How should a coolant recovery tank be mounted for effective operation?

The correct choice of mounting a coolant recovery tank as high as possible is essential for ensuring effective operation. This positioning takes advantage of gravity, helping to facilitate a better flow of coolant both during the cooling process and as it expands and contracts with temperature changes.

When the recovery tank is elevated, it allows for proper venting of air bubbles that may accumulate in the cooling system, enhancing the overall efficiency of coolant circulation. An elevated position helps maintain a consistent coolant level in the system by allowing gravity to assist in replenishing coolant back into the radiator as needed.

Positioning the tank properly can also prevent issues such as overflow or inadequate filling of the radiator, which can lead to overheating or engine damage.

Mounting the tank low or horizontally does not provide the same benefits, as these configurations could hinder proper coolant flow and air venting, which can create problems in the overall cooling system's efficiency.
