Where is the coolant temperature sensor located on the new Jetta?

[StJoshua]

The coolant temperature sensor on the new Jetta is located on the water jacket of the engine block or cylinder head. Below is relevant information about the coolant temperature sensor: 1. Coolant temperature sensors are divided into two main types. Regardless of the type, their internal structure consists of a thermistor. 2. Its resistance ranges between 275 ohms and 6500 ohms. Moreover, the lower the temperature, the higher the resistance, and the higher the temperature, the lower the resistance. 3. The function of the first type of coolant temperature sensor is relatively simple: it uses the change in its internal resistance to alter the current passing through the sensor, thereby driving the change in the temperature gauge and indirectly indicating the engine's operating temperature. 4. The second type of coolant temperature sensor has no structural differences, but its function is to provide the engine control unit with an analog signal of temperature changes.
