Product Description

Keep your BMW’s engine running at the correct temperature with this Cooltec water pump, designed for models equipped with M50, M52, M54, and S50/S52 engines. The water pump is a vital part of your vehicle's cooling system, circulating coolant through the engine and radiator to prevent overheating. This unit features a robust metal housing and a durable impeller, and comes complete with an O-ring gasket for proper sealing during installation.

This water pump is suitable for selected BMW models, including E34, E36, E38, and E39 series with the specified engines. To ensure compatibility, always check your vehicle’s model, year, engine size, and engine code before purchasing.

Common symptoms of a failing water pump include coolant leaks, overheating, noisy operation from the pump area, or visible coolant loss near the front of the engine. You may also notice steam from the engine bay or fluctuating temperature readings. Addressing these issues promptly helps avoid further engine damage.

When replacing the water pump, it is advisable to inspect the rest of the cooling system, including the thermostat and hoses, for wear or leaks. Proper installation with a new gasket is essential to ensure a reliable seal and efficient operation.
