What Causes High Water Temperature in Small Cars?

[JuniperAnn]

Coolant leakage or insufficient coolant can cause the engine water temperature to rise. When the vehicle runs at high speeds, the generated heat cannot be transferred to the antifreeze in time, affecting heat dissipation. A cracked impeller or an impeller loosening from the pump shaft can slow down the coolant circulation speed. Thermostat failure, prolonged use of water as a medium leading to rust formation in the engine and radiator, and poor radiator heat dissipation are also contributing factors. Methods to prevent engine overheating: 1. Regularly clean the radiator to avoid severe blockage by fluff and insects. 2. Regularly check the antifreeze level and replenish it promptly to prevent shortage. 3. Periodically inspect the vehicle to ensure the radiator fan operates normally after the engine reaches normal temperature.
