Product Description

Ensure your BMW's cooling system operates efficiently with the Cooltec HOSE RADIATOR UPPER, designed specifically for the upper radiator connection in your vehicle. This hose is responsible for carrying coolant from the engine to the radiator, helping to regulate engine temperature and prevent overheating. It features pre-formed bends, protective sleeves, and durable quick-connect fittings for a secure and leak-resistant installation.

This radiator hose is compatible with a range of BMW models, including the 1, 2, 3, and 4 Series F20-F36, specifically for 120i to 430iX models equipped with the B48 engine from 2011 onwards. Always confirm your BMW's model, year, engine size, and engine code before ordering to ensure the correct fitment.

Common symptoms of a failing upper radiator hose include visible coolant leaks, low coolant levels, overheating, soft or swollen hose sections, cracks or splits, and poor coolant circulation. You may also notice the engine temperature gauge rising more quickly than usual or steam coming from under the bonnet.

It is recommended to replace the upper radiator hose at the first signs of wear, such as bulging, cracking, or leaking, or as part of regular cooling system maintenance. Timely replacement helps prevent sudden breakdowns and protects the engine from costly overheating damage.
