![]() This causes Engine Coolant Temperature fluctuation as enough coolant no longer circulates back to the engine. Check the coolant temp and level is necessary to maintain the system in good shape.Ī coolant leak causes a reduction in the amount of engine coolant available in the car system. Low coolant levels within your car engine system could increase friction which causes an unnatural increase in temperature. That also causes engine overheat, which can lead to high temperature coolant. If it’s been awhile since your last coolant change and your engine coolant has dirt contamination even in a small amount, it may not cool an engine properly. Here are the significant causes of Engine Coolant Temperature fluctuation. Temperature Gauge Lower or Higher Than Normal.Here are some signs to alert you if your engine coolant temperature fluctuates. This is very dangerous for the cooling system because it can damage some certain parts of your car. Then the coolant temperature won’t stay stable. Over time, under severe working conditions, the coolant and some parts in the cooling system will be damaged. Preventing corrosion ensures regular system thermal performance and a continuous, normal flow of engine coolant. This is because a mix of water and glycol solution can cause corrosion at the wrong temperature. Knowing the engine coolant temperature allows you to estimate the actual state of the engine coolant. However, once you can estimate the temperature of your engine coolant, you would take the required steps to prevent further damage. It will be unsafe to drive your car around. Overheating could cause engine cracks which cause significant oil leaks and low performance. While you may love summer road trips, you should ensure your car engine remains cool. Help protect the engine from the summer heat That way, your coolant remains unfrozen and allows your engine to run efficiently. So, if the coolant temperature is below freezing point, you would take urgent steps to top up. ![]() However, you can avoid this by knowing the proper coolant temperature for your car engine. If the coolant freezes, the radiator will be damaged, as well as the engine. Prevent the coolant from freezing during the winter Let’s see why ECT is important to the cooling system: In addition, there is also a sensor that you can use to monitor the optimal temperature for your car engine. 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? ![]()
