What temperature does a 160 degree thermostat open?

A 160-degree thermostat is designed to open at approximately 160 degrees Fahrenheit. This means that when the engine coolant reaches this temperature, the thermostat will begin to open, allowing coolant to flow from the engine to the radiator. This helps regulate the engine's temperature and prevents overheating. It's important to note that the actual opening temperature can vary slightly due to manufacturing tolerances.
