Getting stuck in traffic is frustrating enough, but the situation becomes even more stressful if your car starts overheating. An overheating engine is a serious problem that can lead to costly repairs if not handled properly. If you notice your temperature gauge creeping up or steam coming from under the hood, taking immediate action can prevent permanent damage. Here’s what you should do if your car overheats while you're in traffic.
Recognizing the Warning Signs
Your car rarely overheats without warning. There are a few telltale signs that your engine is getting too hot, including a rising temperature gauge, warning lights on the dashboard, steam coming from the hood, or an unusual burning smell. If you experience any of these symptoms, your car is likely overheating, and you need to act fast.
Turn Off the Air Conditioning and Turn On the Heater
While it might seem counterintuitive, turning on your heater can help draw heat away from the engine. This can provide temporary relief while you figure out your next move. At the same time, turn off your air conditioning to reduce strain on the engine.
Shift Into Neutral or Park and Rev the Engine
If you’re stopped in traffic, shifting into neutral or park and gently revving the engine can help circulate coolant and push more air through the radiator. This small action may help prevent the temperature from rising further.
Pull Over and Turn Off the Engine
If you can safely move your vehicle to the side of the road, do so immediately. Shutting off the engine is the best way to prevent further damage. Open the hood carefully to let excess heat escape, but don’t touch anything under the hood just yet—hot coolant and steam can cause serious burns.
Check the Coolant Level
Once the engine has cooled down completely, check the coolant reservoir. If the coolant level is low, adding more can help cool down the engine. However, if the radiator is empty, do not add coolant immediately while the engine is still hot. Doing so can cause a sudden temperature change that may crack the radiator or other components.
Don’t Remove the Radiator Cap While the Engine Is Hot
Opening the radiator cap while the engine is hot can cause scalding steam and coolant to spray out, leading to serious burns. Always wait for the engine to cool before checking or adding coolant.
What Causes a Car to Overheat in Traffic
Overheating isn’t just caused by hot weather—there are several underlying issues that can lead to high engine temperatures. Some of the most common causes include:
- Low coolant levels – Without enough coolant, your engine can’t maintain a safe temperature.
- Leaking coolant system – A leak in the radiator, hoses, or water pump can cause a gradual coolant loss.
- Faulty thermostat – A broken thermostat can prevent coolant from circulating properly.
- Bad radiator fan – If your radiator fan isn’t working, heat won’t dissipate efficiently, especially when idling.
- Clogged radiator – Dirt, debris, and corrosion can block airflow and reduce cooling efficiency.
When to Call for Professional Help
If your car consistently overheats despite adding coolant, or if you notice coolant leaks, steam, or a strong burning smell, it’s time to get your vehicle checked by a professional. Driving with an overheating engine can lead to warped cylinder heads, blown head gaskets, or even complete engine failure.
