The coolant temperature sensor (CTS) in Dodge vehicles with a 3.6L engine plays a crucial role in monitoring engine temperature and ensuring optimal performance. Locating this sensor can be essential for maintenance or replacement, especially if you're experiencing overheating issues or check engine lights.

Location of the Coolant Temperature Sensor

The coolant temperature sensor is typically found in the following locations depending on the specific model of the Dodge vehicle:

  • Dodge Charger (2015 and similar models): The sensor is located at the rear of the driver's side engine cylinder head. It is essential to ensure that the coolant level is below the sensor when replacing it to minimize leakage during removal.

  • Dodge Avenger (2012 and similar models): For this model, the sensor is positioned all the way to the right and slightly down on the head, facing forward towards you.

  • Dodge Journey (2011-2019): The sensor can be found in a similar location as in other models, typically on the left rear corner of the engine's left cylinder head.

Important Considerations

When working on or replacing the coolant temperature sensor, keep these important tips in mind:

  • Safety First: Always allow the engine to cool down before starting any work on the cooling system to avoid burns from hot coolant.

  • Coolant Drainage: Make sure to drain some coolant from the system before removing the sensor to prevent spillage. This can usually be done by opening a drain valve located at the bottom of the radiator.

  • Sensor Replacement: When replacing the sensor, ensure that you are using a compatible part to avoid further issues.
