What Causes a Car Engine to Overheat?
1 Answers
Introduction to the causes of car 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 lack of water in the radiator. If the owner fails to promptly inspect and replenish the coolant, it can easily result in engine overheating. 2. Radiator leakage: Broken or improperly connected radiator hoses can cause leaks, obstructing water circulation and severely leading to engine "boiling over". 3. Cooling fan malfunction: Damage to the cooling fan or short circuits in the wiring can cause the fan to operate improperly or at a slow speed, preventing the engine's heat from dissipating and naturally causing the engine temperature to rise. 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 inevitably be affected, preventing the engine's heat from being effectively dissipated. 5. Water pump failure: A malfunctioning water pump disrupts the timely circulation and renewal of the engine's heat-conducting water, causing the water temperature to rise rapidly after the engine starts. At this point, the water temperature warning light on the dashboard will also illuminate. 6. Exhaust issues: A blocked catalytic converter or a cracked pipe can obstruct engine exhaust, leading to engine overheating.
