What Causes Coolant Overflow Without Overheating?

[DeOscar]

Coolant overflow without overheating indicates a malfunction in the vehicle's engine circulation system, which prevents the effective circulation of coolant within the engine, leading to the overflow issue. To effectively resolve this problem, the vehicle's circulation system needs to be cleaned. Additionally, it is necessary to check whether the engine thermostat is functioning properly. More relevant information is as follows: Vehicle Cooling System: The vehicle's radiator is part of the cooling system, which includes components such as the radiator, inlet and outlet hoses, etc. Radiator Core: The coolant flows inside the radiator core, while air passes outside the core. The hot coolant dissipates heat to the air and cools down, while the cold air absorbs the heat released by the coolant and warms up. Therefore, the radiator can also be referred to as a heat exchanger.
