Coolant Expansion Tank Function:

The breather tank serves as a coolant expansion tank (also called overflow tank or reservoir) for your cooling system. As coolant heats up during engine operation, it expands and needs somewhere to go. The expansion tank provides this overflow capacity, preventing coolant from being expelled through the radiator cap. When the engine cools down, the coolant is drawn back into the radiator, maintaining proper coolant levels in the system.

Aluminum Construction:

The tank is constructed from quality aluminum, providing excellent durability and heat resistance. Aluminum resists corrosion from coolant and withstands the heat of the engine bay. The construction is robust enough to handle the pressure and temperature cycling of the cooling system. The aluminum body also dissipates heat effectively, helping to cool the overflow coolant before it returns to the radiator.

Transparent Sight Window:

The sight window allows you to monitor the coolant level in the tank without removing the cap. This makes it easy to check coolant levels during routine maintenance or before track sessions. The transparent window also allows you to see the coolant condition and color, which can provide insights into cooling system health. Regular monitoring ensures the system maintains proper coolant levels.

Multiple Inlet/Outlet Ports:

The tank features multiple ports that provide flexibility for different installation configurations. You can connect to the radiator overflow, coolant system pressure relief, or other cooling system components as needed. The multiple ports also allow for expansion if you want to add additional cooling system connections. The ports typically accept common AN fittings or barbed fittings.

Bottom Drain Valve:

The drain valve at the bottom of the tank makes maintenance and coolant changes simple. Simply open the valve to drain the tank when performing cooling system service. The bottom location ensures complete drainage. The drain valve is especially useful when flushing the cooling system or changing coolant.

Universal Application:

The universal design works with most vehicles regardless of make or model. The compact size fits in tight engine bays, and the included mounting bracket provides secure installation. The universal nature means you can use the same tank across multiple builds or transfer it between vehicles. The tank is popular in both street and race applications where a clean, functional expansion tank is needed.
