I have the same problem on a 2007 Duratec +4, has an Alloy rad etc but the fan doesn’t seem to kick in at all.
Could it be a relay or is it more likely a connection issue?
Can anyone advise what temp the fan should come on at for both high and low speed options.
Many thanks
Will
One thing to check... On the 2007 Duratec you will most probably have the 20p nylon fan connector which is dreadfully unreliable in this application. Mine failed stopping the fan from working so replaced with a ceramic connector block.

The low-speed fan kicks in around 100C and the high-speed around 105C. For what it’s worth, one of the many tricks of the Ford dealer’s OBD diagnostic software (IDS), is that it is able to run a fan test which is quite useful and reassuring.
