What Causes the Engine Temperature to Rise?

[DiStella]

The reasons for engine temperature rise include: 1. Insufficient coolant: Prolonged water circulation during engine operation can lead to coolant loss in the engine cooling system, resulting in a shortage of water in the radiator. If not detected and replenished in time, this can easily cause the engine temperature to become excessively high; 2. Radiator leakage: Broken or improperly connected radiator hoses can cause leaks; 3. Cooling fan malfunction: Damage to the cooling fan or short circuits in the wiring can prevent the fan from operating or cause it to rotate slowly, which hinders the dissipation of engine heat and naturally leads to a rise in engine temperature; 4. Water pump failure: If the water pump fails, the water that conducts heat in the engine cannot circulate and renew in time, causing the engine temperature to rise rapidly after starting.
