BMW X1 F48 2016 xDrive25i coolant flush

This video shows how I drained the water from my xDrive25i and filled it with coolant and bleed (vented) the system.
I did try the various methods shown in other videos and forums but I couldn't hear any electric pump activity, so I used the old school method that never fails.

Thank you 😊

Hi, how did you remove the tube to drain the coolant? I’m trying to remove it right now with my hands and it’s so hard it doesn’t budge.

[@kenkanfix]

hi, you need to pull the clip first before you can pull the hose out

[@ippytuklulu]

@@kenkanfix do you know why the coolant isn't draining entirely? There is still some left over and only 2 liters or so drained out.

[@kenkanfix]

@ippytuklulu there's some around the cylinders since the thermostat would be closed. If you want to get all old coolant out you would have to do multiple drain/fill.

@@kenkanfixok thank you. Do you have any suggestions on the most efficient way of doing the fill/drain in my situation? I have premixed coolant and I have already flushed the system with distilled water. How do I calculate how much premixed coolant to add? Wouldn’t I need to get some concentrate since I’ll never reach 50/50?

@@kenkanfixI just learned the cap needs to be on for the overfill reservoir to drain. I thought it wasn’t draining because I still do liquid there
