  1. E85 / E86 Z4 (2003-2008)
    2005 Z4 2.5. 70K miles. Winter car in Florida. Last spring I was was told by an indy that my coolant expansion tank was leaking. I went back to Maine and garaged the car. After I got back to Florida I checked the coolant regularly and did not see it going down. A few days ago there was a lot...
