NTK EF0178 coolant temperature sensor for the 2018-2021 Jeep Wrangler 4-cylinder 2.0L and other vehicles determines the coolant temperature and sends an analog signal to the ECM. The ECM uses that signal to set the air/fuel ratio and to run the cooling fan or fans and the temperature gauge.
- Mounting clip or clips included where applicable
- Thermal conductive grease inside the brass housing increases sensor response time
- Thread sealant or O-ring installed where applicable
- Thermal conductive grease provides accurate temperature transfer to the thermistor
Quick facts
- Part: NTK EF0178 coolant temperature sensor
- Also called: engine coolant temperature sensor
- Fits: 2018-2021 Jeep Wrangler 4-cylinder 2.0L and other vehicles
- Material: Brass housing
- Condition: New
Also called an engine coolant temperature sensor, it may sit on the cylinder head, engine block, thermostat housing or intake manifold. A check engine light, an erratic or dead temperature gauge, or erratic or no cooling fan operation can mean the sensor is worn. A cooling fan relay or a wiring connector can produce similar symptoms, so track down the cause before you replace anything.
Fits
This coolant temperature sensor is a direct-fit replacement for the 2007-2016 Jeep Compass 4-cylinder 2.0L or 2.4L and the 2019-2021 Jeep Cherokee 4-cylinder 2.0L, along with further Chrysler, Dodge and Jeep models. Open the "Vehicles it fits" section and enter your exact model and engine to see whether yours is covered. An engine takes one sensor, and this listing is one sensor.
