Is there coolant in radiator fins?

The fins on a car’s radiator only dissipate the heat; it is the tubes that hold the coolant. The coolant circulates through the engine and radiator, absorbing heat from the engine. The heat is transferred to the air passing through the radiator.

When cleaning your radiator, it is important to avoid using products that contain acetic acid or sodium hypochlorite, as these can damage the radiator and potentially the engine. Instead, choose a cleaner that is safe for use on metals.

Why is my car overheating but coolant is full?

If your coolant is overheating, there are a few potential causes. One is an airflow issue – not enough air is flowing over the radiator to cool the fluid. Another is that the coolant itself is old and needs replacing. Additionally, coolant can overheat if it is not being effectively pushed through the cooling system. If you’re not sure what the cause is, it’s best to take your car to a mechanic to have it diagnosed.
