Radiator Flush Solution
Is there a recommended "Radiator Flush Solution" to use with our precious BWW's? Or will running the car with distilled water for a while dissolve any of the mineral build up in the cooling system, before refilling it with my 50/50 coolant mixture?

How did you drain the fluid? I saw in the bentley manual you need to drop the intercooler to get to the radiator drain?

Haven't done a flush since the 90's. With back to back leasing and many life changes, haven't owned a car long enough to warrant a flush. With the BMW coolant and distilled water, you're saying no flush solution is required?

If that lifetime words you are refering to from the stealership then its not a lifetime. BMW use the word life time as meant to only up to 100k.

being that everything in your engine is either aluminum or plastic except for the 335 in which your center section of your turbo is steel..you really SHOULDNT have a buildup issue...that being said a simple drain and refill will be all you need to do a coolant "flush"

+1 also you would need to flush if you used tap water and there was a build-up of mineral deposits.
