How to Solve Low Engine Coolant Temperature?

[DiZoe]

Solutions for low engine coolant temperature: 1. Drive for a while to allow the temperature to rise, and try to avoid running the engine in high RPM zones; 2. Replace the thermostat. When the thermostat fails to close due to damage, it causes the engine cooling system to remain in a large circulation state at all times, ultimately leading to the engine temperature being too low and difficult to rise. When the engine starts cold, the coolant inside the engine is restricted to circulate within the engine water passages, which helps to quickly increase the engine temperature. When the engine reaches normal operating temperature, the thermostat opens (the thermostat acts as a valve for the engine's large and small circulation loops), allowing the coolant to flow from the engine water passages into the radiator. After being cooled by the radiator, it flows back to the engine to maintain the normal operating temperature of the engine.
