Recently reaplced the main radiator. Now the 7 has a leak from a radiator that is located towards the bottom between the oil cooler and main radiator. Does anyone know what this part is called? Please let me know. Thanks.

 

radiator between the "main" radiator and oil cooler .... post a picture

 

all i can think of is the AC cooler.

 

check the hoses and their connections, maybe you just didn't clamp one down right and coolant is dripping down the line, appearing to come from this mysterious second radiator.
