What to do when your car is overheating

Car Overheating
  • Don’t ignore signs of overheating – it could cause serious engine damage

  • Stop somewhere safe as soon as you can

  • Don’t open the bonnet – wait for the NRMA while the engine cools

The first sign your car’s engine is overheating is usually the needle on the temperature gauge rising towards the red zone, or the ‘check engine’ or ‘temperature’ warning light on your dashboard illuminating. 

Keep in mind that even if you don't suspect your vehicle has overheated or the needle on your gauge has not risen, it's never a good idea to open the bonnet or remove the radiator cap after driving as it can cause serious injury.

Coolant in the radiator is extremely hot and will eventually boil and steam will rise from under the bonnet if the car has overheated. 

If this happens to you, stay safe by following these three simple steps from the NRMA:

Three steps to safely deal with a car overheating

  1. As soon as you’re aware that the car may be overheating, stop somewhere safe, if possible away from traffic and other road hazards. Continuing to drive can quickly cause major damage.

  2. Call 13 11 11 for NRMA roadside assistance or book online via the my nrma app and we will quickly dispatch a road service patrol to assist you.

  3. Don’t open the bonnet or remove the radiator cap while you’re waiting for a patrol. Allow the engine to cool, which can take more than an hour.

In some cases, the problem will be repaired and you will be able to continue on your way. 

If it’s suspected that your car’s engine has been damaged, or the overheating problem cannot be fixed at the roadside, your car will need to be towed to a service centre.

Regular checks of your car’s cooling system and proper servicing will significantly reduce the risk of overheating.

During days of extremely hot weather, NRMA roadside assistance usually receives a high volume of calls.

You can save time by making a quick request for help via the my nrma app.
