Engine Coolant Temp Sensor
 

Does anyone know where to get an engine coolant temp sensor for a 2000 Jeep Cherokee Sport with the 4.0L engine? See attached photo. This is not to be confused with the temperature sending unit that sends the signal to the temperature gauge.

Your 2000 only has the one sensor, and it's on the front of the engine at the thermostat housing. I bought a replacement at Advance Auto for $18.

What is that picture of?

That is not a temperature sensor or sender.
