Hi there. Ive just had an expansion tank go on my 2005 E85 2.5 which I ordered genuine replacement with the thermostat for the auto box from BMW parts company in Germany. In the process of changing it I see that my radiator has seen better days. The bottom has a bulge in the core. Any one used after market rads and have an opinion on them. I can get a genuine one from the company mentioned for around 200 euro. Auto doc France ones start at 50 euro and up. Thanks in advance.
