An expansion tank is where the coolant goes when it has nowhere else to go, but having a leak in this tank is almost like having no tank at all.You should replace a damaged expansion tank to be sure that your BMW 645Ci is not losing too much coolant.

this was my first time using your website and I initially was hesitant because the price was so much lower than the o.e.m one. not only did you send me a popular brand name product, it was a perfect fit. I am happy to say that because of it I am driving my BMW every day. its great to see in this day and age that there is a company that seems to be honest and care. thank you so very much.
