Look at something very similar, in my Mustang 2001, 8 cyl, and the piece was the oil cooler, this piece is located below the oil filter, inside the piece I suffered correctness and the oil passed to the cooling system (radiator) changes the piece and ready, the car is 100. You will have to purge your radiator several times, to eliminate the oil residue that remains in the radiator. The piece is simple to remove you will have to tell your mechanic to check it, normally everyone is inclined to the heads of the heads and head rectification, there is no need. I hope it serves you, greetings.
