If your car has an automatic transmission, it might be the heat exchanger for the transmission oil (Radiator replacement). How's the transmission oil look?

Whatever you find, and repair, you want to get the oil out of the cooling system PDQ. It raises h*ll with all the rubber bits: hoses, valves, seals....

Good Luck, MBL
