The coolant tempature sensor on the 2.3L is located in the water Outlet pipe at the front of the engine.Check the resistance value of the sensor when its completly cold (50-65 degrees).it should be about 40,000 ohms.Start the engine and bring it up to operating temp (180-220 degrees f )the resistance should be lower, approx. 3,000 ohms.if the values are correct check the wire that connects to it. It sholud be approx. 5.0 volts dc.

The gauges on most Rangers show "nothin" even when they do work right.
1. Ford gauges aren't models for accuracy.
2. While you want an engine to run warm...you don't want it running soooo hot that all the hoses and wiring go crispy sooner than later.

Like I said I'm not familar with the 2.3, take it out and see what fluid comes out, can't really hurt anything.

resistance should be about 100 ohms at normal operating temp
(195 degrees).

You mean theres not a sending unit on the thermostat housing/outlet? I guess I should have asked what year is your truck? I got the location and resistance values from HAYNES manual 36071, 93 thru 2000.
