It can be difficult to know what temperature your car’s engine should be operating at. Too high of a temperature and you risk damaging the engine; too low of a temperature and you might not get the most out of your car’s performance. In this article, we’ll explain the different temperatures that your car’s engine can operate at, and what regulates them.
The Thermostat
The thermostat regulates the car engine temperature. It is a small, metallic device located near the engine and uses a built-in thermometer to measure the engine temperature. The thermostat opens or shuts the valves in the cooling system to keep the engine at a safe operating temperature.
The Engine Coolant
The engine coolant regulates the engine temperature by dissipating heat from the engine. The coolant is composed of water, ethylene glycol, and antifreeze. The cooling system sends a constant stream of cold water to the radiator to keep the engine at an optimum temperature.
The Fan
The fan regulates the engine temperature by pulling air over the engine and distributing it evenly. The fan also helps to circulate air throughout the car, preventing heat buildup.
The Radiator
The radiator is a large, fins-shaped device that sits on the engine block and absorbs heat from the engine. The radiator works in conjunction with the fan to circulate the air around the engine.
The temperature of the radiator depends on a few factors, including the engine’s RPM, load (the amount of weight being carried by the vehicle), and ambient temperature. When it gets too hot for the radiator, the fan starts up to help move air around the engine.
Conclusion
The car engine temperature is regulated by the thermostat, which uses the coolant to control the engine temperature. The thermostat senses the internal temperature of the car and opens or closes the radiator valves in response.
