Problem Description and Possible Solution
A coolant leak may develop from the radiator. Ford has released and updated radiator and powertrain control module (PCM) software update to address this issue. The software update includes revised cooling fan operating parameters. Failure to complete both service procedures may result in repeated radiator failures.
Average mileage: 127,119 (65,000–220,000)

My radiator is leaking from the seam too so I have been investigating this problem to some level of detail.
Firestone checked the problem (for a fee) and was told by the OEM provider of the new radiator about a Service Bulletin on the problem. The service bulletin ONLY lists the 4.0L engine but the OEM insisted that it applies to the 4.6L too. Paid money (again!) to my local Ford dealer who I thought would find the problem and the bulletin and hopefully repair it under warranty or some other provision. Bottom line ... the Ford dealer shows no record of the 4.6L having this problem and is confused by what the OEM is saying. Firestone trusts this OEM who insists that the problem is well known and reprogramming is required. Too bad ... who to believe?
I just paid Firestone to do the repairs ... need my car. Told Firestone to flash the computer with the upgrade if it showed necessary. Why take the risk?
But very disappointed in Ford to be honest. This appears to be a well-known problem (OEM said it popped right up on his computer when the part number was entered) that is fixed by a software upgrade to what sounds like an initial design flaw. But Ford disavows any knowledge of the problem for the 4.6L. Ogden Lincoln Mercury in Westmont, IL is the dealer by the way.
had a continual problem with leaking fluids never was really fixed I finally added stop leak which I had to do many times finally it blew my head gasket had to pay over $1600 to get engine repair & bought a new radiator nothing but continuos problems since I bought it in 2010 leaking etc even after that the hoses went TWICE to the radiator bad workmanship on this vechicle
After replacing the radiator at a dealership, and putting on new hoses, the car still is overheating. I've been back to the dealership 4 separate times....they seen confused about what's causing the problem.
What should I ask them to try....reprogramnming the PCM ?
Appreciate any insight you could give me.
