How to Replace ECT Sensor on Dodge Stratus and Chrysler Sebring?

The Engine Coolant Temperature Sensor Replacing.
Please Note that this Procedure Covers all U.S. and Canadian models of the Chrysler/Dodge Avenger, Chrysler Sebring Coupe and Dodge Stratus/ Stratus Coupe models for Year 1999 to 2005.

The complete procedure to replace The Coolant sensor.
Working procedure of Coolant Sensor and Many more help details and Diagrams.

The procedure is as follows:----
Working of Coolant Temperature Sensor.
The Engine Coolant Temperature (ECT) sensor provides an input to the Powertrain Control Module (PCM). As the temperature increases, the resistance of the sensor decreases. As the coolant temperature varies, the ECT sensor resistance changes resulting in a different voltage value at the PCM ECT sensor signal circuit. The ECT sensor provides input for various PCM operations. The PCM uses the input to control air-fuel mixture, timing, and radiator fan on/off times.

NOW Refer the Removal & Installation Procedure.
The details covers Following Engine Models.

2.5L & 3.0L ENGINES

With the engine cold, partially drain the cooling system below the level of the Engine Coolant Temperature (ECT) sensor.
Disconnect the ECT sensor electrical connector.
Remove the ECT sensor.

To install:
Install the ECT sensor. Torque the sensor to 14 ft. lbs. (19 Nm).
Connect the ECT sensor electrical sensor.
Fill the cooling system to the proper level.

2.0L Engines
The engine coolant temperature sensor threads into the rear of the cylinder head.

2.4L Engine
The engine coolant temperature sensor threads into the front of the cylinder head.

2.5L & 3.0L Engines
The engine coolant temperature sensor is located next to the fill neck.

  1. Disconnect battery negative cable from remote negative terminal on shock tower and properly isolate to prevent accidental reconnection.
    Perform this operation only when the engine is cold.
  2. Drain coolant until level drops below sensor level.
  3. Coolant sensor electrical connector.
  4. Remove coolant sensor.

To install:
  1. Apply 3M® AAD part number 8731 or equivalent conductive sealant to threaded portion.
    It is imperative to use a conductive sealant.
  2. Install coolant sensor and torque to 60 inch lbs. (7Nm)
  3. Attach electrical connector to sensor.
  4. Fill cooling system.


These details will help.
