Why Does My Car Overheat?

Is your vehicle overheating? Don’t worry! This article will discuss the potential causes and provide five simple solutions to get your car running again in no time. Continue reading to learn more about identifying the issue and preventing it from recurring.

How to Identify Overheating

There are a few obvious signs that your car is overheating. 

  1. if the temperature reading on your dashboard begins to move into the red zone. 
  2. Steam or smoke from beneath the hood is another sign that indicates that your car is overheating. 
  3. you may also smell burning coolant if your vehicle is overheating.
  4. Stop and shut off your engine
  5. Then, open your vehicle’s hood to allow the heat to escape. Check the radiator water level once the engine has cooled down, and top it up if required. 
  6. Use water as a temporary coolant until you can reach a service station.
  7. Calling a tow truck or roadside help is recommended if your automobile won’t start after it cools down. 
  8. Your engine might be damaged by overheating. Thus it is better to be cautious than sorry!

Common Car Overheating Causes

Vehicles overheat for several reasons. However, the most prevalent are:

Low Coolant Levels

If the coolant level in your car’s radiator is low, it won’t be able to cool the engine effectively, which might result in the engine overheating.

Leaks in the Cooling System

Leaks in the hoses or other components of the cooling system may also result in low coolant levels and engine overheating.

Radiator Issues

A defective radiator may lead to an overheated engine. There may be a clog preventing coolant from flowing through the radiator, or the radiator may be unable to disperse heat effectively.

The thermostat regulates the amount of coolant that goes through the engine. The engine will overheat if it remains in the “open” position due to excessive coolant flow. If it’s stuck in the “closed” position, not enough coolant will flow, causing the engine to overheat again.

How to Check the Radiator Daily

Don’t let a radiator leak go unchecked. Check your radiator regularly to prevent it from leaking. 

  1. First, turn off the heater. Then, take a bucket and place it underneath the radiator. 
  2. Once the water has stopped dripping, replace the bucket with a radiator pressure tester. 
  3. This will tell you what the pressure is of your radiator’s pressure. If it is below 50psi, you have a leak.
  4. Continue to add the required pressure until you find the leak. If the radiator is still under warranty, contact the supplier and they will send a technician to fix the leak free of charge!

Five Tips to Avoid Vehicle Overheating

As the temperature rises, it is essential to be mindful of the possibility that your vehicle can overheat. Here are some suggestions for preventing your vehicle from overheating:

Verify Coolant Level

If your vehicle is overheating, you should first check the coolant level. If it’s too low, keep adding until the entire line is achieved. If there are bubbles in the coolant or if it has been a while since the system was flushed, you may also need to purge the air from the cooling system.

Check for Leaks in the Radiator Hose

If your vehicle is overheating, one of the first things you should inspect for is a leaking radiator hose. If the hose has fractures or holes, overheating may be the source. To check for leaks, inspect the hose for indications of wear and tear.

If the hose has any fractures or holes, it must be replaced. If the hose is in excellent shape, check for soft places by pressing on it. These spongy areas may be an indicator of a leak. If you discover a leak, you must immediately replace the radiator hose.

Investigate the Radiator Cap and Thermostat

Checking the radiator cap and thermostat as The radiator cap is responsible for maintaining the right amount of pressure in the cooling system. In contrast, the thermostat helps control the engine’s operating temperature. If one of these components is malfunctioning, your vehicle might overheat. 

  1. To examine the radiator cap, remove it from the radiator and inspect it for cracks or other damage. 
  2. If the cap becomes damaged, it must be replaced. To inspect the thermostat, take it out of the engine and set it in a kettle of boiling water. 
  3. The thermostat should be set to around 195 degrees Fahrenheit to open. Replacing is the only option if it does not need to be repaired again or damaged severely.

Verify that Your Fan is Working Correctly

If your vehicle is overheating, you should ensure that the fan is functioning correctly. If not, your vehicle will have to work more to cool down, which might result in overheating. There are several methods to determine whether your fan is functioning correctly.

If the air flowing out of the vents is not as forceful as it should be, the fan must be fixed.

The fan may not work properly if the engine sounds louder than usual. If you suspect a problem with your fan, you should have a mechanic examine it. 

Do Not Drive Your Car Without Having It Inspected by a Professional

If your vehicle is overheating, you should have a professional mechanic examine it immediately. They’ll diagnose and provide a solution.

Several factors can cause a vehicle to overheat, including a coolant leak, a malfunctioning radiator, or a clogged cooling system. 

  1. A skilled mechanic can determine the source of the issue and correct it. 
  2. In certain instances, engine overheating may be brought on by something as simple as low oil levels. 
  3. In this scenario, the technician will add oil and send you your way. 
  4. The mechanic will likely recommend replacing the component if the overheating is caused by a more serious issue, such as a blown head gasket. 
  5. This is a costly repair, but keeping your vehicle operating smoothly is necessary. 
  6. Regardless of the source of your car’s overheating, get it inspected as soon as possible by an expert.


Never take automobile overheating lightly since it may be very severe and hazardous. We hope this article has provided insight into why your vehicle is overheating, as well as advice on how to stop it before it becomes a significant issue.
