Bleeding the coolant

ok here’s a video on how to bleed the cooling system,,,remember you must have the door latch lock and do not grab the door handle and unlock it,,,once the door latch open up the water pump will stop bleeding,,,because the door is then open.image Reminder the water pump will cycle,,,it will pump water and the stop and then start-up again,,,,that is all normal,,,the water pump will cycle a lot,,,,if it doesn’t bleed,,,remember try the bleeding again with the a/c button on,,,,after it bleeds for a while,,,,top off the coolant and go for 2 mile test drive,,,,after test drive check water level,,,,you might have to add water that is normal,,,,don’t worry sometime it takes a couple of times.

    Hi Andreas, i have made the experience on my F13 (N63) that only a refilling of coolant under vaccum removed the water noises in the heating.

    On the E92 N51 motors, how would you drain all the coolant out? I know how to drain from the radiator, does it also have a drain on the block? My goal is to drain as much as possible because someone put the wrong kind of coolant in. Also anything else I have to do to bleed besides cycling the pump? Thanks so much!

    Hello BMWTechnician, I just changed my coolant. The coolant that came out surprised me, it was a brown orange color. I bougot the car used. It is a 2011 328i. The coolant in the reservoir was green and looked fresh, but this is what came out of the radiator. http://i67.tinypic.com/10cpxcw.jpg
