Despite its name, the water pump moves coolant around your engine. A failed water pump can have a devastating effect on your engine through overheating. You should be able to identify the signs of an E38 water pump failure to ensure that you replace the correct part before your engine is severely damaged.

What is the Water Pump in a Car?

The water pump is made to move water from the reservoir to the engine when a certain temperature is reached. The thermostat keeps tabs on the temperature, and when it reaches high enough, the water pump is activated to circulate coolant to the engine, where it absorbs heat, and to the radiator, where it releases that heat. If the water pump fails your engine will not be able to cool itself, resulting in overheating damage.

How Does a Water Pump Work?

The water pump is connected to the timing belt, which needs to be removed for access to the water pump. Check out the condition on the timing belt while working on a water pump, to save time on a future timing belt replacement. The water pump is driven by a pulley system that contains a drive belt that moves the internal propeller. This propeller is like a water wheel that pushes coolant up and out of the pump through the system. Wear and strain can cause damage to a water pump. Knowing when it starts to fail is ideal because you can replace the pump before your engine is harmed.

If the heater fails to blow warm air even after the engine has been running for several minutes, you may have a water pump problem because the coolant picks up heat from the engine to warm the cabin through the heating system, but if the water pump is not working, your interior may remain cold. There are many belts on your BMW 740iL, so this may not necessarily be an issue with the water pump, but it is something to look into.
