The fan is held on by two nuts at the top and tabs at the bottom. It will lift out, but it is a tight fit. There are a couple wiring harnesses clipped to it as well, you will need to reach down inside with a plier and pinch the clips shut to allow them to pop off.
The Villager has an electric fan and does not use a "fan belt".
I would guess somewhere around 210-230 degrees. This may/may not be right, but if the fan isn't kicking on then there may be another issue present. i.e. Radiator Fan control relay switch. Usually mounted on the body down by the bottom of the radiator.
There are several things that can cause your 1998 Mercury Villager rear fan to stop working. The most common cause is a disconnected or corroded ground wire.
Under the dash.
Simply drain the system, disconnect the hoses and lines, unbolt the fan (2 screws), remove the retainers at the top, and it should come right out.

Is it the fan behind the radiator, or the fan that blows air into the cabin?
The radiator fluid is low or you parked the car at am angle.
Right inside the roof housing where the air comes out.

Good luck with that fan motor. The blade is fused to the motor shaft an will most likely break when you try to separate them thus, the new motor they sell you will be useless.
In the relay box in the engine compartment with the other relays.
