The engine oil cooler is another “saved” item in this restoration. The factory drip marks on the side of the cooler would be extremely difficult to save if a restorer had to bead-blast this part. A detail restorers almost always miss is restoring the cooler with bare metal on the threaded inlet at the top, just to the left of the nut. The factory submerged the oil cooler in a vat of special thin paint. To prevent paint from entering the cooler, they inserted a cap over the inlet and outlet. The cap also protected the threads from paint, thus the bare metal.
