Where is the BMW 5 Series electronic water pump?

Pacific Auto Network's BMW 5 Series electronic water pump is in the engine compartment. After the engine is cooled, the lid of the return kettle is opened. Turn on the ignition switch, turn on the air conditioning warm air mode, adjust the air conditioning temperature to the highest and the wind speed to the lowest, and press the accelerator pedal to the bottom position 10 second, and the engine will not start. The exhaust process started by pressing the accelerator pedal and lasted about 12 minutes. Then the liquid level in the coolant expansion tank is replenished to the maximum, and the lid of the kettle is closed to complete the exhaust.

If the air inside the electronic water pump can't be removed correctly, it will easily lead to the phenomenon that the water temperature of the vehicle is too high, because there is too much air inside the cooling system, which makes the coolant unable to circulate effectively.

In addition, the air is heated and expanded, generating excessive pressure. At this time, if the water tank cover can't release the pressure in time, it is easy to cause serious faults such as water pipes and even water tanks bursting. Therefore, it is very important to replace antifreeze to exhaust air.

In the process of exhaust, you need to rely on batteries. If the battery is close to its service life, it is best to connect the battery with an external charger at the beginning. Exhaust must be carried out when the engine is cold. When the antifreeze temperature is high, it is forbidden to open the water tank cover or drain valve to avoid scalding.

The exhaust mode of BMW 5 Series electronic water pump has the following two points:

1, turn the ignition switch to the second gear, turn the air conditioning fan to the lowest, and then turn the temperature to the maximum;

2. Turn on the low beam, press the accelerator pedal for ten seconds, and then hear the sound of the auxiliary kettle discharging water.
