* Radiator: This is the largest component and sits in front of the engine, behind the grille.
* Engine coolant reservoir: A plastic tank usually located near the radiator or on the side of the engine bay. This holds extra coolant.
* Water pump: Located on the engine itself, it circulates coolant through the system.
* Thermostat: Also located on the engine, this regulates the coolant flow to maintain optimal temperature.
* Fan(s): Typically located behind the radiator, these help cool the radiator when the vehicle is stationary or at low speeds.
* Coolant hoses: These connect all the components together.
To be precise about a specific location you'd need to consult a repair manual or a diagram specific to your Traverse's year and engine. The layout might have minor variations between model years.
