For a Ford LTD Crown Victoria 1984 5.0 engine, how do you adjust the thermostat?

The carburetor is Central Fuel Injection. (It's an electronic ignition.)

Added (1). The thermostat is on the automatic choke control.

I will appreciate greatly your technical support.

Added (2). Throtle body carburetor with throttle position sensor.

Added (3). And the thermostat is electric.

I think the only adjustment is to bend the connecting rod a bit to make it turn OFF quicker or slower.

Hmm, trying to remember what Motorcraft set-up is.Throttle-body injection, is there a circular black plastic housing on side of TBI retained by 3 small screws? If so, loosen screws and rotate housing clockwise to increase spring tension, making t-stat pull off @ higher temp, or other way to do opposite. Should Really buy repair manual for your car, you get a lot of wild-*** guesses here!

I'm sure that someone will correct me if I'm wrong, but I'm pretty sure thermostats are non-adjustable. From my understanding, you change the thermostat for summer and winter i.e. Run a 160 in summer and a 180 in winter or something like that.
