Product Description

This Cooltec hose is designed to connect the expansion tank to the radiator in select BMW models, playing a vital role in your vehicle's cooling system. It ensures the proper flow of coolant between the expansion tank and radiator, helping to regulate engine temperature and prevent overheating. The hose features a contoured design with secure connection points, including a quick-connect fitting for easy installation and a plain hose end for a tight seal.

This part is specifically compatible with BMW models, including certain E60, E61, E63, and E64 series vehicles. Always confirm your BMW’s model, year, engine size, and engine code before ordering to ensure the correct fitment for your car.

Common symptoms of a failing expansion tank to radiator hose include coolant leaks, visible cracks or swelling in the hose, engine overheating, low coolant warnings, and a drop in coolant levels. You might also notice steam from the engine bay or a sweet smell from leaking coolant.

Replacement is recommended if you observe any signs of wear, damage, or leakage, or as part of routine cooling system maintenance. Regular inspection and timely replacement help avoid costly engine repairs due to overheating or coolant loss.
