Product Description

This Cooltec hose is designed to connect the water pump to the cylinder head in your BMW's cooling system. As a crucial component of the cooling radiator hose assembly, it helps maintain proper coolant flow and temperature regulation, preventing engine overheating. The hose features multiple bends and a secondary branch for precise routing in the engine bay, ensuring dependable coolant delivery even in tight spaces.

Compatibility is specific to select BMW models, including F20, F21, F22, F23, F30, F31 through F36, and X1 to X5 models fitted with the N20 engine. Always check your BMW's model, year, engine size, and engine code before ordering to ensure correct fitment.

Common symptoms of a failing hose between the water pump and head include coolant leaks, visible cracks or bulges in the hose, engine overheating, low coolant levels, and a sweet smell from the engine bay. You may also notice steam from under the bonnet, erratic temperature gauge readings, or poor cabin heater performance.

Replace this hose if you observe signs of wear, leaks, or if your vehicle has experienced overheating. Hoses naturally degrade over time due to heat, pressure, and exposure to coolant, so proactive replacement can prevent costly engine damage.
