Coolant passes through the engine and removes the heat from it. It controls the engine’s temperature. When the coolant level becomes low due to leakage or neglect, then the engine cannot be cooled properly; this can cause car engine overheating.

2. Faulty thermostat

The thermostat regulates the flow of coolant between the radiator and engine. If it fails and stays in closed position then the coolant cannot flow through it and heat will quickly build up inside the engine resulting to car overheating.

3. Radiator Blocked or Damaged

The radiator dumps the heat from the coolant. Dirt, rust or internal blockage might diminish its performance, while broken radiator fins or leaks will prevent it from cooling correctly, and the engine temperature will rise, resulting in car engine overheating.

4. Defective Cooling Fan or Water Pump

The water pump distributes the coolant around the engine, and the cooling fan helps to cool the radiator, especially in slow-moving traffic. If one of them breaks, your cooling system won’t work properly, and your engine will overheat.
