How does a car thermostat work? The thermostat in your car is actually an important component of your car's cooling system. Basically, its job is to regulate how much coolant is circulated back into your engine and how much is refrigerated through the radiator before being returned to the engine. The temperature of the engine and your battery are regulated by this thermostat. Once you start a cold engine, a valve (thermostatic valve) is opened, permitting the coolant around the engine to regulate the correct working temperature. It uses a wire that senses the temperature of the fuel and opens a sensor to allow only the specified amount of heat to be conducted through to the block. As the engine cools while running the temperature of the fuel decreases, and the sensor detects this change and opens a metal channel to allow the heat to flow through to the block. As the temperature of the fuel continues to decrease the channel is forced open slightly as more heat is allowed to flow th ... read more
