The coolant temperature sensor is located on the passenger side radiator tank about 1/3 of the way down. It has a square back and faces toward the engine and is held in place by a spring clip. It has a two wire electrical connector and it is in direct contact with the radiator coolant via an o-ringed cylinder. You will loose coolant when changing it.
