Car Engine Overheating can be a big issue and can render your car useless if not addressed properly. Overheating engines can be caused by multiple reasons ranging from the problem related to the cooling system to leaks in any part of the vehicle.

It is important to note that this problem of overheating engines is not so common with modern vehicles, however, there are still chances that you might face this issue. Here we have mentioned some reasons which can be at the root of the overheating issues of your vehicle.

Signs of overheating cars

If your temperature gauge begins to climb or a malfunction light illuminates, you may have a problem with your automobile overheating. You might also notice vapour coming from the hood or a smell coming from the engine.

What causes a car engine to overheat?

It might be highly dangerous if your car overheats. When your car’s air conditioner stops working, it’s a symptom that it’s overheated. Your automobile may not explode or anything if your engine overheats, but driving with an overheating engine can cause major harm to your vehicle. It’s preferable to pull over and deal with it right away rather than risk costly repairs later.

Overheating in your car can be extremely dangerous.

The failure of your car’s air conditioner is one sign that it is overheating. If the temperature gauge has shifted to the “hot” side, you should not continue driving. Your car may not explode if your engine overheats, but driving with an overheated engine can cause serious damage to your vehicle. It’s better to pull over and deal with it now rather than risking costly repairs later.

A number of factors can cause your engine to overheat. Some of these are fairly common issues on a hot summer day.

Incorrect Coolant Circulation

The engine will begin to overheat if the water/antifreeze mixture is not properly circulating. This mixture keeps your engine cool in hot weather and keeps it from freezing in cold weather. To avoid this, ensure that you check it on a regular basis. Even if you don’t have any leaks, they can evaporate over time. To cool down your engine and get you to an auto shop, add half a cup of water to a low antifreeze tank.

There is a leak

If your water/antifreeze levels are constantly low, there’s a leak somewhere in your cooling system. If this is happening to you, please contact us right away. We’ll locate the leak and provide you with a reasonable repair estimate.

A hose must be replaced

The hoses that circulate your coolant may become clogged or detached over time. While it may not be completely blocked, even a partial blockage can prevent adequate coolant circulation. Again, we can check for this during an inspection here in our shop.

Oil Shortage

As you are all aware, oil is used to lubricate and somewhat cool the moving parts of an engine. Whether it’s a gasket leak or a sealing issue within the cylinders, oil can seep through to places it shouldn’t or be burned during combustion, giving the emissions a blueish tint. This means that the lubrication system is deficient in fluid, resulting in increased friction within the engine and heat buildup.

This heat energy accumulation can exceed the cooling system’s capacity and, if unnoticed, can lead to an engine literally welding itself together, potentially seizing the pistons. If that doesn’t happen, something else will inevitably blow because of the heat, potentially tearing a hole in the engine block.

Other Factors

If the levels of water and antifreeze appear normal, your engine may be experiencing a more serious problem. There could be an internal coolant leak, debris in the coolant passages, or a clogged radiator. In this case, you should take your car to a mechanic as soon as possible. We can identify problems that will save you money on future repairs.

What should you do if your engine is overheating?

Pull over to the side of the road and open the hood. This allows heat to escape and air to flow through the hot engine. When you open the hood, take care not to let hot steam out.

Turn the heater on. This allows some of the engine’s excess heat to escape into the vehicle. While it isn’t ideal on a hot summer day (when most automobiles overheat), it does assist in cooling the engine.

The air conditioner should be turned off. The A/C puts a lot of strain on your engine.

Can you drive with engine overheating?

  • Can I pour water on my engine to cool it down?
  • How do I cool down my engine fast?

How do I fix my car from overheating?

Place your automobile in the park or neutral, then rev the engine. This causes the fan and water pump to spin faster, pulling more air and water through the radiator. The engine cools down as a result of the increased circulation.
