The coolant temperature sensor on a 2000 Dodge Neon is located on the thermostat housing. The thermostat housing is located on the front of the engine, just below the upper radiator hose. The coolant temperature sensor is a small, cylindrical sensor with a single wire connector.
To remove the coolant temperature sensor, follow these steps:
1. Disconnect the negative battery terminal.
2. Drain the coolant from the radiator.
3. Remove the upper radiator hose.
4. Remove the two bolts that hold the thermostat housing in place.
5. Lift the thermostat housing off of the engine, being careful not to spill any coolant.
6. The coolant temperature sensor will be located on the bottom of the thermostat housing.
7. Disconnect the wire connector from the coolant temperature sensor.
8. Remove the coolant temperature sensor from the thermostat housing.
9. Install the new coolant temperature sensor in reverse order of removal.
Note: It is important to use a new gasket when installing the thermostat housing. The old gasket may be damaged and could cause a leak.
