After reading most of the previous post on this topic (can't complain that I Haven't tried the search first wink ) it seems that there was never a clear cut as to new antifreeze/coolant can be added to the existing one.
Mine is below min. and it is winter time... I guess I can anticipate problem when the hotter will arrive.
Bottom line, I called my dealer to ask what coolant/antifreeze they would recommend and their answer was any ..... !!!
So now I am totally confused ! Should I drain the existing one before topping up ? I also heard that this coolant need to be replaced every 2 or years depending og the type !
Any having any experience of this ????
