Although newer vehicles are much less likely to overheat, given the wrong set of circumstances, they still could. A lack of coolant, broken cooling fan, fan belt or even a split radiator hose can all cause your temperature gauge to skyrocket.
If your interior heater starts to blow out cool air, you see your temperature gauge rising, your warning light comes on, or you see steam rising from underneath your bonnet the chances are that your engine is getting very, very warm and you need to act quickly to minimise any lasting damage.
In this situation we would always recommend calling your breakdown service to have your car recovered.
While you wait for your breakdown service to arrive, there are a few things you can do to help your engine cool down.
