Sensor help needed
 

Does anyone know for sure what type of sensor is threded into the driver side head right behind cylinder #1? I broke it in half and need to know what it is to replace it.

its the coolant temperature sensor.its for the temp gauge in the dash
the other cts is located in ur water pump and that one monitors the temp and sends the info to the computer...

Thanks...that is why I was confused because I knew that the coolant temp sensor was in the waterpump. Little did I know there are two of the same sensors.
