What Should You Do When You See That The Car Is Overheating?

Posted on April 2nd, 2025

 

Consider that you're cruising along, enjoying the open road, when something feels off.

Maybe there's a strange, sweet smell in the air, or your temperature gauge starts creeping into the red zone.

At first, you might brush it off, especially on a short trip around Oxfordshire.

But trust me, those small signs can be the difference between a minor issue and a major breakdown.

We all want a simple list to keep our car in check, right?

Knowing what to look out for can help you stay ahead of the game when the engine starts to overheat.

So, you’ve spotted the signs. Your heart skips a beat, worrying about the dreaded engine damage.

But here’s the thing: stay calm. Panicking won’t help.

The key is to assess the situation with a clear head, keeping safety top of mind. If you're on the move, find a safe spot to pull over.

Once stopped, turn off the engine. It may seem counterproductive, but it gives your car a chance to cool down.

The best move now? Wait. While the engine cools, take a moment to gather yourself.

Then, if you’ve got the confidence, you can check a few things yourself—coolant levels, belts, hoses—but knowing when to call in the pros is just as important.

Sometimes, a quick fix isn’t enough, and that’s when a recovery service is a lifesaver.

 

What To Do When You See Signs of Overheating

When you spot signs of overheating in your vehicle, it is important to understand these early indicators to prevent a potentially costly and inconvenient breakdown.

One of the most common signs is when you notice the temperature gauge on your dashboard edging towards the red zone. This gauge is your car's way of communicating that its engine temperatures are rising excessively, and it needs your immediate attention.

In case you see that steam or smoke begins to escape from underneath your car's bonnet, it's a clear signal that something is wrong in the engine compartment — usually because of coolant boiling over or a pressurised radiator cap failing to hold it all in.

Strange odours can also indicate trouble; if you detect a sweet, syrupy scent, that’s often coolant leaking, while a burning odour might hint at overheated oil or plastics. Therefore, knowing the early signs can save you a great deal of trouble and expense by allowing you to act promptly.

So, now that you know what to look for, let's talk about what to do when a car is overheating. The first and most important thing is to make sure of your safety.

If you’re in motion, calmly pull over to a secure spot, away from traffic. This step is detrimental not only for the safety of you and your passengers but also to help prevent engine damage that gets worse if ignored.

Selecting the safest spot might mean pulling off to a hard shoulder or stopping at the nearest lay-by, but wherever you choose, avoid sudden braking that might put you or others at risk.

Put your hazard lights on to signal to other drivers that you're stationary due to an emergency. If you can, open the vehicle's windows to release any excessive heat build-up inside the cabin.

Once you’re safely stopped, it's best to turn off the engine. This pause helps bring the engine's temperature down somewhat and minimizes further heat build-up.

After ensuring your vehicle is safely stopped and the engine is off, it’s time to play the waiting game. Attempting to pop the bonnet immediately is not advisable due to the risk of burns from escaping steam or hot components.

Instead, give it a good 20 to 30 minutes for the engine to cool sufficiently. In the meantime, stay clear of the bonnet's immediate vicinity, and provide any passengers with shade or a more comfortable waiting environment if conditions allow.

As the engine cools down, use this time to figure out your next steps. If you feel confident and have the right supplies, such as coolant or water on hand, check the coolant levels and top up if necessary. However, don't attempt to open the radiator cap while the engine is still hot.

After the cool-down period, you might try restarting the engine to assess whether the temperature gauge is back to its normal range. If it doesn’t show signs of stabilizing, it’s time to call in professional help to avert more serious damage.

For those residing in areas like Oxfordshire, considering a service like reliable vehicle recovery can save you from a potentially stressful situation. They offer trustworthy assistance to get you back on the road promptly and safely.

 

Diagnosing the Overheating Issue On Your Own

Once the initial heat has settled, you’re ready to inspect your vehicle and get to the bottom of the issue. Thankfully, diagnosing an overheating car isn't as complicated as it might first appear.

Start by carefully lifting the bonnet, but only after giving the engine enough time to cool down to avoid any burns.

The first thing to check is the coolant reservoir. The liquid should ideally sit between the ‘min’ and ‘max’ marks. If it’s below the recommended level, top it up—but first, figure out why the coolant level dropped.

Look for signs of contamination, such as oil droplets or discolouration, which could suggest a more serious problem, like a blown head gasket.

Also, check under the vehicle for any signs of leaks—a puddle of coolant can often indicate a loose hose or, in more severe cases, a cracked radiator.

Next, take a look at your vehicle’s belts and hoses, as they’re there for keeping the engine cool. Check the belts for signs of wear, such as cracking or fraying.

A snapped belt will stop the water pump from circulating coolant, causing overheating. Similarly, hoses should feel firm but flexible when cool, with no signs of bulging or leaks.

While you’re at it, inspect the radiator fins for blockages such as dirt or leaves—gently clearing these with a soft brush can help with airflow. However, if the blockages are significant, it’s best to leave this to the pros.

Deciding whether to call in the professionals is key. Even experienced drivers often turn to a mechanic to make sure everything’s running properly.

A mechanic will check the cooling system with pressure tests, verify the thermostat’s function, and make sure that the water pump is circulating coolant effectively.

If you find yourself in need of help, don’t hesitate to call a recovery service.

We'll tow your vehicle to a nearby garage where a more thorough diagnosis can be made, saving you from future headaches.

 

When to Call for Professional Help

If you’ve done your initial checks and things still aren’t adding up, it might be time to call in a recovery service for some expert help.

While you’ve managed the situation so far, some problems run deeper than they first appear. Issues like persistent leaks, an ongoing low coolant level despite topping up, or unusual sounds from the engine shouldn’t be ignored.

These are signs that professional intervention could save both your car and your wallet from further damage. Vehicle systems are complicated, and when your troubleshooting reaches its limit, it’s time to bring in the experts. 

If you’re unsure, towing your car to a professional for further inspection is a safe way to avoid further damage.

Although it might be tempting to keep driving short distances, ignoring an overheating issue can lead to more serious breakdowns, potentially requiring costly repairs. If the problem persists or worsens, don’t wait—let the professionals handle it.

When entrusting your car to a recovery expert, it’s important to consider how they approach repairs and customer care. A good service will treat your car with the care it deserves, keeping you informed throughout the process and offering advice to prevent future issues.
