An overheating engine is a serious issue that can be caused by various issues, such as a coolant leak, a faulty thermostat, or a broken radiator fan. If ignored, it can lead to major engine damage and costly repairs. However, acting quickly and correctly when your engine begins to overheat can help prevent long-term harm. Signs of overheating include a rising temperature gauge, steam coming from the hood, or strange smells from the engine bay. What are the essential steps to take when your car’s engine overheats?
DURING DRIVING TURN ON THE HEATER
Turning on your heater helps draw excess heat away from the engine, allowing it to release into the air more effectively instead of building up inside the vehicle. If using the heater isn’t an option, roll down the windows to improve airflow. If your car has air conditioning, switch it on as well. This can temporarily reduce engine temperature until you can stop.
STOP DRIVING IMMEDIATLY BEFORE FURTHER DAMAGE
If your vehicle begins to overheat while you’re driving, the first priority is to ensure your safety and prevent further damage to the engine. As soon as it is safe to do so, carefully pull over to the side of the road—preferably on level ground, but if you’re on an incline, choose a secure location where your vehicle will remain stable. Once stopped, turn off the engine completely. It is critical that the engine is no longer running and has time to cool before you attempt to inspect the vehicle or exit.
Allow the engine to sit and cool for at least 15 to 30 minutes. Avoid turning off the ignition without properly shutting down the engine, as this could cause additional stress on the cooling system. While waiting, you can open all windows, vents, and even the sunroof (if applicable) to promote airflow and reduce heat inside the cabin.
Once the vehicle has cooled down, contact a certified mechanic or local auto repair service for assistance. Continuing to drive an overheating vehicle can lead to severe engine damage, so professional evaluation is strongly recommended before operating the car again.
CHECK THE COOLANT LEVEL
Begin by inspecting the coolant level only after the engine has completely cooled down, as opening the system while it’s hot can be dangerous. Start by examining the radiator, the coolant reservoir, and, if your vehicle has one, the overflow tank. These areas will help you determine whether the cooling system is low on coolant or in need of antifreeze.
If the coolant levels appear adequate and there are no visible signs of a leak, yet the engine continues to overheat, the issue may lie elsewhere—such as a faulty thermostat or a malfunctioning temperature sensor. In such cases, further diagnostic testing by a qualified technician is recommended.
