Engine overheating occurs when one of its systems fails. Let us have a closer look at some of the main causes of engine overheating and how to eliminate them.


  • Faulty thermostat
  • Coolant leakage
  • Loose or torn water pump
  • Clogged or blocked radiator hoses
  • Defective radiator cap valve
  • The air filter is clogged
  • Defective electronic control system

I think every car owner knows how important it is to maintain the thermal regime of the engine, especially in the summer. First of all, normal cooling is prevented by radiator clogs – its inability to pass air. Radiators clog-up quickly because of dirt, dust, fluff.

The engine starts to overheat, especially in traffic jams, when the clogged radiator is not able to cool the engine. If this happens you need to examine the radiator and if necessary wash it.

Another of the main causes of engine overheating is the thermostat. Initially, the cooling liquid – antifreeze – passes through a small circle: from the engine to the pump and back. At a certain temperature of heating of the coolant, the thermostat valve opens, and then the antifreeze opens a large circle of motion: to the radiator of the car. The only way to fix issues with thermostat is to change it.

Another most common reason for engine overheating are the hoses in the cooling system. It’s possible for dirt to get into your coolant department. If this happens, the flow of fluid through your hoses can be blocked, causing engine to overheat.

In some cases, it’s difficult to find the exact cause of the engine overheating. The best and the most effective solution for the car owners in this situation is to turn to the nearest auto repair shop. Experienced mechanics will be able to diagnose the problem and eliminate it.
