In this video, I show you the exact location of the Engine Coolant Temperature (ECT) Sensor on a 2012-2016 Chevrolet Malibu 2.5L. Pinpointing exactly where this sensor is threaded into the cooling system housing is an essential first step for a smooth DIY vehicle repair, saving you time and preventing unnecessary searching under the hood.
Common symptoms of a faulty Engine Coolant Temperature (ECT) Sensor include:
- Your dashboard temperature gauge displays erratic readings, stays completely dropped at cold, or maxes out irregularly.
- An active Check Engine Light (CEL) on your dashboard, often accompanied by cooling system performance codes like P0117, P0118, or P0128.
- The radiator cooling fans running continuously at maximum speed, hard engine starting when cold, or a noticeable drop in fuel efficiency.
Safety First: The cooling system operates under high pressure and temperature. Always ensure the engine is completely cool before working near or removing the sensor, protect your hands and eyes by wearing durable gloves and safety glasses, and stay fully focused and attentive throughout the entire job.
