Why does the thermostat of Geely Vision not open after replacing the coolant?
1 Answers
The reasons why the thermostat of Geely Vision does not open after replacing the coolant are as follows: Internal damage to the thermostat: The thermostat automatically adjusts the amount of water entering the radiator based on the temperature of the coolant, changing the circulation range of the water to regulate the cooling system's heat dissipation capacity, ensuring the engine operates within the appropriate temperature range. The thermostat must maintain good technical condition; otherwise, it will seriously affect the normal operation of the engine. Damage to the thermostat opening valve: If the main valve of the thermostat opens too late, it will cause the engine to overheat; if the main valve opens too early, it will prolong the engine warm-up time, resulting in the engine temperature being too low. Air not completely purged: If the air is not completely purged after replacing the coolant in the Geely Vision, it will cause the thermostat not to open.
