Thermostat Chevrolet Impala 2.5 2014-2020 Location and Replacement

In this video, I show you only the exact location of the thermostat housing assembly on a 2014-2020 Chevrolet Impala 2.5L.

Seeing the precise spot where the thermostat is bolted to the engine will save you time and eliminate the guesswork when planning your DIY repair.

Common Symptoms of a Bad Thermostat:

• The engine overheats quickly or the dashboard temperature gauge spikes into the red zone (thermostat stuck closed)
• The engine takes an unusually long time to warm up, or never reaches operating temperature (thermostat stuck open)
• The check engine light comes on (frequently with code P0128 for coolant temperature regulation)
• Erratic cabin heater performance, switching randomly between hot and lukewarm air
• A sudden drop in fuel economy as the engine struggles to run at its optimal temperature

Safety First

Always prioritize safety when working on your vehicle’s cooling system. You must ensure the engine is completely turned off and cool to the touch before loosening any bolts or hoses; a hot cooling system is highly pressurized and can spray boiling fluid, causing severe burns. Protect your eyes and skin by wearing safety glasses and fluid-resistant work gloves, use a proper drain pan to catch escaping coolant, and maintain full focus on the job.
