Well after I drained the coolant and bleed I have been driving around for 3 days. The temp has never shown more than 95 degrees usually 94 and zero coolant has dissappered from the expansion tank. Seeing as how the thermostat and pump were changed 11k miles ago, I am going to change out the rad expansion tank and fan clutch. Then call it a day. I have no proof those have been changed
I did notice when I drained out all the coolant it was Prestone Green. Not BMW blue. Previous owner had the t stat and water pump changed at a BMW dealership and they put in Prestone???? Scam artists!
