Car Overheats

An overheating engine is not something you should put off attending to, regardless of what may have caused the problem.

We’ve all seen it: a motorist stuck somewhere in the middle of nowhere, looking confused as their vehicle begins to slow down and smoke. It’s possible that you were even there yourself. There are many potential causes for your automobile to reach an unsafe temperature. This happens during the middle of the year in temperate climates the vast majority of the time. Even though there are ways to prevent this from occurring, even the most high-tech automobiles have a propensity to overheat at some point. This is one possible explanation for what is going on.

What Happens When A Car Overheats?

1. Your motor coolant is low

The fluid refrigerant in your vehicle is almost certainly to blame for the overheating that has been occurring in your vehicle. The majority of contemporary automobiles make use of a liquid cooling system, whereas the majority of older automobiles rely on air conditioning.

Your vehicle’s coolant, also known as a liquid catalyst, is responsible for absorbing heat in order to prevent the engine from overheating. It has a low point of solidification and an extremely high breaking point, which enables it to retain the highest possible level of heat. The cooling system in your vehicle makes use of pressure to raise the freezing point of the water to a substantially higher level (similar to how the freezing point of water is raised in a pressure cooker).

This liquid travels through the various channels and pathways of your engine, and as a result, the liquid cools the most essential components. It passes through a radiator, and the heat that was contained in the liquid is transferred to the air that is surrounding your heat exchanger.

In the event that you are running low on refrigerant or that your engine hasn’t been cooled in a considerable amount of time, it is possible for it to overheat and even seize up. When the temperature of the metal reaches a certain threshold, the cylinder will be able to self-weld itself into the cavity. This most likely demonstrates that the damage to your engine is extensive.

2. Broken holes in the cooling system

There are a few signs that indicate you will be coming into contact with a coolant discharge. You may have noticed that the level of coolant in your repository tank is lower than it should be, or you may have smelled or seen a puddle of coolant forming underneath the vehicle.

If the top of the radiator is fractured or if there are holes on the inside or the outside, coolant can leak out. If you observe that the amount of your coolant does not remain consistent, one of the potential causes could be an interior break. On the other hand, there are no outward indications to be found. Simply peering under your vehicle will reveal whether or not there is a break on the exterior.

3. Broken thermostat

If you are able to find a method to cool your motor before it overheats to the point where it stops working, you can reduce the risk of causing irreparable damage to your motor.

Your indoor regulator is an important valve in the cooling system that ensures the refrigerant can pass through to the radiator when it is required to do so. In the event that the indoor regulator becomes stuck in the closed position, it is possible for the refrigerant to pass through and cause the engine to become overheated.

It is a good idea to have your automobile checked out as soon as possible if there are any indications that it may be overheating. As a result, making any conceivable essential repairs will not be a significant challenge.

4. Low engine oil

The engine oil helps eliminate the warming that is produced by your motor and reduces the grinding and wear that occurs. Additionally, it assists in maintaining the metals’ lubrication and removes other harmful contaminants. If it’s significantly lower than it should be, this can cause your engine to heat up more quickly than usual.

5. Terrible water pump

The water siphon is the most important component of your refrigeration infrastructure. In the event that it is not operating properly, your vehicle needs to be put under a sufficient amount of pressure to transport motor coolant all through the cooling structure. Any problem with the siphon, whether it be flaws, disintegration, or something else entirely, can cause your vehicle to overheat.

6. Exhausted or burst hoses

Hoses that are broken or even just have gaps in them will cause the coolant stream to become erratic, which will result in a cracked engine. Because some of the coolant has leaked out of one of the tubes, your water siphon won’t be able to complete its cycle.

What to Do When Your Engine Overheats

Car Overheats

We tracked down the developers of vehicle cooling systems to find out what happens to engines when they get too hot and what people can do to help prevent their vehicles from breaking down.

1. Kill the A/C and wrench the warmth

As soon as possible, switch off the system that uses forced air to reduce the load on the motor. At that point, move the dial all the way to the right to achieve the highest level of warmth. This can help you draw with continuous heat from the engine, which can protect it from overheating until you can pull over in a safe area.

Even though you might feel uncomfortable for a few minutes due to the heat, you should consider the alternative of spending a substantial amount of money on major auto repairs.

2. Look for a place with some cover to draw over.

Stop in a safe place and turn off the engine. Allow the engine to cool for at least fifteen minutes before proceeding. Keep an eye on the temperature measurement, as it ought to return to the typical range as the engine returns to its normal operating temperature.

During this brief pause, you should make plans to have the overheated engine checked out by a professional. Help can be summoned by calling a friend, a tow vehicle, or the local roadside assistance service.

3. Make sure you include the refrigerant. (if you have it)

If the level of coolant in your vehicle is low, quickly adding more could help protect your engine and prevent it from overheating until you can get the problem repaired. On the other hand, this progression won’t do much good if a coolant pipe is clogged up or if the source of your problems is a broken radiator fan or water siphon. In those cases, the progression won’t be very helpful. Consult the owner’s handbook of your vehicle to ascertain the location of the coolant storage tank as well as the procedure for topping off the coolant in your vehicle.

4. Turn the engine back on.

If your vehicle is not being towed, you have the option to purposefully restart your engine and travel to the nearest auto repair shop at this time. While you are driving, keep an eye out for the temperature measurement. If it rises again, pull over and let the framework settle down before continuing.

5. Keep your calm

If you don’t have emergency assistance, be patient. The minimum amount of time required for the engine to cool down is fifteen minutes. While this is going on, you shouldn’t even attempt to raise the hood because the coolant in a vehicle that has overheated could be hotter than 230 degrees. If you leave the shade open, there is a possibility that you will be scalded by scalding water or steam.


If you take good care of your vehicle, it will reward you by giving you reliable transportation. Maintaining your radiator in accordance with the guidelines provided by your vehicle’s manufacturer is the most effective way to reduce the risk of your engine overheating. This includes having your vehicle’s radiator flushed and replaced at regular intervals. Regular inspections can also help you identify and resolve potential problems with the condenser or the engine before they become more serious.
