How to react if your car overheats?

It is more likely that your car overheats when the temperature is high, but if ever it happens in normal weather, there are 2 things you can check quickly to try and identify the cause of the overheating:

  • - The coolant level is low. Wait for the radiator to cool down and refill the coolant tank. Water can temporarily do the job if you have no coolant left, but make sure to complete with coolant as soon as you can.
  • - There is a leak in the cooling system. Unless the tank looks totally empty, top-up to be able to reach the nearest mechanic and ask them to pressure-test the cooling system. On the contrary, if the tank seems empty you should rather call for a tow truck.

However, if you’ve already excluded the first 2 hypothesis and you think that your car is overheating because of the hot weather, here below are a few tips to help you cooling it down:

  • - If you notice any sign of overheating, start by shutting off the air-conditioner and opening the windows. If this method isn’t efficient enough, keep your windows open, and switch on the heater. It won’t be the most pleasant experience for you and your passengers but it will allow vacuuming the heat away from beneath the hood.
  • - If you are stuck in traffic, you will prefer a smooth and slow driving rather than alternating between braking and accelerating. Braking generates a lot of friction, which will only contribute to increasing the heat.
  • - But as soon as you notice that the temperature gauge reaches the ‘hot’ level, slow down and grab the first opportunity to park your car. Note that temperature is generally cooler in storeys car park or if you don’t have much choice prefer grass, which will absorb the heat, to tarmac, which reverberates it. Then open the hood to speed up the cooling off.
