Motorcraft Coolant Temp Sensor 94-97 7.3L Powerstroke

Ford used 2 different styles of temperature sensors on the 7.3L engines that look the same but function differently. If you touch your sensor wire to the chassis and your temp gauge reads full scale, you will need the F1SZ10884A sensor. If it does nothing, you will probably need the DOZZ10884A sensor.

There is also one difference in appearance that may be hard to distinguish on the sensor once is has been installed on the engine for years. There is a colored ring in the sensor around the single electrical pin. One is red and the other sensor is green. If you have a green colored ring, you need the F1SZ10884A, red is the DOZZ10884A sensor.
