My Ride: 2005 330CI Vert ZHP
Hello, I have a 2005 330ci vert with automatic, today I tried to flush the coolant system but could only get out the coolant from the radiator and not the expansion tank. I do not have another drain plug besides the one under the expansion tank and I am confused on how to drain the expansion tank? If I could get some insight into how to drain the expansion tank that would be great.
