Product Description

The Cooltec HOSE RADIATOR UPPER is designed for the cooling system of select BMW models. This upper radiator hose plays a crucial role in directing coolant from the engine to the radiator, ensuring efficient heat dissipation and optimal engine operating temperature. Its construction features moulded curves and an integrated smaller hose for precise fitment within the engine bay.

This part is compatible with specific BMW models, particularly those with the M57N2 engine such as the E90 325d, 330d, and 335d. Always confirm your vehicle's model, year, engine size, and engine code before placing your order to ensure correct fitment.

Common symptoms of a failing upper radiator hose include coolant leaks, overheating, visible cracks or bulges in the hose, low coolant levels, steam from the engine bay, and a soft or spongy hose texture. If you notice any of these warning signs, it is important to inspect your hose for wear and damage.

Replacement of the upper radiator hose is advised when there are signs of age, damage, or leaks. Swapping out a worn hose helps prevent coolant loss and potential engine overheating, protecting your BMW’s engine from costly damage.
