How to Bleed the Coolant in a BMW 320li?
2 Answers
For the BMW 320li, after adding coolant, open the coolant filler port and start the vehicle, maintaining this state for a few minutes to bleed the system. Below are detailed steps regarding bleeding the coolant in a BMW 320li: 1. Precautions: The coolant used in the vehicle requires regular inspection and periodic replacement. When replacing the coolant, ensure to use the same brand and model as the original coolant. 2. Vehicle Specifications: The BMW 320li is a mid-size sedan, also known as a B-segment car. It features a MacPherson strut front suspension and a multi-link independent rear suspension.
I have hands-on experience with this. The bleeding process after replacing the coolant on a BMW 320Li is quite particular, especially with that electric water pump. First, park the car on level ground and open the expansion tank cap when the engine is cool. Remember to turn the key to the ON position but don't start the engine - set the AC to maximum temperature and minimum fan speed, which is crucial as the electric water pump will activate automatically for bleeding. Wait until bubbles stop emerging from the radiator neck, then start the engine and let it idle for about ten minutes. Keep an eye on the temperature gauge - if it rises rapidly, shut off immediately as this indicates incomplete bleeding. Finally, top up the coolant to the middle level mark, drive about two kilometers, then recheck the level. The whole process takes about twenty minutes, and skipping any step could easily lead to abnormal coolant temperature.
