The BMW 5 Series electronic water pump of Pacific Auto Network needs to be matched after replacement. With the engine cooled, open the lid of the water return kettle. Turn on the ignition switch, turn on the warm air mode of the air conditioner, adjust the temperature of the air conditioner to the highest and the wind speed to the minimum, press the accelerator pedal to the limit position for 1 seconds, and the engine will not start. The exhaust process has been started by pressing the accelerator pedal for about 12 minutes, then the liquid level in the coolant expansion tank is replenished to the maximum, and the kettle cover is closed, and the exhaust is completed.

If the air inside the electronic water pump cannot be removed correctly, it will easily lead to the phenomenon that the water temperature of the vehicle is too high. This is because there is too much air inside the cooling system, which makes the cooling liquid unable to circulate effectively, and the air expands when heated, resulting in too high pressure. At this time, if the pressure of the water tank cover cannot be released in time, the water pipe or even the water tank will easily burst, so it is very important to replace the antifreeze to exhaust the air.
in the process of exhaust, you need to rely on the battery. If the battery is nearing 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. It is forbidden to open the water tank cover or drain valve when the antifreeze temperature is very high to avoid scalding.
