Coolant Loss Due to Leak from Expansion Tank on BMW 325Ci

An engine coolant leak may develop from the expansion tank resulting in engine overheating. When a cooling system component fails the entire cooling system should be inspected. It is not uncommon to find additional component have failed or are leaking.

Overheating can cause severe engine damage. If the engine begins to overheat it is recommended to stop at the first available location and have your vehicle towed to a repair shop.

I havent fixed it yet or maybe I have not diagnosed it but all I know is that it is leaking from the bottom of my car from the expansion tank bottle at the bottom of the car it seems like their is a sensor down there because the leak is right below it. I am hoping it is just that and not the water pump but how will I know that its from the water pump. Please send me some information to my email at albertma69@yahoo.com
