Car Overheating

Car overheating can be a significant problem a driver faces most time, and it frustrated and scary to see smoke coming out from your engine.

This issue mainly occurs during summertime as we know that everywhere gets dry, the temperatures are rising while the risk of your car overheating is on an upward trend.

Overheating engines do happen, and the damage can be permanent if care is taken. When engines run too hot can easily cause damage and spoil your journey during that moment.

Maybe you are stuck in traffic, and all of a sudden, your temperature gauge is high. It means your car is overheating, and you need to find a solution before it gets out of hand.

Another thing is that if your car is baking in the sun at around 90 to 100 degrees while the engine hasn’t been turned on. Then you are at a disadvantage period.

More so, various external temperature factors can contribute to your car’s risk of overheating, but the thing is most are preventable if you have an idea of what to look for.

Make sure to check your car engine and some other thing before you drive for a summer trip.

Basic fact

Whenever you are driving and you notice your vehicle is overheating, don’t drive farther. What you need to do is pull over and stop the car.

What does a cooling system do?

Before we go into why car engines can begin to overheat, it is imperative to know what an engine’s cooling system does.

The cooling system is meant to keep a standard temperature for the engine by circulating coolant or antifreeze via the engine to the radiator, pulling heat away from the car engine without much problem.

What occurs when an engine overheats?

Most cars nowadays are built to be durable. By the time heat started generating from the vehicle, then is above the average operating temperature.

The devices create to cool this heat distribution may begin to fail.

The engine can be damaged, and even the gaskets, hoses, and seats are made to keep the engine running.

A vehicle can overheat in various ways, like blocked hoses from corrosion, cooling system leaks, mineral deposits, broken water pumps, and radiator problems.

Note that frequent service and inspections may assist in avoiding overheating problems down the road.

Steps to reduce the potential damage to your car


Before we narrate the causes of the car’s overheating, let’s talk about the potential damage to your vehicle until you get it into a nearby auto service shop.

  • First, turn off your car AC immediately.
  • Then instantly on your defroster and your heat to the hot, fan on high.
  • We all know that it won’t be comfortable until you get your car off the road during summertime, but having it in mind that stopping your car is better than spending thousands of dollars if your vehicle keeps overheating. Roll down the windows too, because it is going to be hotter inside your car also.
  • If you get stopped in traffic, make sure you put your car in Neutral and raise the engine speed high. It means that you are trying to get the coolant circulating as much as possible.
  • If the car is moving, albeit slowly and put the car into the lowest gear to continuec between 2 or 3 on the RPM gauge to pull over to a good spot.

The information above should help get your car temperature gauge headed back down temporarily. But if nothing happens to get the lower temperature in about 2 minutes, then shut the car off immediately.

Six possible reasons for car engine overheating. 

Check the common factors that may cause a car’s engine to overheat:

Leaks in the Cooling System

The number one reason for overheating in the vehicle is leaking in the cooling system and leaks in hoses.

The radiators, thermostat housing, water pump, head gasket, heater core, freeze plugs, and other things can lead to an issue with the vehicle’s cooling system.

If you notice a leak or even add coolant to the reservoir, never wait to get it checked. 

A small leak in your car can quickly turn into a bigger thing and can be expensive to repair.

A little or no coolant

System failure can quickly occur while driving without proper levels of coolant or antifreeze. Refill or top of the levels if coolant levels are decrease than the manufacturer’s recommendation.

Information notice about it is that, when refilling new coolant to an empty reservoir, make sure to use only a 50/50 mix of antifreeze/coolant and water. 

Then if you are unsure where the coolant reservoir task is located, kindly refer to your vehicle owner’s manual.

Bad thermostat

Many things work together and for a car to work perfectly. Do you know that your car thermostat stands as a vital valve in the cooling system that ensures the coolant can pass through to the radiator when needed?

Whenever the thermostat gets stuck in the closed level, your car coolant can no longer pass through and becomes overheated in the engine.

If radiators go wrong

If the radiator stops working, then your vehicle may not function because it is responsible for cooling down the engine coolant as it passes through.

Which means that good radiator function is essential to maintaining the engine temperature.

Remember that whenever your car radiator is causing your engine to overheat, the first thing to check is your radiator fan and other parts. 

Another problem is if your fan is not working perfectly due to a broken fan blade, it can also prevent the radiator from reducing the coolant temperature adequately.

If the fan’s engine may also spin, it probably won’t help when it comes to keeping things cool.

Low oil stage problem

The benefit of oil in a car is that it helps with the cooling process and avoids excessive heat buildup. 

Having good oil can also make different parts of the engine properly lubricated, reducing friction and overheating. If your car oil levels are low, then your car can begin to overheat.

Problems with the belts and hoses

The purpose of belts and hoses in the car has a good outcome, but if the hoses are leaking, ruptured, or blocked, and the belts are worn out also, the engine system will be limited and may even lead to unexpected engine damage.
