on one hose supports precise coolant routing, as required for your specific BMW model.

This lower radiator hose is compatible with selected BMW models, including those equipped with the N46 and N46N engines, such as the E81, E82, and E87 118i and 120i. Always confirm your vehicle's model, year, engine size, and engine code before ordering to ensure proper fitment.

Common symptoms of a failing lower radiator hose include coolant leaks, visible cracks or bulges in the hose, overheating, low coolant levels, or a soft and spongy hose texture. You may also notice poor heater performance or the appearance of coolant puddles under your vehicle.

If you experience any of these symptoms, it is important to inspect and replace the lower radiator hose promptly. Over time, hoses can degrade due to heat, pressure, and exposure to engine fluids, leading to possible failure and engine damage.
