Engine Coolant Thermostat Kit

The ACDelco 131-160 is a GM Original Equipment engine coolant thermostat kit, engineered to provide the same performance, durability, and service life expected from factory components. This kit includes the thermostat and the necessary gasket to ensure a complete and proper installation. Its primary function is to regulate the flow of coolant through the vehicle's radiator, thereby enabling the engine to reach and maintain its optimal operating temperature. It is a GM-recommended replacement part, manufactured to exact GM OE specifications, ensuring a precise fit, form, and function. The thermostat is designed to operate at 187 degrees Fahrenheit, contributing to efficient engine performance and fuel economy. A properly functioning thermostat is crucial, as a damaged one can lead to engine overheating or reduced fuel efficiency (potentially 10-20% more fuel consumption if the engine runs too cold). Signs of a failing thermostat can include coolant leaks, engine overheating, lack of interior heat in the cabin, or reduced fuel economy. Regular maintenance of the cooling system, including proper coolant levels and inspection of related components like hoses and radiator caps, is recommended. This ACDelco thermostat, along with its included gasket, offers a reliable solution for maintaining your vehicle's cooling system integrity.
