To deal with an overheating engine yourself:

  • Make sure the AC is turned off.
  • Turn the heater on as it will blow excess heat from the engine into the car.
  • Put car in neutral or park and then rev the engine.
  • Finally, make sure to pull over, wait 15 minutes or so (to cool) and then open the car’s bonnet. Be very careful when doing this as hot steam may come blasting out.

 

NEVER remove the radiator cap while the engine is hot. This can cause serious burns on your body.
