I have a 2009 BMW 328. BMW claims it's "lifetime fluid". There's no such thing as "lifetime fluid". The last time the coolant was flushed was in July of 2018 at 64k miles(by the PO). I am at 72k miles right now. I plan on doing a coolant flush later in the spring or summer. I'll probably stick with flushing it every 3 years (Since I hardly drive the car).
I watched a video on youtube where the guy drained the coolant from the drain plug and then ran the water pump while the coolant was still draining. Isn't the water pump running dry?? From what I am reading, a lot of folks drain it from the drain plug and then drain it from the water pump/thermostat hose.
Here's the video:
