Product Description

Ensure your BMW’s engine stays at the correct operating temperature with the Cooltec HOSE RADIATOR UPPER, designed for the cooling system. This upper radiator hose channels coolant from the engine to the radiator, playing a vital role in heat dissipation and overall engine health. Featuring flexible construction, protective mesh sleeves, and secure plastic quick-connect ends, this hose is built to match the specific routing and requirements of BMW 1, 2, 3, and 4 Series F20-F36 models with the B38 engine from 2014 onwards.

This part is compatible with selected BMW 1 Series, 2 Series, 3 Series, and 4 Series models (F20, F21, F22, F23, F30, F31, F32, F33, F34, F35, F36) fitted with the B38 engine from 2014 onwards. Always confirm your vehicle’s model, year, engine size, and engine code before ordering to ensure correct fitment.

Common symptoms of a failing upper radiator hose include coolant leaks, visible cracks or swelling on the hose, overheating engine, low coolant levels, steam from the engine bay, and a soft or spongy hose feel. If you notice any of these issues, the upper radiator hose may need attention.

Replacing a worn or damaged radiator hose is essential to prevent coolant loss and overheating, which can cause severe engine damage. It is recommended to inspect hoses during regular maintenance and replace them at the first sign of wear, leaks, or age-related deterioration.
