The car engine is designed to operate between 90 and 110 degrees Celsius. When the engine runs at the specified temperatures, parts such as the piston sleeve expand for optimal performance.
Without a thermostat, a car engine may not reach the appropriate temperatures, especially during the cold winter months. If the engine does not heat to at least 90 degrees Celsius, driving the vehicle wears down the parts faster.
