[Healeys] Coolant recovery system

[Oudesluys]

Have a look at the overflow tank from an Audi or VW in a junk yard. They 
are a round plastic sphere with a pressure cap. The pressure for the 
valve in the filler cap to open is way to high for the cooling system of 
the Healey so you should modify it. I have used one in the past and just 
removed the sealing O-ring in the cap to make the overflow tank 
pressure-less.
