What are the causes of engine temperature failure?

[StJulianna]

Here is an introduction to the causes of engine temperature failure: Insufficient coolant: Coolant is the medium for engine heat dissipation, and a lack of coolant will definitely cause engine overheating. Inspection method: Open the engine hood and locate the coolant reservoir. If the coolant level is below the standard line, it indicates insufficient coolant. Simply adding the same type of coolant can eliminate the engine overheating issue. Thermostat failure: The thermostat is the switch that controls the coolant circulation between the small and large loops in the engine. When the engine generates a large amount of heat, the thermostat must fully open to allow the engine cooling system to enter the large circulation loop. Otherwise, insufficient heat dissipation will occur, leading to engine overheating.
