![]() ![]() This boiling coolant will cause steam to come out of it. If you have a faulty radiator and the coolant isn’t able to cool down, then it will start to boil. This can be attributed to the hot coolant.

But if the needle is in the red area, this indicates that you have an overheated engine. In normal situations, the needle of the gauge will be in the black area. This gauge is supposed to tell you the temperature of the engine. Your vehicle should have a temperature gauge on the dashboard. If you notice at least a few of these symptoms present in your vehicle, then you should act fast and resolve the issue before it is too late. 5 Common Symptoms of Engine Overheatingīelow are the top 5 symptoms of an overheated engine. This can ultimately result in overheating and internal engine damage. If your engine has too low of an amount of oil (or old oil that’s deteriorated enough), excess friction will be the result which drastically raises the engine temperature. Related: Different Types of Coolant (and Their Colors) #6 – Low Engine OilĪs stated earlier, motor not only acts as a lubricant between the moving components inside an engine, it acts keeps internal temperatures at bay. The best thing you can do is flush your entire cooling system and then add the right cooling fluid back into the system. If you put new coolant fluid in your vehicle recently, then perhaps you used the wrong antifreeze (or an internal oil leak is mixing with coolant). You might not see any leaks or faulty components at all, but still notice your engine overheating. Other times, there are leaks or clogs in the radiator or even a faulty radiator cap. Sometimes a radiator might have a broken fan which prevents the hot air from escaping. This means the engine is going to stay hot as well. If you have a bad radiator, the coolant liquid is going to stay hot. The radiator is what transfers heat out of the hot coolant so that it can cycle back into the engine and cool it down again. Check the impeller vanes or bump shaft because these are commonly the reasons for the water pump going bad. ![]() If the water pump is damaged or worn out, your engine will overheat from it. The water pump is the component which propels the coolant fluid so that it can flow in the cooling system.

This will block the coolant fluid from being able to flow through the system properly. This might happen if sediment or dirt from the road inadvertently got into the hose. If your engine is overheating but there is no coolant leak, then you might have a clogged coolant hose. If the leak is small, you might be able to temporarily patch it up until you have time to bring your vehicle to the shop and replace that component. This will result in an overheated engine. If any of these components gets damaged or worn out, they might leak coolant out from them. You have a water pump, radiator, thermostat, hoses, and a head gasket that make this all happen. There is an entire cooling system which keeps the coolant flowing smoothly. Your engine depends on coolant to stay cool as it is running. It is better to do this sooner rather than later or else your engine might never function the same again. ![]() Once you understand these common causes, you will know where to look so that you can fix the cause of the problem right away. 5 Common Symptoms of Engine Overheatingīelow are the top 6 causes of an overheated engine. ![]()
