This is not possible on a modern vehicle like the Villager.
my 1997 mercury tracer ran hot and now will not start what could be the problem?
Hi, The answer I hhave in my '97 service book is the with wire is the hot all the time. Steve H.
Well, assuming your fan is operating normally, it's possible your radiator is plugged up, either internally with gunk, or externally with dirt, bugs, and fluff.
if the top hose is hot then the thermostat is opening
Run a fused/switched wire from ignition sensitve circuit in fuse block or dash directly to motor harness
The engines thermostat is probably stuck open or has been removed, so change the thermostat and this should fix your problem.

is the orange wire always hot
Low coolant? Bad thermostat? Heater core plugged or airbound? Heat control cable not working?
It should be light green with a yellow stripe, it is hot for the memory. The yellow with black stripe is for ignition.
If it is an after market stereo, sound as if someone spliced the stereo power source wire (Hot Wire) into the wire going to the headlight switch.
There has been some talk that the Mercury Villager doesnt have a great cooling system, sometimes a bigger radiator replacement might help.. but either way you have to keep the coolant, timming, etc in perfect state. The reason why it goes from normal to hot then back to normal is because that is usually when the temperature rises hi enouth for the thermostat to open up and lets the cooling back in circulation thru the whole system...
