Where is my coolant going?
325 06 71000miles.
I received a low coolant warning. It was low and I added 3.5 cups of 50/50 BMW/Distilled Water. 200 miles later, it showed just a little low. I added 1/3 cup to bring back up. All levels taken cold.
I see no leaks, no white smoke and the system is under pressure when I open the cap.
It was low one other time in 2007 and 13000 miles.
What do you guys think. Should I be concerned?
