The same is true of your car’s internal combustion engine, which needs to cool down when it gets hot and vice versa.įor this reason, several cars have coolants embedded in their internal combustion engines. Why Is Engine Coolant Temperature Important?Īs humans, our bodies possess a mechanism that helps us control internal temperature relative to our environment. Thanks to a water pump, your car’s coolant can move freely through the hidden passages. After cooling, this engine coolant recirculates back into the engine compartment, and the process repeats itself. That way, the coolant picks up heat as it flows through the engine passages.įurthermore, the heated fluids go to your car radiator and are cooled by air entering the engine compartment. So, whenever your engine heats up, the cooling system sends the engine coolant through the engine block and head passages. Here’s how an engine coolant works in an internal combustion engine. ![]() The water component enables proper absorption of heat while antifreeze increases the boiling point. Some are made from propylene glycol and do have a varying color of green, blue or pink… Besides, the overall coolant contains distilled water and antifreeze at a 1:1 ratio. However, not all engine coolants are the same. And, ethylene glycol is responsible for the antifreeze properties of any coolant you buy from a marketplace. For context, this fluid comes with a chemical substance known as ethylene glycol. This article will show you what engine coolant temperature is all about and ways you can check it.Įngine coolant (also known as antifreeze) comes as a fluid that allows your engine to operate at optimum temperature. However, how seriously should you take your engine coolant temperature? ![]() That way, you will know if your internal combustion engine runs at an optimal temperature. Do you know that the engine coolant temperature helps measure the degree of hotness or coldness of your car’s internal combustion engine?
