The system consists of a water pump, thermostat, radiator, radiator fan and plumbing which sends water and coolant mixture throughout the engine. This system is designed to maintain the ideal working temperature of 190 Fahrenheit no matter the outside temperature.

How many temperature sensors does a car have?

Some cars have two temperature sensors, while other car models have one. The models with one sensor usually both use the engine control unit’s temperature and the same sensor for the gauge. If your car model has two coolant temperature sensors, one is used by the temperature gauge, and one is used for the engine control unit.
