BMW 740iL Water Pump Pulley Replacement at your home or office.

What is the Water Pump Pulley all about?

Your car’s engine produces a great deal of heat, which can easily damage internal components. To ensure that your engine runs properly and doesn’t lock up, it needs to maintain the right temperature (called the operating temperature). This is done in large part with engine coolant. Coolant circulates through the engine, absorbing heat and then transporting it to the radiator, where the fluid is cooled by air, before once more beginning the journey through the engine. The water pump is responsible for pushing coolant through your engine using impellers inside the engine. The pump is turned by a pulley, which is in turn moved by your engine drive belt. If the pulley is damaged, bent, or seized, the drive belt can come off the pulley and the water pump will cease to turn. If that happens, the engine will overheat.
