Turn On Your Hazard Lights

If your car has overheated and turned off, it’s important to turn on your hazard lights so that other drivers will be aware of the situation. Make sure that your turn signals are also on, as well as your emergency flashers.

Once you’ve turned on your hazard lights, put out a warning triangle so that other drivers will know to use caution when approaching.

Open Car Hood

After you’ve placed the warning triangle, open the car hood to allow the engine to cool down. Make sure to stay clear of the car if it starts up again.

Stand Clear To Rear Of Car

Once the engine has cooled down, stand clear to the car’s rear in case it starts up again. Again, this is for your safety and the safety of other drivers.

Allow Engine Cool

Leave the engine to cool down before doing anything else. This will help determine if the machine or the cooling system issue.

Top Up Coolant

If the engine appears to be OK, top up the coolant system. You can do this using either the official coolant or water. Ensure your car’s owner’s manual for the appropriate mixture.

Ok to Top up With Water?

You can top up your car’s coolant system with water, but make sure that the water you’re using is clean and not from a faucet. If there are any sediments or debris in the water, it can create a blockage inside your engine’s cooling system. So if you plan on using tap water, it should be filtered before you add it to your car.

Start & Move Car

Start the car and move it slowly to a safe place if everything looks OK. If the car overheats again, you should seek professional assistance as the issue is more than likely with your engine.

Check For Leaks

If there are any leaks while moving your car, shut off the engine immediately. If the car overheats again, it means that there is still an issue with either or both of the co

olant systems or oil.
