Default radiator install trouble...

ok, so i got the stock radiator out. on the water pump there is the two major inlets and then there is a small one coming off the bottom to the driver side...well a hose came off this and went to a small outlet at the bottom of the radiator(driver side). the new radiator(be cool-right part #) does not have a male fitting there like the old one...it has female threads. so how do i hook the hose up to that?am i missing something?or do i reroute that hose? please help guys,i cant proceed til i know something. also the car is an m6 just so you know.

I put a NPT plug in the radiator and sealed up the hose right at the pump. This is the loop line for the factory oil "cooler"

I've had this line plugged for a while with no issues. There are aluminum NPT plugs available and would probably be the best thing to twist into the aluminum radiator. Of course, when I installed my Be Cool, I could only dig up some steel plugs. Next time I drain the rad, I'll put some Earls plugs in.
