Okay, who tested the Relay? In my experience with that relay I have not been able to accurately test it and have replace to find that it was bad. And I take it the relay tested was located at the front frame rail on driver side.
Now with the fuse, was it tested with a meter or just looked at? I have found with just looking at them it is hard to tell if it is blown or not.
Also, is or was your engine light on? If it is now or was on and still is would have codes pulled. Could be that the coolant sensor that was replaced is defective, does not happen often but it does happen.
Note : A bad sensor will turn engine light on. A bad relay in most cases will not.
I have attached diagrams.
Fuse #27 is the 40 amp radiator fan.
