Header Tanks, Swirl Pots & Spares
Swirl Pots: MFRAD22
It is Standard Race Car 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 separate 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.
