Swirl Pots

It is standard racecar practice to use a swirlpot to remove air pockets in the cooling system

If correctly designed and positioned, the swirl pot will "spin" the coolant around inside it

This will cause any air trapped in the coolant to seperate out

Percolation will cause this air to rise in the swirl pot where it it is able to escape through the small vent in the top back to the top of the header tank

Can also be used to put a useful change of direction into the cooling system plumbing
