Rad Size
Try a search on rads. There was a lot of talk about 2 years ago about what size you were supposed to recieve as opposed to what you got. Ford sent out checks to cover the cost of the upgrade. There were three sizes in 2001. One inch, one and a half inch and two inch. The two inch is just two one inch rads joined. Ford said the one inch is all you need. That is probably what you got. Most have not had a problem.
I think I was the one who started the RAD. issue.
