I had the cd4e in my 02 Cougar rebuilt last week. Picked the car up today. The shop tells me that the radiator is leaking. It looks to be along the seam by the cooler lines. I'm wondering now if they caused it, maybe from prying on the lines, as they had to be disconnected for the job. It's an original radiator, so it's quite possible that it was on the way out. I just don't know.
