I was looking at one of the Ford websites and it shows :
For a 1988 Lincoln Town Car , 5.0 liter / 302 cubic inch V8 engine :
( Motorcraft RT-1139 engine cooling thermostat , 190 * Fahrenheit )
You might need a new thermostat or heater core.
More then likely you need to replace the Thermostat.
And what about it do you need one ? selling one ? Fixing one?

If there is no cooling system, the engin will overheat.
So that there's a power source to propel the vehicle.
You can locate the thermostat on the front of the engine follow the upper radiator hose back to the engine - the thermostat is located in the engine housing that the hose connects to, there are usually 2 bolts that you need to remove, take of the housing that holds it in place, remove the gasket and clean, test the thermostat or put in a new one - to test the thermostat hold it over a boiling pot of water with tongs if the thermostat opens this is not your problem if it does not open then your thermostat is faulty. Replace and reseat thermostat, replace the gasket, replace the bolts and radiator hose.
You should check the thermostat to see if it is operating corectly, or your system may need to be perged.
It does not have a thermostat sensor. There is no need for one....
Vehicle will run without a thermostat - however will not run as efficiently and will have not heat
All cars need a thermostat for proper operation and longevity.
Yes you definitely need a thermostat to keep engine from overheating + or overcool,g especially in cold weather.
