What is the reason for the low idle water temperature of 09+000 Chevrolet Lefeng?

The reasons for high engine temperature are: water leakage in the cooling system or insufficient cooling water; Incorrect or invalid indication of water thermometer; There is too much scale in the cooling system, and the heat dissipation effect is poor; The radiator net or radiator core ventilation pipe is blocked by sundries, resulting in poor heat dissipation; The belt of water pump and fan is too loose or broken. The first thing to check is whether the radiator coolant is normal, and whether the radiator, radiator pipe and components are leaking.
