Product Description

The Cooltec HOSE RADIATOR UPPER is a crucial component in your BMW's cooling system, responsible for carrying coolant from the engine to the radiator. This hose assembly features robust rubber construction with multiple bends and integrated quick-connect couplers for a secure and leak-resistant fit. It also includes an auxiliary hose and dedicated ports for sensors or connectors, ensuring compatibility with models equipped with advanced cooling monitoring.

This radiator hose is specifically designed to fit selected BMW vehicles, particularly models such as the BMW E46 318i with the N42 engine. Always confirm your vehicle's model, year, engine size, and engine code before placing your order to ensure correct fitment.

Typical symptoms of a failing upper radiator hose include visible coolant leaks, bulging or soft spots on the hose, engine overheating, low coolant warning lights, and the presence of cracks or splits along the hose. You may also notice steam from under the bonnet, or a sudden drop in coolant level without visible leaks elsewhere.

Replacing the upper radiator hose is advised if you observe any signs of wear, leaks, or if the hose feels excessively soft or brittle. It is also recommended to replace the hose during major cooling system maintenance or after a significant overheating event to prevent future issues.
