Product Description

Ensure your BMW's cooling system operates efficiently with the Cooltec Hose Water Pump to Head Reinforced, designed for robust coolant transfer between the water pump and cylinder head. This reinforced hose is built to withstand the pressures and temperatures found in modern BMW engines, helping to prevent leaks and maintain optimal engine cooling.

This hose is compatible with selected BMW models, including E81, E87, E90, E60, E84, and E85 fitted with N46 or N46N engines. It is important to check your vehicle's model, year, engine size, and engine code to confirm compatibility before ordering.

Common symptoms of a failing water pump to head hose include coolant leaks, visible cracks or bulges in the hose, engine overheating, low coolant warning lights, steam from the engine bay, and unusual coolant odours. You may also notice decreased heater performance or fluctuating temperature gauge readings.

Replace this hose if you observe any signs of wear, damage, or leaks, especially if your BMW has high mileage or has experienced overheating issues. Timely replacement helps avoid costly engine damage and ensures reliable cooling system performance.
