Engine Coolant Temperature (ECT) Sensor Chevrolet Equinox 2.4L 2010-2017 Location and Replacement

In this video, I show you only the exact location of the Engine Coolant Temperature (ECT) Sensor on a 2010-2017 Chevrolet Equinox 2.4L.

Pinpointing the precise spot where this sensor is threaded into the thermostat housing side of the engine block will save you time and eliminate the guesswork when planning your DIY replacement.

Common Symptoms of a Bad Engine Coolant Temperature Sensor:

• The dashboard temperature gauge reads completely cold, behaves erratically, or spikes straight to hot
• The engine cooling fans run constantly at maximum speed as a fail-safe measure
• The check engine light comes on (frequently with diagnostic trouble codes like P0117, P0118, or P0128)
• Hard starting issues, especially when the engine is cold, or a noticeably rough idle
• Poor fuel economy and black smoke from the tailpipe due to the engine computer running too rich

Safety First

Always prioritize safety when opening or working near any part of the engine cooling system. Never attempt to remove the sensor or open the coolant recovery tank while the engine is hot. The cooling system is under high pressure, and escaping boiling fluid or steam can cause severe burns. Ensure the vehicle is parked on a flat surface, the engine is completely cold, and the cooling system pressure has been safely relieved. Protect your eyes and skin by wearing safety glasses and fluid-resistant work gloves, use a clean drain pan to catch escaping antifreeze, and keep your full focus on the task.
