Identifying and Dealing with Cars Overheating


Whatever the make or model, there are a number of common issues that all cars will suffer from time to time. From flat batteries to flat tyres, these faults always crop up at the most inconvenient times.

Cars overheating is another problem that some vehicles are susceptible to, and occurs when the engine becomes too hot, increasing the risk of severe damage to many components. From cracked head gaskets to warped cylinders, this could prove costly.

Taking immediate action when you think your car may be overheating is the best way to limit any negative effects, and being able to identify when it is happening and knowing what to do is vital for this.

Identifying an Overheating Engine

Outside of steam rising from under the bonnet (probably a clear sign that your should have acted sooner), the biggest indicator of an overheating engine is staring you in the face – quite literally.

One of the most important dials on the dashboard in front of you displays the temperature of your engine. Should this begin to rise, or any other temperature-based warning lights activate, it could spell danger.

If you feel hot air coming out of your car’s air conditioning system, this could also indicate a heating fault – or at least warn of an imminent one.

Causes of Engine Overheating

Engine overheating could be as a result of a number of factors. One of the most common is a lack of a sufficient level of coolant (sometimes known as ‘antifreeze’), the job of which is to keep the engine at a low enough temperature to operate correctly. Keeping an eye on the amount of coolant during a routine under-the-bonnet check, and refilling as necessary, should be enough to prevent this from developing into an issue.

Similarly, a low oil level can present a problem. Oil is your engine’s lubricant, ensuring that parts do not suffer from wear and tear through friction. Friction is another major cause of heat – therefore less oil means greater temperatures.

A misfiring thermostat can convince an engine that there is no issue with the temperature, meaning that none of the contingency cooling methods need be employed. This is the likely issue if you see smoke coming out of your engine and there has been no indication of excessive temperatures from your dashboard dials.


The first thing to do when any signs of overheating materialise is to pull over and turn off the engine. If possible, raise the bonnet and allow the engine to cool (this is easier during the colder months).

Turn off any air conditioning – while it may cool down the interior of your car, A/C systems increase heat elsewhere, including the engine and surrounding components.

If the cause of the overheating is not immediately obvious (coolant levels seem fine, engine oil is topped up), take your car to professional mechanics to cast their eye over.
