What Is A Breather Catch Tank?
Breather Catch Tanks can be used to vent an engine, a dry sump tank, a rear end, or in any other application that requires controlled venting. The side port is connected to the vent line and the bottom port is used as a drain, any vapor that condenses is caught in the bottom of the tank. The pleated breather keeps any contaminates from entering the system.
What Is An Overflow Catch Tank & Air/Oil Separator Tank?
Overflow catch tanks keep oil and coolant from discharging onto the ground. Overflow catch tanks capture the overflow of fluid, while oil separator tanks capture any oil that is pulled into your vacuum lines. When using our catch tanks, the side port is used as the input, the bottom port is used as a drain, and the top port as a vent. When using our oil separator tank plumb between the valve cover and the "IN" side of the vacuum pump.
What Is A Coolant Expansion Tank?
Expansion tanks provide a high point in the coolant system where a cushion of air can be present. When the coolant in the system builds up in temperature the fluid expands and creates pressure. When under pressure the cushion of air compresses and provides room for the expanding coolant. Expansion tanks generally should be mounted higher than the engine and radiator to ensure that the engine and radiator are completely filled and the tank itself should only be partially filled to allow for expansion.
Why is There a Vent Fitting On Our Tanks With A Radiator Style Neck?
Expansion tanks are designed to provide a point in the coolant system where a cushion of air can be present. When coolant rises in temperature and expands the tank provides a place for the expanding coolant. If the tank is filled too high and does not have a adequate room for expansion or if the coolant temperature rises above normal the pressure in the system may become to great and need to be relieved to prevent damage to the tank and other system components. The pressure rated cap and vent in the tank’s neck allow for this pressure release. If the vent is removed or plugged the radiator cap will not be able to release any excess pressure. The vent is built into the stock cap and removal will cause the tank to expand and fail.
