  • Problem with the radiator. 
  • Leaking coolant in the cooling system. 
  • Stuck thermostat. 
  • Blown head gaskets. 
  • Broken fan/s. 
  • Low oil levels. 
  • Broken water pump.

Temperature gauge displays a temperature over 200F

The ideal operational temperature for a car engine is between 195 and 200F. If your temperature gauge reads over 210F your engine is overheating. 

The hood feels hot

If your engine is overheating the hood of your car will feel hot to the touch. It is normal for your car hood to become hot when you are driving but if you are unable to place your hand on the hood of your car for 10 seconds without burning it, this is a warning sign that the engine could be overheating. 

Warning light on the dash

An overheating engine will often follow the display of a warning light on the car dashboard. Some models will have a warning light that flashes when the engine is close to overheating, others will indicate when there is an issue that can lead to an overheated engine.

The check engine light should never be ignored and the same goes for any of the warning lights that appear on the dash. 

Ticking sound coming from the engine

When there is not enough engine oil lubricating the moving parts inside your car engine, it can cause an audible ticking sound. When engine parts are not moving smoothly due to a lack of lubrication, this can cause the engine to overheat. 

Leaking coolant

When an engine doesn’t have enough coolant inside the cooling system it can quickly overheat. If you notice coolant leaking from below your car, you will need to rectify this issue as soon as possible. 

Reduced acceleration

If you notice your car is taking longer to accelerate or you are struggling to speed up at all, the car engine may be overheating.

Driving an overheating car too far and for a long period of time can cause the engine to completely meltdown and there will be no chance of repairing it if this happens.

If the car overheats to 80F (or more) over its regular functioning temperature, the engine will be ruined. However, damage can begin from the moment your car begins to overheat. 

There are too many variables that can influence how long you can drive an overheating car to be able to give a one set amount of time or miles.
