The Radiator: The Heat Exchanger
The radiator is a critical component of the cooling system, responsible for dissipating heat from the coolant to the air. It is essentially a heat exchanger that allows the coolant to lose its heat to the surrounding air. The radiator consists of a network of tubes and fins that increase its surface area, facilitating efficient heat transfer.
The radiator is usually filled with a mixture of coolant and water, which circulates through the engine block and cylinder head, absorbing heat. As the coolant flows through the radiator, it transfers its heat to the air, which is then dissipated through the radiator’s fins.
The Coolant Reservoir: The Expansion Tank
The coolant reservoir, also known as the expansion tank, is a separate container that holds excess coolant. Its primary function is to provide a buffer for the coolant system, allowing it to expand and contract as the engine temperature changes.
The reservoir is typically located on the driver’s side of the engine compartment and is connected to the radiator and engine block. It contains a mixture of coolant and water, which expands and contracts as the engine temperature increases or decreases. The reservoir helps to maintain a consistent level of coolant in the system, ensuring that the engine does not overheat or undercool.
Where to Add Coolant: Radiator or Reservoir?
Now that we have a basic understanding of the radiator and reservoir, let’s address the question of where to add coolant. The short answer is that you should add coolant to the reservoir, not the radiator. Here’s why:
