Engine Coolant Temperature (ECT) Sensor Chevrolet Impala 2.5L 2014-2020 Location and Replacement

In this video, I show you only the exact location of the Engine Coolant Temperature (ECT) Sensor on a 2014-2020 Chevrolet Impala 2.5L.

Finding the precise spot where this sensor is installed will save you time and eliminate the guesswork during your DIY repair.

Common Symptoms of a Bad Coolant Temperature Sensor:

• The check engine light comes on (frequently with codes like P0117, P0118, or cooling system performance codes)
• The temperature gauge on the dashboard drops to zero, moves erratically, or spikes into the red zone
• The radiator cooling fans run continuously at high speed or fail to turn on at all
• A noticeable drop in fuel economy and poor engine performance
• Hard starting or rough idling when the engine is cold

Safety First

Always prioritize safety when working on the cooling system. You must ensure the engine is completely turned off and cool to the touch before getting started; opening or working near a hot system can release pressurized boiling fluid and cause severe burns. Protect your eyes and skin by wearing safety glasses and fluid-resistant work gloves, and always keep your full focus on the job.
