Find Out About Sudden Causes of Engine Temperature Rise in Your Car


Have you ever seen a car's temperature indicator go up and down randomly? This condition is often troubling, especially if you don't know the cause. Conditions in which the temperature of the vehicle heats up quickly should not be left un-notice, if not corrected immediately, it could damage the vehicle's engine. Here are some of the causes of a sudden rise in temperature in a car.



By its purpose, the oil is a lubricating fluid that ensures trouble-free operation of the engine. The oil acts not only as a lubricant, but also as a coolant and insulator in the engine room. The thin layers contained in the oil fluid serve to minimize friction between metals and engine parts. If you are using the wrong oil or oil that is not of good quality, the temperature of the vehicle can rise sharply. If low-quality oil used, cannot withstand the high temperature of a car engine, the oil will evaporate quickly. When the oil evaporates, the lubrication in the engine compartment is automatically reduced and the metals in the engine compartment rub against each other without lubrication. The engine heats up due to friction between metals.


Car Radiator Condition:

A radiator is a component that is used to cool the engine and cool the water in the engine so that the engine can run normally. The heat generated by the engine is absorbed by the radiator fluid or coolant, which circulates through the water jacket in the cylinder and cylinder head. This hot fluid is then pushed to the radiator and flows back through the engine. When the radiator condition is not optimal and the temperature in the vehicle rises. If, for example, the hose connected to the radiator leaks, gets jammed and crusted, the cooling circulation is impeded and cause the engine to heats up.


Radiator Water:

The choice of water for the radiator also affects the car's temperature. Many people do not realize the importance of what kind of water in a radiator is good. Most people only use well water, ground water, and regular mineral water, all three of which contain metals and minerals that can cause engine blockages. Therefore, you'd better immediately replace the water in your car's radiator with a special coolant.


Coolant Leaking:

The next reason for the car's temperature rise is a leaky radiator. Radiator leaks are usually caused by corrosion of the radiator grille. This is because the radiator is not filled with radiator water (coolant). Oxygen in the water enters the metal and a chemical reaction occurs that causes corrosion. This corrosion will destroy the metallic body of radiator and cause leaks. This leakage wastes coolant, so there is not enough coolant to cool the car engine. If the coolant does not cool the engine for a long time, the vehicle temperature rises rapidly.


The Radiator has Run Out of Water:

The most common cause of a car's temperature rise is water leakage from the radiator. Radiator water (coolant) can escape due to evaporation at high engine temperatures. Or there is a leak in the refrigerant circuit. This can result in the refrigerant circulation system not performing optimally. If the cooling water becomes too low, the temperature in the engine cannot be reduced. Then the car engine overheats.
