The 2012 Chevy Traverse's thermostat is located in the thermostat housing on the lower coolant line. The thermostat is responsible for monitoring the coolant temperature as it flows through the line, helping to determine the engine's operating temperature. If this component malfunctions, it could lead to the engine overheating, which can cause significant damage to the vehicle. An overheated engine may result in the head gasket warping or cracking, leading to expensive repairs in the future. If you receive a check engine light indicating thermostat issues, it's crucial to address the problem promptly. A full replacement typically costs around $200, so delaying the repair is not advisable.
