Today I Got The Breather Catch Tank For Radiator
Aluminum Made
What Does It Do ?
Short Answer : Eliminate the air bubble from over heating
Briefly :
By mounting the tank high up in the engine compartment, Oe can be assured that of a fully filled system with room for air expansion, thus reducing chances of overheating due to air-lock.
Once the thermostat opens, the hot coolant bypasses the radiator to pass through the tank, and is returned, hot, to the water pump inlet to re-enter the engine housing ports.
Its purpose is first to collect air/vapor in an upper, stagnant chamber.
Then by thermal expansion of the fluid and gas, it purges the collected air into the vented overflow bottle by way of a 3rd hose that ends in the bottle below the coolant level.
Air bubbles rise to the top and vent to the atmosphere. Upon cooling-contraction, coolant from the bottle is pulled back into the system.
The coolant that flows to the separation tank comes from the top of the thermostat housing, where a mini chamber is cast into the housing.
The entry into this chamber can be seen after removing the fill cap as a 10mm hole. The only chamber exit is the hose to the separation tank.
[I]The purpose of the mini-chamber is to encourage any air that is passing below, from the open thermostat to the radiator, to rise up and be sent ( with coolant ) through the small bypass line to the separation tank
