7 Warning Symptoms Of An Overheating Car

Car engines don’t remain cool all the time. Poor lubrication, for instance, can cause them to heat up quickly. Of course, you would want to arrest this problem right away before it becomes too difficult and expensive to handle. 

If you think that the engine of your car is overheating, it is better that you should not check its cooling system. Doing so will put added pressure into it, which, in turn, can cause burns. If there’s an issue, let the engine cool down first. 

Meanwhile, these are the symptoms that your car is surging hot already. 

Temperature Gauge

Most modern vehicles have a warning light on them that specifies the temperature of the engine. Usually, these engine lights don’t switch on unless the engine has already reached extremely hot temperatures. If the gauge is already at the top, the heat is already excessive. But sometimes, you need to assess things properly. There are cases where there are no signals being picked due to the leaking of coolants. 

Burning Smell

Your car is a running piece of combined metals. But it also has plastics, rubbers, and fluids. If the engine is already hot, these non-metallic parts will be affected by the heat. Aside from getting hot, they will emit a burning scent, which is understandable, by the way. Even if the temperature gauge is not raising signals, you still need to pull over your vehicle if you are already smelling this scent. The fumes can come through the AC vents. After all, the engine is just adjacent to the air intake of the HVAC system. 

Ticking Noises

The engine oil is an essential lubricant. It serves as a protective coating to the moving parts of the engine so that they can grind each other without causing friction and grinding. If the oil is hot, its lubricating capability is eventually lost. The oil becomes like water–it will lose its weight. When this happens, the engine will begin to tick. It signals that the lubrication in the engine has diminished already. 

Leaking Coolant

The coolant should stay inside the vehicle. It is not supposed to drip off to the ground. Once you notice that there’s a liquid coolant in the ground where you parked your vehicle, it is a sign that the engine of your vehicle is overheating. Of course, one of the reasons for this is the leakages in the cooling system, which have caused the engine to become hot. It could also be due to the boiling of the coolant inside the cooling system. 

Visible Steam Or Smoke

You can easily know if the coolant is boiling. There is steam that comes out from the hood. The fumes will escape on the front, rear, or sides. Coolant boils like water, which is an indicator that the engine is already way too hot. Of course, if you see the steam, you need to pull over right away. Otherwise, serious damages will be incurred, and you will have to deal with extensive repairs and replacements. Sometimes, it might even force you to get a new car. 

Weakened Engine Efficiency

Engines work best if they are not hot. They are designed to run at an optimal temperature–that’s far from being hot. When it has gone above the normal temperatures, the engine will not work correctly. Its power will be reduced. The pistons that are inside the cylinder bore will slow the crankshaft rotation drastically. Again, such a condition is caused by excessive heat. Therefore, if you notice that your vehicle is losing power, that’s a probable sign that your engine is already hot. 

Hot Hood

Do you really want a surefire method of knowing if your car is hot or not? Try touching the hood. Always keep in mind that the hood of the vehicle does get hot–but not a scorching level. You should still be able to touch it. An excellent test to conduct here is by putting your hands in the hood for ten seconds. If you can deal with it, then the engine should still be at the right temperatures. But if you can’t endure the heat, then that’s a warning sign already. Pull the vehicle over and wait for a couple of minutes before checking if that’s really the case.
