There are 2 item located in the same area one is a little below the is on the housing of the one you replaced, the top one is a low coolant sensor and the one on the bottom is the temp sensor.

    the one you replaced is not a temp sensor it is a low coolant/fan switch. the actual temperature switch is located on the thermostat housing on the underside, not really in a easy spot to see, these are the only 2 sensors for the purpose if you are still over heating you may have a relay or fan problem.

2002 dodge diesel Temperature gauge not working,have changed Coolant temperature sensor, still not working

possibly change the wrong unit
gauges work from a sender unit not a sensor
it is located next to the thermostat housing normally and has only 1 wire connection
they work by having power through the gauge to the sender through variable resistance that is affected by heat to ground
test disconnect the wire from the sender
turn on the ignition key , ground out the wire and the gauge should go straight to full hot
sensors on the other hand have more wires and relay the coolant temp to the ECM so that air/fuel ratios can be adjusted , and fans switched on as required

How to install a coolant temp sensor in a 1995 ford escort

The coolant temperature switch and fan control switch are located sie by side, mounted in the steel portion of the heater hose that runs from the thermostat housing to the firewall, it is underneath the air intake tube and the ignition coil pack, mounted to the back of the cylinder head. Either drain out some coolant or be very quick, and you can unplug and unscrew each switch from the hose and replace it with a new one. Make sure the engine is cold. After replacing make sure to check the coolant level add as neccessary. The single wire connector switch is for the guage, and the other is for fan control. Hope this helps, let me know.

follow the upper hose to the housing it goes to and if you see bolts there the thermostat should be under it. make sure to have coolant on hand as you will loose some.
