In this video, I show you the exact location of the engine Thermostat assembly on a 2016-2019 Chevrolet Cruze equipped with the 1.4L turbocharged engine. Finding exactly where this housing is on the vehicle is an essential first step for a successful DIY diagnosis or repair, saving you time and guesswork before you start draining any fluids.
Common symptoms of a faulty or stuck Thermostat include:
- The engine overheats quickly, with the dashboard temperature gauge climbing into the red zone, often triggering a “Engine Overheated – Idle Engine” warning message.
- The engine takes an unusually long time to warm up, or the temperature gauge drops down while driving at highway speeds, meaning the thermostat is stuck open.
- An active Check Engine Light (CEL) on your dashboard with specific cooling system performance codes, most notably trouble code P0128.
Safety First: Engine coolant operates under high pressure and reaches scalding temperatures. Never attempt to work on the thermostat housing, remove hoses, or open the cooling system until the engine has sat completely shut off and is cool to the touch. Always capture any escaping fluid in a proper drain pan, protect your hands and eyes by wearing durable gloves and safety glasses, and stay fully focused and attentive throughout the entire process.
