The twin swirl pot - header finally fitted

I have just discovered a new way to get to my oil filter, yippee.

Road test for hot to cold water tightness has to wait until wednesday :-(

and i might just have got a new servo and header tank.....to do just that :-)

We need a place to put the 'other' cap, of course!

Swirl pot encourages coolant to spin around as it flows through causing any air trapped in the coolant to separate out to the top.

The header or expansion is for holding expansion water which is 'sucked in' and 'pushed out' as the temperature falls / rises and contains 'air' in the space to be expanded into such that the system doesn't lose coolant when fully expanded at high temps, or starve of coolant when very cool.

Two separate tanks are really to do with size and space available. one 'biggun' could do the job of both, if at the right height size location etc.

I went for two side by side as you can connect the top of the swirl pot to the bottom of a side by side header tank, which is like having a really tall tank :-)
