When your check engine light illuminates, it is often the first sign of car trouble. There are various reasons why your car's check engine light could come on, from a loose gas cap or faulty chip to a blown head gasket or something much worse. But when it comes to your engine overheating, there are 5 probable causes behind the problem. And the signs are not hard to see.

One of the first signs of an overheating car engine is usually seeing the temperature gauge nearing or exceeding the maximum internal engine temperature level illustrated on the dial. But most often, you just see smoke coming from the hood! You might also smell burning oil or fuel, which is another sign of your car engine overheating. Continue reading to learn five likely reasons why your car engine is overheating.

Radiator Issues

There are two common radiator defects that can lead to a car engine overheating. First, you could have a bad radiator fan. This fan blows air over the radiator fins in order to help control the temperature of the coolant. If it comes loose, has broken shrouds, or spins freely when the engine is off, it cannot perform its intended duties, causing the coolant temperature to rise and overheat the engine. But if the fan is not the problem, it could just be a faulty radiator. Leaks, clogs, and broken lines can cause a radiator to malfunction, and subsequently, cause a car engine to overheat.

Cooling System Issues

A vehicle's cooling system lines can get blocked or clogged with rust, dirt, or sediment. This inhibits the cooling system from being able to do its job, thus causing the engine overheat. This is why regular fluid flushed and replacements are imperative. Another common cause of an overheating car engine in terms of a vehicle's cooling system leaks. Leaks in the cooling system are a frequent cause for overheating car engines. Also, if you use the wrong concentration of coolant, it can have the same effect. Be sure to get an even water-to-coolant ratio.

Thermostat Issues

A bad thermostat is another common reason for overheated car engines. It is a heat-sensitive valve that opens and shuts in accordance with engine temperature. If something goes wrong and the thermostat gets stuck in the closed position, the car engine's temperature will skyrocket.

Water Pump Issues

The water pump is colloquially known as the "heart" of the vehicle since it pumps coolant much like a heart pumps blood. But a vehicle's water pump pressurizes and propels coolant through the cooling system, so it plays a major role in a car's temperature control. If something goes wrong, the coolant can't make it to the engine, and the engine gets too hot.

Belt and Hose Issues

Broken and loose belts, as well as, worn or burst hoses, are common causes for overheating car engines. Belts turn the water pump, which is essential for the cooling system and more. If they stop working, so does the cooling system. A faulty hose means leaks, which means a lack of coolant. This also causes a car to overheat.

I don't own a car yet

But for those who are like me that doesn't own a car....

Look no further than my signature

Nice piece

but, any idea on how to correct overheating?

My car started over heating since I change the compressor and condenser. Once I turn d AC on it's start over heating. Please what can be d problem.

I've heard.

AC compressor is an extra load on your the car system and thereby increases the pressure on your cooling system .I am sure your cooling system is already tropicalized to cover up for previous fault. .
Flush your radiator if clogged with dirt and if the symptom still persist see a car professional for a cooling system pressure test .
Finally if the issue has been resolved. don't forget to revert to default to avoid another round of overheating.

No be person we get car dey think of over heating?

Nice write up.

I have been having issues of overheating with my chrysler car.just within a very short distance the car will start to overheat.This is an embarasment and leaves me sad.

good topic.
on the thermostat issue... . I just removed the thermostat on my sienna 2002. The fan now comes up immediately I put on the engine.. because It only comes up only when I put the AC... I hope no problem.. make una help me oooo

Bro yu just sent the car to heaven by removing the thermostat I did same to my Nissan quest 2000 before I knew I took a wrong decision. I'm sure its your first car that's why Kabiru gave u wrong instruction

Oga Gazzuz tell this brother more

Thanks for sharing

What you have just done is more like paying somebody to destroy your car.
This is what you will stand to gain as a result this abuse : Higher fuel consumption,Alternator is susceptible to failure , poor lubrication ,destruction of catalytic converter might cause exhaust restrictions ,engine will soon start smoking soon !!
You need to revert to default ASAP before car start behaving as if your village people is at work !!

My car often indicate on the dashboard that I fill-in water coolant. it gets frequent that I normally put just water to save cost. All this happened when I noticed a very little leak at the top of the radiator. A mechanic had to loosen the whole radiator and applied strong adhesive glue at the little leak. There isn't any leak now, how come it frequently requires coolant/water ? I need an advice on what to do. its a Mercedes car E-Class.

How often do u top the water up in the Radiator !!

honmusa:

once in a week, Before, it takes months.

victor101:

The level of water must not go down at all even for a year unless there is a leak .So there is a leak .

seems the thermostat has been removed

Haha bro.


So for a whole 365 days, the water in the radiator will not go drop, hence no need to even check it regularly except there is a leak.


I beg to disagree Sir.

Hello Op... nice post you have here. Now you have given causes of overheating, I was hoping you'll also give us resolutions to these overheating causes.
I have a crv (99) that is overheating. If one drives below 80KM/hr, overheating wont happen unless one is stuck in traffic. But if I drive above 80Km/hr, that is when I experience overheating. The coolant/water dries out. What do you think could be the cause of this?
