I have a 2009 Z4M 62k mls, the radiator coolant has never been changed, is it necessary to change/flush the system from time to time?
Thanks

I'd certainly recommend flushing/renewing every 50k, esp if you're not the 1st owner and don't know if it's been topped up a multitude of different coolants resulting in a sickly sweet and performance-compromised 'dirty sex on the beach with your engine' cocktail! :lol:

When I flushed the coolant in my 109k E85 it was a dirty brown nightmare fluid and stank like a mongrel thats been caught in a shower! Wish ida done it first thing after trying to solve cooling issues when i swapped in a new pump and stat but there you are :|
Flushed, replaced with Kroon SP11 and all good now. Can stand in traffic on a warm 30deg day and the needle stays in the vertical whereas it used to creep to the next quadrant :thumbsup:

Yes, can't do any harm changing it and be re assured, check the hose as well. D4dawg, like the wheels, tempted to buy a set.
