Hello, I am trying to replace my radiator on Bmw z4 2007 3.0 I with the n52 engine and automatict transmission. I orders a nissens radiator. While replacing the radiator, I found out eh original oem one have an extra hose connector under the lower hose while the new nissens ones does not have one. I don't know what that hose connector is. I can't find any after market radiator with the similar type. May I know what it is and should I buy the OEM one or are there any after market supply for his car. I attached a picture of the OEM radiator. Thanks.
