What Causes Engine Overheating?

[OCarter]

Reasons for engine overheating: 1. Insufficient coolant: Prolonged water circulation during engine operation can gradually deplete the coolant in the engine's cooling system, leading to a shortage of water in the radiator. If the owner fails to promptly inspect, detect, and replenish the coolant, this can easily cause engine overheating. 2. Radiator leakage: Broken or improperly connected radiator hoses can cause leaks, obstructing water circulation and, in severe cases, leading to engine "boiling." 3. Cooling fan malfunction: A damaged cooling fan or short-circuited wiring can cause the fan to stop working or operate at a slow speed, preventing the engine's heat from dissipating and naturally raising the engine temperature. 4. Thermostat failure: The thermostat controls the flow path of the coolant. If it becomes stuck or fails, the engine's large and small circulation cycles will be affected, and the engine's heat cannot be effectively dissipated. 5. Water pump failure: If the water pump malfunctions, the water that conducts heat in the engine cannot circulate and renew in time. After the engine starts, the water temperature will rise rapidly, and the water temperature warning light on the dashboard will also illuminate.
