What causes the Teana engine to overheat?

[DeHope]

If the engine overheats, it may be due to clogged pipes in the cooling system, prolonged use of old coolant, or a damaged thermostat. Clogged pipes: If the air pump's outlet pipe is clogged, it will cause the air pump to operate under high internal pressure and fail to inflate. The solution is to remove and replace the clogged pipe with a new one. Insufficient or improper coolant: Insufficient or improper coolant cannot effectively dissipate the heat generated by engine components, leading to excessively high water temperature. Damaged thermostat: If you plan to remove the thermostat, you should block the small circulation loop to ensure that all coolant is cooled by the radiator.
