Most drivers have seen it before – a car pulled over on the side of the road with steam or smoke pouring from beneath the hood, the owner looking on nervously. An overheating car isn’t a pretty sight, but what should you do if it happens to you? And what can you do to ensure it doesn’t happen in the first place? We’ll answer both questions and more in this article.

Before we get into how overheating can be responded to and prevented, let’s talk about how it actually happens. Your car is designed to resist overheating, so if it has begun to get too hot, that’s often an indication that something is amiss. Here are a few common causes as to why your car may be running hot:

Every modern car is made with a coolant system that helps keep internal temperatures from climbing too high. Leaks, blockages or pump malfunctions in this system can all result in your engine overheating.

The coolant in your engine is regulated by your car’s temperature gauge, which determines how much is necessary to maintain an appropriate temperature. If anything is wrong with this system, it could be misreading the proper amount of coolant to provide.

Most drivers know oil plays a crucial role in lubricating a car’s moving parts, but it also removes excess heat from the engine. Accordingly, low oil levels can correspond with high engine temperatures.

As the name suggests, your radiator fan works to cool your car’s internal temperatures. If it stops running, or even runs at improper levels, that can be enough to cause your car to overheat.

If you’re unsure what’s causing your car to overheat, it’s always a good idea to find a reliable mechanic who can diagnose and service your car, and get protection in case your car overheats while you’re on the road.

Fortunately, most cars will not overheat without letting you know. There are several noticeable signs:

If you notice any of these signs, don’t wait to see if they get worse! Pull over right away and turn your car off to give it a chance to cool down.

If your car begins to overheat, it’s important to act fast. Running on high heat for too long can cause serious damage and potentially put you and your passengers at risk. Follow these steps at the first sign of overheating:

At first sign of anything unusual like strange sounds, or a failure to start at all, stay put, leave your engine off, and call roadside assistance.

Overheating poses a risk to both you and your car, so it’s best to avoid that situation in the first place. From preventative maintenance to tricks you can use in a pinch, there are many ways to help your car stay cool. Here are some of the easiest ways to do it:
