A puff of white smoke, a [temperature needle](<https://www.thedrive.com/maintenance-repair/33406/how-to-fix-a-temperature-gauge>) beginning to make its way toward the red, and there, a distinctive acrid smell of what can only be boiling coolant. And then, the needle races toward the red and that small puff of smoke becomes an impenetrable cloud. Yep, your car is overheating.

Don’t worry and don’t panic, you’re not the first person who’s had to deal with an overheating car and you won’t be the last, as even our electrified truck future requires complicated thermal management systems. Most of the issues that might occur are relatively inexpensive, but there are some outliers.

To better understand your automobile and prepare for the event of your car overheating, *The Drive’s* info team is here to answer all of your burning questions and guide you through the causes of heat build-up and what you need to do to stop it. Now, let’s cool down and learn!

## Why Is My Car Overheating?

Given the myriad of issues that cause a car to overheat, *The Drive’s* crack informational team put together a short list of the most common reasons as to why your temperature gauge now reads “Hell.” Let’s get into it.

### Bad Radiator

A coolant leak can occur when a foreign object is kicked up by the truck in front of you and penetrates the [radiator](<https://www.amazon.com/s?tag=drive09e6-20&k=radiators&ref=nb_sb_noss>). The resulting cascade of fluid will see your engine overheat, warp your heads, contaminate your oil, and leave you stranded on some lonesome highway. None of those options are good for your or your cars health

### Bad Radiator Hose

As your car ages, the plastic and rubber hoses that feed the engine its vital fluids can snap and break. You may notice a few drops of coolant on the ground that turns into a flood. Likewise, a car’s hoses are clamped down by hose clamps, little metal circles that feature some type of device to sinch them tight. They too are subject to the inevitable maw of death.

### Bad Thermostat

This little part manages the flow of coolant from the radiator to and from the engine and can become stuck open or closed. Neither is a good thing for your engine and will cause it to overheat.

### Head Gasket

In the automotive lexicon, “blown head gasket” is a phrase that is about as bad as it gets for the average consumer because it typically translates into many thousands of dollars in repairs, i.e. coolant gets into the combustion chambers, your engine and wallet explode.

### Bad Radiator Fan

All cars have radiator fans that assist in cooling the car’s coolant/antifreeze. If that goes out, it can’t cool the fluid and your car will overheat.

## What Do I Do When My Car Overheats?

As the brilliant Douglas Adams once wrote in *The Hitchhikers Guide to the Galaxy*, “Don’t Panic.”

Your car overheating shouldn’t propel you into a frenzied fluster, that will only make you nuts and won’t solve the underlying problem. Stay calm and pull over to the side of the road. If your A/C is on, turn it off. If you can’t pull over and stop the car, turn on the heater, as it will draw in the warm air from the engine and dispel it into the cabin. We suggest rolling down the windows at this point so you don’t overheat yourself.

Once you’re in a safe location, pop the car’s hood and allow it to cool for 5-10 minutes. You can then do a visual inspection of the engine bay to see if the overheating issue was caused by a bad hose, loss of coolant pressure, leaky radiator, or bad fan. If you can repair one of those issues with what you have in the car, do so and head to a mechanic’s to have it properly repaired. If you can’t, you’ll likely be calling a tow truck.

## What Shouldn’t I Do When My Car Overheats?

The worst thing you can do is panic or keep driving with a laissez-faire attitude hoping it will all go away. Likewise, don’t crank the A/C or put the pedal to the metal... Pull. Over.

## Dangers Of Driving With an Overheated Engine

As with any broken thing, the more you use that thing, the more it’s going to break. And at a certain point, there’s no fixing a pile of metallic shrapnel. Here’s what can happen if you keep driving while your engine is overheating.

### Damage Your Radiator

Your radiator is likely already damaged, but in the early stages of overheating, it can be repaired. The more you drive on it, the more you’re likely to see burst hoses burst, failed radiator stems, and exploding cooling systems.

### Damage Your Engine

Here’s where you can really be a blight on your engine, as its parts are rated to handle certain operating temperatures. If you go over those temperatures for a prolonged period of time, you’re going to find yourself with warped metal, from heads, pistons, cranks, cams, and everything in between. That leads us to the most damaged aspect of all: your wallet.

### Damage Your Wallet

Yeah, you heard us. The longer you drive your overheating car, the higher your repair bill is likely going to be. Every part that fails has a cost, both in the part itself, labor, and downtime as your car sits in the mechanic’s bay.
